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 grownups who had gotten their first chance at least 2 months prior.
If the F.D.A., which normally follows the panel’s suggestions, authorizes a second shot, the 15 million Americans who got the Johnson & & Johnson vaccine might soon begin getting boosters.
On Thursday, the same F.D.A. committee voted to license boosters for Americans who received the Moderna vaccine. The additional shots have actually currently been licensed for Pfizer-BioNTech receivers.
Johnson & & Johnson says that a second dosage of its shot boosts the levels of antibodies against the coronavirus and is more efficient at preventing Covid-19.
“We wish to offer optimal protection versus Covid,” Dr. Penny Heaton, international restorative area head for vaccines at Johnson & & Johnson, said at Friday’s meeting.
F.D.A. staff have expressed doubts about the quality of the research study. And a booster dose of one of the mRNA vaccines, either the Pfizer or Moderna shot, may offer even higher defense, initial data suggest.
Here are responses to some common concerns.
Why didn’t authorities suggest boosters for people who got the Johnson & & Johnson vaccine earlier?
All of the vaccines authorized in the United States supply strong protection versus severe disease and death from Covid-19.
Over the summer, specialists grew worried that mRNA vaccines were losing some of their efficiency versus infection, although their efficiency versus hospitalization was mostly unchanged. Last month, the F.D.A. licensed a booster of the Pfizer-BioNTech vaccine for particular populations at high risk from Covid-19; an advisory suggested a booster shot of Moderna’s vaccine on Thursday for the exact same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine uses a modified adenovirus to provide its instructions to human cells, and that distinction is shown in how the vaccines are now performing. The Johnson & & Johnson vaccine started with a lower effectiveness than the mRNA vaccines, however it has actually disappointed much change in its effectiveness with time. Studies of antibody levels have found little modification over 8 months.
Information on the Johnson & & Johnson vaccine has been slower in coming, in part because vaccine was not authorized till completion of February, 2 months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were temporarily paused while health authorities examined reports that a very little number of individuals had actually developed an uncommon blood-clotting condition after getting the vaccine.
How effective is a single dose of the Johnson & & Johnson vaccine?
The business’s medical trials, conducted before the Delta version was widespread, discovered that the Johnson & & Johnson vaccine had 72 percent efficacy overall in the United States, lower than the approximately 95 percent efficacy of the Pfizer and Moderna vaccines. The vaccine’s security versus extreme or crucial disease was greater, at 85 percent worldwide.
It is tough to make direct contrasts between the vaccines, which were checked in different areas and at various times.
All of the offered vaccines appear to lose some effectiveness versus Delta, which may have the ability to evade a few of the immune system’s antibodies. However data suggests that the Johnson & & Johnson vaccine holds up well versus the variation.
Preliminary arise from medical trials of almost 500,000 healthcare workers in South Africa suggested that a single dose of the vaccine had efficacy of approximately 96 percent against death and 71 percent versus hospitalization from infections brought on by Delta.
It was “a really big analysis and really clear results revealing that the single-shot J.&& J. vaccine supplied significant security against the Delta variation,” Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in Boston, said in August. Dr. Barouch has actually conducted research studies for Johnson & & Johnson but was not included in the South Africa trial.
The company also revealed results from another real-world research study, carried out in the United States, last month. The study, which has not yet been examined by experts, found that the vaccine’s effectiveness remained steady at 79 percent through July, suggesting that it continued to offer excellent security versus Delta. It was 81 percent efficient at preventing hospitalizations.
Oct. 15: This post has been updated to show brand-new research about the Johnson & & Johnson vaccine and brand-new regulative 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 boost after a 2nd Johnson & Johnson dose. 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 swiftly, keeping in mind that lots of Johnson & Johnson recipients had actually currently 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 license before they authorize mRNA boosters for J. & License recipients. People must 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 said.
