Scientists found that Johnson & Johnson recipients who got a Moderna booster experienced a 76-fold boost in their antibody levels, compared with a fourfold boost after a 2nd Johnson & Johnson dosage. At Friday’s meeting, Dr. Ofer Levy, director of the Precision Vaccines Program at Boston Children’s Hospital and a member of the advisory committee, encouraged regulators to move quickly, noting that numerous Johnson & Johnson receivers had actually already sought out unauthorized mRNA boosters on their own. Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own suggestion on Johnson & Johnson boosters. It is possible
that regulators will authorize a second Johnson & Johnson shot before they authorize mRNA boosters for Prior to & License recipients. People ought to consult with their physicians about whether it makes sense to get a Johnson & Johnson booster as quickly as it is authorized or wait for a possible mRNA booster, Dr. Schaffner stated.
Updated Nov. 9, 2021, 12:05 p.m. ET”These vaccines are working,”stated John Moore, a virologist at Weill Cornell Medicine. What do we understand about the advantages of a second dosage? Just recently, Johnson & Johnson brought out research studies that
it declares program that a booster shot of its vaccine will assist secure people versus Covid-19. It will raise the effectiveness of the vaccine overall, the company argues, and be especially useful versus new variants. Regulators have actually been crucial of the company’s data. Last month, the company announced the results of a clinical trial that found that 2 doses of the vaccine, given 2 months apart, have 94 percent efficacy in the United States versus moderate to severe illness, compared to 74 percent efficacy
after a single shot. Globally, nevertheless, the outcomes were less convincing. Worldwide, the efficacy of a second dose of the vaccine was 74 percent, up from 66 percent after one shot. And the statistical unpredictabilities around those estimates make it difficult to identify just how much better 2 doses are than one. On the other hand, it appears that a 2nd dosage does enhance protection versus extreme illness, with an approximated efficacy of 100 percent. Regulators have actually criticized the study’s short follow-up duration. Why didn’t they suggest an mRNA booster rather of another Johnson & Johnson shot
? The F.D.A. panel voted only on whether to recommend a second Johnson & Johnson shot on Friday. But some researchers have suggested that blending and matching vaccines may
supply much better defense than getting 2 dosages of the exact same shot.