Updated Nov. 15, 2021, 9:17 a.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 performed studies that
it claims show that a booster shot of its vaccine will assist secure people against Covid-19. It will raise the effectiveness of the vaccine in general, the company argues, and be specifically beneficial against brand-new variations. Regulators have been important of the business’s data. Last month, the company revealed the outcomes of a scientific trial that found that 2 doses of the vaccine, offered 2 months apart, have 94 percent effectiveness in the United States versus moderate to extreme illness, compared to 74 percent effectiveness
after a single shot. Globally, nevertheless, the results were less convincing. Worldwide, the effectiveness of a 2nd dose of the vaccine was 74 percent, up from 66 percent after one shot. And the statistical uncertainties around those estimates make it difficult to identify simply just how much better two dosages are than one. On the other hand, it appears that a second dose does enhance security against serious illness, with an approximated effectiveness of 100 percent. Regulators have actually slammed the study’s brief follow-up duration. Why didn’t they recommend an mRNA booster instead of another Johnson & Johnson shot
? The F.D.A. panel voted just on whether to suggest a 2nd Johnson & Johnson shot on Friday. However some researchers have suggested that mixing and matching vaccines may
provide much better protection than getting two doses of the exact same shot.

And initial data from a study performed by the National Institutes of Health suggests
that the method has pledge. The study, which has actually not yet been reviewed by professionals, involved 9 different groups
of individuals, of approximately 50 individuals each. Each group got a various vaccine and booster mix; some individuals got a booster dosage of the exact same brand as the original vaccine, while others changed to a various brand name for their booster. Scientists found that Johnson & Johnson receivers who got a Moderna booster experienced a 76-fold increase in their antibody levels, compared with a fourfold boost after a 2nd Johnson & Johnson dosage. A Pfizer booster triggered a 35-fold boost in antibodies.” To me that data looked pretty solid,”said Dr. Moore, who was not involved in the research study. The F.D.A. has actually not yet arranged a main vote on whether to suggest mRNA boosters for Johnson & Johnson recipients.
“We have actually not reviewed those information in detail,”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 offer anymore info & about the timing of such a choice. 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, motivated regulators to move swiftly, keeping in mind that lots of Johnson & Johnson receivers had already sought out unauthorized mRNA boosters by themselves.”In the real world, all these sort of mixes or additional boosters are currently occurring, so I believe it’s a matter of some urgency for F.D.A. to help arrange out what is undoubtedly a complicated and tough situation,”he stated. What takes place & next? The F.D.A. will review
the panel’s suggestion and provide a 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 advise the chance ats all, along with who must be qualified. The C.D.C.’s director, Dr. Rochelle P. Walensky, will then release the company’s formal standards on boosters. These standards are highly influential for physicians, drug stores and healthcare providers. What should I perform in the meantime? In the meantime, sit tight. No booster has actually yet been licensed
for Johnson & Johnson recipients– the process is still underway.”I envision by this time next week, the federal government’s health professionals will have made a recommendation to the American people about what they need to do,”Dr. Moore said. However it is possible
that regulators will license a 2nd Johnson & Johnson shot prior to they license mRNA boosters for J. & J. recipients. If that takes place, people who got the Johnson & Johnson shot
will be”on the horns of a dilemma,”stated Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine expert at Vanderbilt University. People must seek advice from with their doctors about whether it makes sense to get a Johnson & Johnson booster as quickly as it is licensed or wait on a possible mRNA booster, Dr. Schaffner said.”A lot depends on where you are and who you are,”he said. People who are at high danger for major disease and live in places where the virus
is rising might not wish to wait, he said

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.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine uses a modified adenovirus to provide its instructions to human cells, and that difference 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 disappointed much change in its effectiveness over time. Similarly, studies of antibody levels have actually discovered little modification over 8 months.
Data on the Johnson & & Johnson vaccine has been slower in coming, in part because vaccine was not authorized until the end of February, 2 months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were briefly paused while health authorities examined reports that an extremely small number of people had developed an unusual blood-clotting condition after getting the vaccine.
How effective is a single dosage of the Johnson & & Johnson vaccine?
The business’s clinical trials, performed prior to the Delta version was widespread, discovered that the Johnson & & Johnson vaccine had 72 percent efficacy overall in the United States, lower than the approximately 95 percent effectiveness of the Pfizer and Moderna vaccines. The vaccine’s protection against extreme or critical disease was higher, at 85 percent worldwide.
Nevertheless, it is hard to make direct comparisons between the vaccines, which were tested in different locations and at different times.
All of the offered vaccines appear to lose some effectiveness versus Delta, which might be able to dodge a few of the body immune system’s antibodies. But information suggests that the Johnson & & Johnson vaccine holds up well versus the version.
Initial arise from medical trials of nearly 500,000 healthcare employees in South Africa suggested that a single dose of the vaccine had efficacy of up to 96 percent versus death and 71 percent versus hospitalization from infections triggered by Delta.
It was “a really big analysis and extremely clear results revealing that the single-shot J.&& J. vaccine provided considerable protection against the Delta variation,” Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in Boston, said in August. Dr. Barouch has conducted studies for Johnson & & Johnson but was not associated with the South Africa trial.
The business likewise announced outcomes from another real-world study, carried out in the United States, last month. The research study, which has actually not yet been evaluated by specialists, discovered that the vaccine’s efficiency stayed stable at 79 percent through July, recommending that it continued to supply good security against Delta. It was 81 percent effective at avoiding hospitalizations.
Oct. 15: This post has actually been upgraded to reflect brand-new research about the Johnson & & Johnson vaccine and new regulative advancements.
The Food and Drug Administration’s vaccine advisory panel all voted on Friday to suggest a 2nd dosage of the single-shot Johnson & & Johnson vaccine for grownups who had actually gotten their very first chance at least 2 months prior.
If the F.D.A., which generally follows the panel’s recommendations, licenses a second shot, the 15 million Americans who got the Johnson & & Johnson vaccine could soon begin receiving boosters.
On Thursday, the exact same F.D.A. committee voted to license boosters for Americans who received the Moderna vaccine. The extra shots have actually already been authorized for Pfizer-BioNTech recipients.
Johnson & & Johnson states that a second dose of its shot improves the levels of antibodies against the coronavirus and is more reliable at preventing Covid-19.
“We want to provide ideal protection versus Covid,” Dr. Penny Heaton, global therapeutic location head for vaccines at Johnson & & Johnson, stated at Friday’s conference.
However F.D.A. personnel have actually expressed doubts about the quality of the research. And a booster dosage of one of the mRNA vaccines, either the Pfizer or Moderna shot, may use even greater defense, preliminary data recommend.
Here are responses to some typical questions.
Why didn’t authorities advise boosters for people who got the Johnson & & Johnson vaccine quicker?
All of the vaccines licensed in the United States supply strong protection versus extreme illness and death from Covid-19.
Over the summer season, specialists grew worried that mRNA vaccines were losing a few of their efficiency versus infection, although their efficiency against hospitalization was mostly unchanged. 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 advised a booster shot of Moderna’s vaccine on Thursday for the same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine utilizes a modified adenovirus to deliver its instructions to human cells, and that difference is reflected in how the vaccines are now carrying out. The Johnson & & Johnson vaccine started with a lower effectiveness than the mRNA vaccines, however it has actually disappointed much change in its efficiency gradually. Similarly, research studies of antibody levels have actually found 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 authorized up until completion of February, 2 months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were briefly paused while health officials investigated reports that an extremely little number of individuals had established a rare blood-clotting condition after getting the vaccine.
How reliable is a single dosage of the Johnson & & Johnson vaccine?
The company’s medical trials, carried out before the Delta version was widespread, found that the Johnson & & Johnson vaccine had 72 percent effectiveness overall in the United States, lower than the roughly 95 percent efficacy of the Pfizer and Moderna vaccines. The vaccine’s security against severe or critical illness was higher, at 85 percent worldwide.
It is hard to make direct comparisons in between the vaccines, which were evaluated in different locations and at various times.
All of the offered vaccines appear to lose some effectiveness against Delta, which may have the ability to dodge a few of the immune system’s antibodies. Data recommends that the Johnson & & Johnson vaccine holds up well against the variant.
Initial arise from scientific trials of nearly 500,000 health care workers in South Africa suggested that a single dosage of the vaccine had efficacy of as much as 96 percent versus death and 71 percent versus hospitalization from infections brought on by Delta.
It was “a very large analysis and extremely clear outcomes revealing that the single-shot J.&& J. vaccine provided significant protection versus the Delta variation,” Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in Boston, said in August. Dr. Barouch has actually carried out research studies for Johnson & & Johnson however was not associated with the South Africa trial.