? The F.D.A. panel voted only on whether to recommend a second Johnson & Johnson shot on Friday. But some researchers have suggested that blending and matching vaccines may
supply much better defense than getting 2 dosages of the exact same shot.
And initial data from a study conducted by the National Institutes of Health suggests
that the approach has pledge. The research study, which has not yet been examined by specialists, included nine different groups
of participants, of roughly 50 individuals each. Each group got a different vaccine and booster mix; some people received a booster dosage of the same brand as the original vaccine, while others changed to a various brand name for their booster. Scientists found that Johnson & Johnson recipients who received a Moderna booster experienced a 76-fold boost in their antibody levels, compared with a fourfold boost after a 2nd Johnson & Johnson dosage. A Pfizer booster prompted a 35-fold increase in antibodies.” To me that information looked quite solid,”stated Dr. Moore, who was not associated with the research study. The F.D.A. has actually not yet scheduled a main vote on whether to recommend mRNA boosters for Johnson & Johnson receivers.
“We have actually not examined those data in detail,”Dr. Peter Marks, the F.D.A.’s leading vaccine regulator, said on Friday. The firm might authorize an mRNA booster for Johnson & Johnson receivers in the future, he stated, although he
did not supply anymore info & about the timing of such a decision. At Friday’s conference, Dr. Ofer Levy, director of the Precision Vaccines Program at Boston Children’s Hospital and a member of the advisory committee, encouraged regulators to move swiftly, keeping in mind that numerous Johnson & Johnson receivers had actually currently sought out unauthorized mRNA boosters by themselves.”In the real world, all these kinds of combinations or additional boosters are already taking place, so I believe it’s a matter of some seriousness for F.D.A. to help arrange out what is admittedly a difficult and complicated scenario,”he said. What happens & next? The F.D.A. will evaluate
the panel’s recommendation and provide a final decision, which might come within a couple of days.
Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own recommendation on Johnson & Johnson boosters. Its members will choose whether to recommend the chance ats all, in addition to who must be eligible. The C.D.C.’s director, Dr. Rochelle P. Walensky, will then issue the firm’s official standards on boosters. These standards are extremely prominent for physicians, drug stores and healthcare providers. What should I perform in the meantime? For now, sit tight. No booster has actually yet been authorized
for Johnson & Johnson receivers– the process is still underway.”I think of by this time next week, the federal government’s health experts will have made a recommendation to the American people about what they must do,”Dr. Moore stated. It is possible
that regulators will authorize a second Johnson & Johnson shot before 2nd authorize mRNA boosters for J. & J. recipients. If that happens, individuals who got the Johnson & Johnson shot
will be”on the horns of a problem,”stated Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine professional at Vanderbilt University. People should seek advice from with their physicians about whether it makes sense to get a Johnson & Johnson booster as quickly as it is licensed or wait for a possible mRNA booster, Dr. Schaffner said.”A lot depends upon where you are and who you are,”he stated. People who are at high danger for severe illness and reside in locations where the infection
is surging may not desire to wait, he said
.
The Food and Drug Administration’s vaccine advisory panel unanimously voted on Friday to advise a 2nd dose of the single-shot Johnson & & Johnson vaccine for adults who had gotten their very first chance at least 2 months prior.
If the F.D.A., which normally follows the panel’s recommendations, licenses a second shot, the 15 million Americans who received the Johnson & & Johnson vaccine could quickly start getting boosters.
On Thursday, the same F.D.A. committee voted to license boosters for Americans who received the Moderna vaccine. The extra shots have actually already been licensed for Pfizer-BioNTech receivers.
Johnson & & Johnson states that a 2nd dosage of its shot boosts the levels of antibodies versus the coronavirus and is more reliable at preventing Covid-19.
“We wish to supply optimal protection versus Covid,” Dr. Penny Heaton, worldwide healing area head for vaccines at Johnson & & Johnson, stated at Friday’s meeting.
But F.D.A. personnel have revealed doubts about the quality of the research study. And a booster dosage of among the mRNA vaccines, either the Pfizer or Moderna shot, might use even higher defense, initial data recommend.
Here are answers to some typical questions.
Why didn’t officials advise boosters for people who got the Johnson & & Johnson vaccine earlier?
All of the vaccines licensed in the United States provide strong protection versus serious illness and death from Covid-19.
Over the summer, experts grew worried that mRNA vaccines were losing some of their effectiveness against infection, although their efficiency versus hospitalization was largely the same. Last month, the F.D.A. licensed a booster of the Pfizer-BioNTech vaccine for particular populations at high threat from Covid-19; an advisory recommended a booster shot of Moderna’s vaccine on Thursday for the same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine utilizes a customized adenovirus to deliver its instructions to human cells, and that distinction is reflected in how the vaccines are now performing. The Johnson & & Johnson vaccine started with a lower effectiveness than the mRNA vaccines, but it has actually disappointed much modification in its efficiency with time. Research studies of antibody levels have discovered little change over 8 months.
Data on the Johnson & & Johnson vaccine has been slower in coming, in part due to the fact that vaccine was not licensed until completion of February, 2 months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were temporarily paused while health officials investigated reports that an extremely small number of people had actually developed an uncommon blood-clotting condition after getting the vaccine.
How effective is a single dose of the Johnson & & Johnson vaccine?
The company’s clinical trials, performed before the Delta version was widespread, discovered that the Johnson & & Johnson vaccine had 72 percent efficacy in general in the United States, lower than the approximately 95 percent efficacy of the Pfizer and Moderna vaccines. The vaccine’s defense versus important or serious illness was greater, at 85 percent worldwide.
It is tough to make direct contrasts between the vaccines, which were checked in various areas and at various times.
All of the readily available vaccines appear to lose some effectiveness versus Delta, which might have the ability to dodge a few of the body immune system’s antibodies. Information recommends that the Johnson & & Johnson vaccine holds up well versus the variant.
Preliminary arise from clinical trials of nearly 500,000 health care workers in South Africa recommended that a single dosage of the vaccine had efficacy of as much as 96 percent against death and 71 percent versus hospitalization from infections triggered by Delta.
It was “a really big analysis and extremely clear outcomes showing that the single-shot J.&& J. vaccine provided considerable protection versus the Delta variation,” Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in Boston, stated in August. Dr. Barouch has actually performed studies for Johnson & & Johnson however was not associated with the South Africa trial.
The business likewise announced outcomes from another real-world study, conducted in the United States, last month. The research study, which has actually not yet been reviewed by specialists, discovered that the vaccine’s efficiency stayed stable at 79 percent through July, suggesting that it continued to supply great protection against Delta. It was 81 percent effective at preventing hospitalizations.
Oct. 15: This post has actually been updated to show brand-new research about the Johnson & & Johnson vaccine and brand-new regulatory advancements.
Researchers found that Johnson & Johnson receivers who received a Moderna booster experienced a 76-fold boost in their antibody levels, compared with a fourfold boost after a 2nd Johnson & Johnson dose. Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own recommendation on Johnson & Johnson boosters.

“We have actually not evaluated those information in information,”Dr. Peter Marks, the F.D.A.’s leading vaccine regulator, stated on Friday. The firm may license an mRNA booster for Johnson & Johnson receivers in the future, he said, although he
did not supply any more info & about the timing of such a decision. At Friday’s meeting, Dr. Ofer Levy, director of the Precision Vaccines Program at Boston Children’s Hospital and a member of the advisory committee, motivated regulators to move quickly, keeping in mind that lots of Johnson & Johnson receivers had currently looked for out unapproved mRNA boosters by themselves.”In the real world, all these sort of combinations or extra boosters are currently occurring, so I believe it’s a matter of some seriousness for F.D.A. to help arrange out what is undoubtedly a difficult and complicated situation,”he said. What occurs & next? The F.D.A. will examine
the panel’s suggestion and issue a final decision, which might come within a few days.
Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own suggestion on Johnson & Johnson boosters. Its members will decide whether to advise the chance ats all, along with who must be eligible. The C.D.C.’s director, Dr. Rochelle P. Walensky, will then issue the firm’s official standards on boosters. These guidelines are extremely influential for physicians, drug stores and healthcare companies. What should I do in the meantime? For now, sit tight. No booster has yet been authorized
for Johnson & Johnson recipients– the process is still underway.”I think of by this time next week, the federal government’s health professionals will have made a recommendation to the American people about what they ought to do,”Dr. Moore said. But it is possible
that regulators will license a second Johnson & Johnson shot before they authorize mRNA boosters for J. & J. recipients. If that occurs, individuals who got the Johnson & Johnson shot
will be”on the horns of a predicament,”stated Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine expert at Vanderbilt University. Individuals should consult with their doctors about whether it makes sense to get a Johnson & Johnson booster as quickly as it is licensed or wait for a possible mRNA booster, Dr. Schaffner stated.”A lot depends upon where you are and who you are,”he stated. People who are at high danger for major disease and reside in locations where the virus
is surging may not want to wait, he stated