The business also revealed results from another real-world research 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 steady at 79 percent through July, suggesting that it continued to offer excellent protection versus Delta. It was 81 percent reliable at avoiding hospitalizations.
it declares show that a booster shot of its vaccine will help protect people versus Covid-19. It will raise the efficiency of the vaccine overall, the business argues, and be especially useful against new versions. But regulators have been crucial of the business’s data. Last month, the company revealed the outcomes of a medical trial that discovered that two dosages of the vaccine, provided two months apart, have 94 percent efficacy in the United States versus mild to serious disease, compared to 74 percent efficacy
after a single shot. Globally, nevertheless, the outcomes were less convincing. Worldwide, the effectiveness of a 2nd dosage of the vaccine was 74 percent, up from 66 percent after one shot. And the statistical uncertainties around those quotes make it hard to determine simply just how much better two dosages are than one. On the other hand, it appears that a 2nd dosage does enhance defense against severe illness, with an approximated efficacy of 100 percent. Regulators have actually slammed the research 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 just on whether to recommend a 2nd Johnson & Johnson shot on Friday. Some researchers have recommended that mixing and matching vaccines may
supply better defense than getting 2 dosages of the very same shot.
And preliminary information from a study performed by the National Institutes of Health recommends
that the approach has promise. The study, which has not yet been evaluated by specialists, included nine various groups
of individuals, of roughly 50 people each. Each group got a different vaccine and booster mix; some individuals got a booster dosage of the exact same brand name as the initial vaccine, while others switched to a various brand for their booster. Researchers found 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. A Pfizer booster prompted a 35-fold boost in antibodies.” To me that information looked quite solid,”stated Dr. Moore, who was not included in the research. The F.D.A. has not yet set up a main vote on whether to recommend mRNA boosters for Johnson & Johnson receivers.
“We have actually not evaluated those information in information,”Dr. Peter Marks, the F.D.A.’s leading vaccine regulator, said on Friday. The agency might authorize an mRNA booster for Johnson & Johnson receivers in the future, he stated, although he
did not supply any more details & 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, encouraged regulators to move swiftly, noting that numerous Johnson & Johnson receivers had currently looked for unapproved mRNA boosters by themselves.”In the genuine world, all these sort of mixes or extra boosters are currently taking place, so I believe it’s a matter of some urgency for F.D.A. to assist arrange out what is undoubtedly a complicated and difficult situation,”he stated. What takes place & next? The F.D.A. will evaluate
the panel’s recommendation and issue a last 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 recommendation on Johnson & Johnson boosters. Its members will decide whether to advise the chance ats all, as well as who must be eligible. The C.D.C.’s director, Dr. Rochelle P. Walensky, will then provide the company’s official guidelines on boosters. These standards are highly prominent for physicians, pharmacies and healthcare providers. What should I perform in the meantime? For now, sit tight. No booster has yet been licensed
for Johnson & Johnson receivers– the process is still underway.”I envision by this time next week, the federal government’s health professionals will have made a recommendation to the American people about what they must do,”Dr. Moore said. It is possible
that regulators will authorize a second Johnson & Johnson shot before 2nd authorize mRNA boosters for Prior to & J. recipients. If that occurs, people who got the Johnson & Johnson shot
will be”on the horns of a predicament,”said Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases and a vaccine expert at Vanderbilt University. Individuals 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.”A lot depends upon where you are and who you are,”he stated. Individuals who are at high threat for severe illness and reside in locations where the virus
is rising might 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 increase after a second Johnson & Johnson dose. 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, noting that many Johnson & Johnson receivers had currently 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 recommendation on Johnson & Johnson boosters. It is possible

“We desire to offer optimum defense versus Covid,” Dr. Penny Heaton, worldwide therapeutic area head for vaccines at Johnson & & Johnson, stated at Friday’s conference.
But F.D.A. personnel have expressed doubts about the quality of the research study. And a booster dosage of one of the mRNA vaccines, either the Pfizer or Moderna shot, might use even higher protection, initial data recommend.
Here are answers to some typical questions.
Why didn’t officials recommend boosters for people who got the Johnson & & Johnson vaccine faster?
All of the vaccines authorized in the United States offer strong defense versus extreme illness and death from Covid-19.