The Food and Drug Administration’s vaccine advisory panel all voted on Friday to advise a second dosage of the single-shot Johnson & & Johnson vaccine for adults who had gotten their very first shot at least two months prior.
If the F.D.A., which typically follows the panel’s recommendations, authorizes a 2nd shot, the 15 million Americans who got the Johnson & & Johnson vaccine might quickly begin getting boosters.
On Thursday, the exact same F.D.A. committee voted to license boosters for Americans who got the Moderna vaccine. The additional shots have currently been authorized for Pfizer-BioNTech recipients.
Johnson & & Johnson states that a second dosage of its shot improves the levels of antibodies against the coronavirus and is more effective at preventing Covid-19.
“We desire to offer optimal security against Covid,” Dr. Penny Heaton, worldwide therapeutic location head for vaccines at Johnson & & Johnson, stated at Friday’s conference.
F.D.A. staff have actually revealed doubts about the quality of the research. And a booster dose of one of the mRNA vaccines, either the Pfizer or Moderna shot, might provide even greater security, initial data suggest.
Here are responses to some typical questions.
Why didn’t authorities recommend boosters for people who got the Johnson & & Johnson vaccine quicker?
All of the vaccines authorized in the United States offer strong protection against extreme illness and death from Covid-19.
Over the summer, professionals grew worried that mRNA vaccines were losing some of their effectiveness versus infection, although their efficiency against hospitalization was mostly unchanged. Last month, the F.D.A. authorized a booster of the Pfizer-BioNTech vaccine for specific populations at high danger from Covid-19; an advisory recommended a booster shot of Moderna’s vaccine on Thursday for the exact same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine utilizes a customized adenovirus to provide its guidelines to human cells, and that distinction is shown in how the vaccines are now performing. The Johnson & & Johnson vaccine started out with a lower effectiveness than the mRNA vaccines, but it has disappointed much modification in its effectiveness gradually. Research studies of antibody levels have found little change over eight months.
Data on the Johnson & & Johnson vaccine has been slower in coming, in part since vaccine was not authorized up until completion of February, two months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were temporarily paused while health officials investigated reports that an extremely little number of individuals had developed an unusual blood-clotting condition after receiving the vaccine.
How effective is a single dose of the Johnson & & Johnson vaccine?
The company’s scientific trials, conducted before the Delta version was extensive, found that the Johnson & & Johnson vaccine had 72 percent effectiveness in general in the United States, lower than the roughly 95 percent efficacy of the Pfizer and Moderna vaccines. The vaccine’s defense versus critical or extreme illness was greater, at 85 percent worldwide.
However, it is difficult to make direct comparisons in between the vaccines, which were checked in various places and at different times.
All of the available vaccines appear to lose some effectiveness versus Delta, which might have the ability to evade some of the body immune system’s antibodies. Information suggests that the Johnson & & Johnson vaccine holds up well versus the version.
Initial arise from medical trials of almost 500,000 health care workers in South Africa recommended that a single dose of the vaccine had efficacy of as much as 96 percent against death and 71 percent versus hospitalization from infections brought on by Delta.
It was “a huge analysis and really clear outcomes showing that the single-shot J.&& J. vaccine supplied substantial defense versus the Delta variation,” Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in Boston, said in August. Dr. Barouch has carried out research studies for Johnson & & Johnson however was not involved in the South Africa trial.
The company likewise revealed results from another real-world study, carried out in the United States, last month. The study, which has not yet been examined by professionals, found that the vaccine’s effectiveness remained stable at 79 percent through July, suggesting that it continued to supply good protection against Delta. It was 81 percent reliable at avoiding hospitalizations.
Oct. 15: This short article has actually been updated to show new research about the Johnson & & Johnson vaccine and brand-new regulatory advancements.
Scientists discovered that Johnson & Johnson recipients who received a Moderna booster experienced a 76-fold increase in their antibody levels, compared with a fourfold increase after a second Johnson & Johnson dose. At Friday’s conference, Dr. Ofer Levy, director of the Precision Vaccines Program at Boston Children’s Hospital and a member of the advisory committee, encouraged regulators to move swiftly, noting that many Johnson & Johnson receivers had already sought out unapproved mRNA boosters on their own. Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own recommendation on Johnson & Johnson boosters. It is possible
that regulators will authorize a second Johnson & Johnson license before 2nd authorize mRNA boosters for J. & License recipients. Individuals need to seek advice from with their medical professionals about whether it makes sense to get a Johnson & Johnson booster as soon as it is licensed or wait for a possible mRNA booster, Dr. Schaffner stated.

Here are answers to some typical concerns.
Why didn’t officials suggest boosters for individuals who got the Johnson & & Johnson vaccine earlier?
All of the vaccines licensed in the United States offer strong defense versus severe disease and death from Covid-19.
Over the summer season, professionals grew concerned that mRNA vaccines were losing some of their effectiveness against infection, although their efficiency against hospitalization was mostly the same. Last month, the F.D.A. authorized a booster of the Pfizer-BioNTech vaccine for certain populations at high danger from Covid-19; an advisory suggested a booster shot of Moderna’s vaccine on Thursday for the same populations.

Information on the Johnson & & Johnson vaccine has actually been slower in coming, in part since vaccine was not authorized until completion of February, 2 months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were briefly stopped briefly while health officials examined reports that a very little number of people had actually established an uncommon blood-clotting condition after getting the vaccine.
How effective is a single dose of the Johnson & & Johnson vaccine?
The business’s scientific trials, carried out prior to the Delta variant was extensive, found that the Johnson & & Johnson vaccine had 72 percent effectiveness in general in the United States, lower than the approximately 95 percent effectiveness of the Pfizer and Moderna vaccines.

it claims show that a booster shot of its vaccine will assist protect people against Covid-19. It will raise the effectiveness of the vaccine overall, the company argues, and be specifically helpful versus brand-new variants. However regulators have been critical of the company’s information. Last month, the company announced the outcomes of a medical trial that discovered that two doses of the vaccine, given two months apart, have 94 percent efficacy in the United States against mild to serious illness, compared with 74 percent efficacy
after a single shot. Worldwide, however, the outcomes were less persuading. Worldwide, the efficacy of a second dose of the vaccine was 74 percent, up from 66 percent after one shot. And the statistical unpredictabilities around those price quotes make it hard to determine simply just how much better two dosages are than one. On the other hand, it appears that a second dose does improve security against serious disease, with an approximated effectiveness of 100 percent. Regulators have actually criticized the research study’s short follow-up duration. Why didn’t they advise an mRNA booster instead of another Johnson & Johnson shot
? The F.D.A. panel voted just on whether to recommend a second Johnson & Johnson shot on Friday. However some scientists have suggested that blending and matching vaccines might
provide much better defense than getting 2 dosages of the very same shot.
And preliminary data from a study carried out by the National Institutes of Health suggests
that the approach has promise. The study, which has actually not yet been examined by experts, involved 9 different groups
of individuals, of roughly 50 people each. Each group got a various vaccine and booster combination; some individuals got a booster dose of the very same brand as the initial vaccine, while others switched to a different brand name for their booster. Researchers found that Johnson & Johnson recipients who received a Moderna booster experienced a 76-fold increase in their antibody levels, compared to a fourfold boost after a 2nd Johnson & Johnson dose. A Pfizer booster triggered a 35-fold boost in antibodies.” To me that data looked pretty solid,”stated Dr. Moore, who was not associated with the research study.

Why didn’t officials advise boosters for people who got the Johnson & & Johnson vaccine faster?
All of the vaccines authorized in the United States supply strong security versus severe illness and death from Covid-19.
Over the summertime, professionals grew concerned that mRNA vaccines were losing some of their effectiveness against infection, although their efficiency against hospitalization was mostly the same. Last month, the F.D.A. licensed a booster of the Pfizer-BioNTech vaccine for particular populations at high danger from Covid-19; an advisory recommended a booster shot of Moderna’s vaccine on Thursday for the exact same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine utilizes a modified adenovirus to deliver its instructions to human cells, and that distinction is shown in how the vaccines are now carrying out. The Johnson & & Johnson vaccine began with a lower efficacy than the mRNA vaccines, however it has disappointed much modification in its effectiveness over time.

How efficient is a single dosage of the Johnson & & Johnson vaccine?
The company’s scientific trials, performed prior to the Delta variant was widespread, discovered that the Johnson & & Johnson vaccine had 72 percent efficacy in general in the United States, lower than the roughly 95 percent efficacy of the Pfizer and Moderna vaccines.

Here’s a more detailed look.
John Moore, a virologist at Weill Cornell Medicine. What do we understand about the benefits of a 2nd dose?
Recently, Johnson & & Johnson brought out research studies that it declares show that a booster shot of its vaccine will help protect individuals versus Covid-19. It will raise the efficiency of the vaccine overall, the business argues, and be specifically beneficial versus brand-new versions. However regulators have been vital of the company’s information.
Last month, the business revealed the outcomes of a clinical trial that found that two doses of the vaccine, given two months apart, have 94 percent effectiveness in the United States versus moderate to extreme illness, compared with 74 percent effectiveness after a single shot.
Internationally, however, the outcomes were less persuading. Worldwide, the effectiveness of a second dose of the vaccine was 74 percent, up from 66 percent after one shot. And the statistical unpredictabilities around those quotes make it difficult to identify simply just how much better two doses are than one.

Why didn’t they advise an mRNA booster rather of another Johnson & & Johnson shot?
The F.D.A. panel voted only on whether to advise a 2nd Johnson & & Johnson shot on Friday.
Some researchers have actually suggested that mixing and matching vaccines may provide much better protection than getting two dosages of the exact same shot.

What takes place next?
The F.D.A. will review the panel’s recommendation and release a final decision, which might come within a couple of days.
Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own suggestion on Johnson & & Johnson boosters. Its members will decide whether to recommend the chance ats all, in addition to who ought to be eligible.
The C.D.C.’s director, Dr. Rochelle P. Walensky, will then provide the company’s formal guidelines on boosters. These standards are extremely prominent for physicians, pharmacies and healthcare companies.
What should I do in the meantime?
In the meantime, stand by. No booster has yet been licensed for Johnson & & Johnson receivers– the process is still underway.
“I imagine by this time next week, the federal government’s health professionals will have made a recommendation to the American individuals about what they must do,” Dr. Moore said.
It is possible that regulators will license a 2nd Johnson & & Johnson shot before they authorize mRNA boosters for J.&& J. receivers. If that occurs, people who got the Johnson & & Johnson shot will be “on the horns of an issue,” said Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine professional at Vanderbilt University.
People should speak with their medical professionals about whether it makes sense to get a Johnson & & Johnson booster as quickly as it is authorized or wait for a possible mRNA booster, Dr. Schaffner said.
“A lot depends upon where you are and who you are,” he said. Individuals who are at high risk for serious disease and reside in places where the infection is rising may not wish to wait, he stated.

Researchers found that Johnson & & Johnson receivers who received a Moderna booster experienced a 76-fold boost in their antibody levels, compared with a fourfold boost after a second Johnson & & Johnson dosage. A Pfizer booster prompted a 35-fold increase in antibodies.
“To me that data looked quite strong,” stated Dr. Moore, who was not associated with the research.
The F.D.A. has not yet arranged a main vote on whether to advise mRNA boosters for Johnson & & Johnson recipients.
“We have not examined those data in detail,” Dr. Peter Marks, the F.D.A.’s leading vaccine regulator, stated on Friday.
The agency may authorize an mRNA booster for Johnson & & Johnson receivers in the future, he stated, although he did not supply any more information about the timing of such a choice.
At Friday’s meeting, Dr. Ofer Levy, director of the Precision Vaccines Program at Boston Children’s Hospital and a member of the advisory committee, encouraged regulators to move promptly, keeping in mind that lots of Johnson & & Johnson recipients had already looked for unauthorized mRNA boosters on their own.
“In the genuine world, all these sort of mixes or additional boosters are currently occurring, so I believe it’s a matter of some seriousness for F.D.A. to assist figure out what is undoubtedly a tough and complicated scenario,” he said.
What occurs next?
The F.D.A. will evaluate the panel’s recommendation and issue a decision, which could come within a few days.
Next week, a vaccine advisory panel to the Centers for Disease Control and Prevention will make its own suggestion on Johnson & & Johnson boosters. Its members will choose whether to advise the chance ats all, as well as who should be qualified.
The C.D.C.’s director, Dr. Rochelle P. Walensky, will then issue the agency’s formal guidelines on boosters. These standards are highly influential for physicians, drug stores and healthcare service providers.
What should I carry out in the meantime?
For now, stand by. No booster has actually yet been licensed for Johnson & & Johnson receivers– the procedure is still underway.
“I picture by this time next week, the federal government’s health specialists will have made a suggestion to the American people about what they should do,” Dr. Moore said.
It is possible that regulators will license a second Johnson & & Johnson shot before they authorize mRNA boosters for J.&& J. receivers. If that happens, individuals who got the Johnson & & Johnson shot will be “on the horns of an issue,” stated Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine specialist at Vanderbilt University.
People ought to consult with their physicians about whether it makes good sense to get a Johnson & & Johnson booster as quickly as it is authorized or await a possible mRNA booster, Dr. Schaffner said.
“A lot depends on where you are and who you are,” he stated. Individuals who are at high danger for major disease and live in locations where the virus is rising may not want to wait, he stated.