Over the summertime, experts grew worried that mRNA vaccines were losing some of their efficiency against infection, although their effectiveness 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 risk from Covid-19; an advisory advised a booster shot of Moderna’s vaccine on Thursday for the very same populations.
Unlike Moderna and Pfizer-BioNTech, the Johnson & & Johnson vaccine utilizes a customized adenovirus to deliver its directions 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 actually disappointed much change in its efficiency over time. Likewise, studies of antibody levels have actually found little modification over eight months.
Data on the Johnson & & Johnson vaccine has actually been slower in coming, in part since vaccine was not authorized until the end of February, two months after the mRNA vaccines. In addition, Johnson & & Johnson vaccinations were briefly stopped briefly while health authorities examined reports that a really little number of people had actually developed an unusual blood-clotting condition after receiving the vaccine.
How efficient is a single dosage of the Johnson & & Johnson vaccine?
The company’s clinical trials, carried out prior to the Delta variation was prevalent, discovered that the Johnson & & Johnson vaccine had 72 percent effectiveness overall in the United States, lower than the approximately 95 percent efficacy of the Pfizer and Moderna vaccines. The vaccine’s defense against important or severe disease was greater, at 85 percent worldwide.
Nevertheless, it is difficult to make direct contrasts in between the vaccines, which were evaluated in different places and at different times.
All of the readily available vaccines appear to lose some efficiency against Delta, which might be able to evade some of the body immune system’s antibodies. But data recommends that the Johnson & & Johnson vaccine holds up well against the variation.

Oct. 15: This short article has been updated to show brand-new research study about the Johnson & & Johnson vaccine and brand-new regulative developments.
Scientists discovered that Johnson & Johnson receivers who received a Moderna booster experienced a 76-fold increase in their antibody levels, compared with a fourfold boost after a second 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 promptly, noting that lots of Johnson & Johnson recipients had actually already sought out unauthorized mRNA boosters on their own.

Updated Nov. 14, 2021, 6:49 p.m. ET”These vaccines are working,”stated John Moore, a virologist at Weill Cornell Medicine. What do we know about the advantages of a 2nd dose? Just recently, Johnson & Johnson performed studies that
it declares program that a booster shot of its vaccine will assist safeguard individuals versus Covid-19. It will raise the effectiveness of the vaccine overall, the company argues, and be particularly beneficial against brand-new variants. Regulators have been vital of the business’s information. Last month, the company announced the outcomes of a clinical trial that discovered that 2 dosages of the vaccine, given 2 months apart, have 94 percent efficacy in the United States against mild to serious disease, compared with 74 percent effectiveness
after a single shot. Internationally, nevertheless, the outcomes were less convincing. Worldwide, the effectiveness of a second dosage of the vaccine was 74 percent, up from 66 percent after one shot. And the analytical unpredictabilities around those price quotes make it difficult to determine simply just how much better 2 dosages are than one. On the other hand, it appears that a 2nd dosage does improve protection versus extreme illness, with an estimated efficacy of 100 percent. Regulators have actually slammed the study’s short follow-up duration. Why didn’t they recommend an mRNA booster instead of another Johnson & Johnson shot
? The F.D.A. panel voted only on whether to suggest a second Johnson & Johnson shot on Friday. Some scientists have actually suggested that blending and matching vaccines may
supply better defense than getting two doses of the exact same shot.

And preliminary information from a research study performed by the National Institutes of Health suggests
that the technique has guarantee. The study, which has actually not yet been examined by specialists, involved 9 different groups
of participants, of roughly 50 individuals each. Each group got a various vaccine and booster mix; some people received a booster dose of the same brand name as the original vaccine, while others changed to a different brand name for their booster. Researchers found that Johnson & Johnson receivers who got a Moderna booster experienced a 76-fold increase in their antibody levels, compared with a fourfold increase after a second Johnson & Johnson dose. A Pfizer booster triggered a 35-fold increase in antibodies.” To me that data looked pretty strong,”said Dr. Moore, who was not associated with the research. The F.D.A. has actually not yet set up an official vote on whether to suggest mRNA boosters for Johnson & Johnson recipients.

the panel’s suggestion and provide a decision, which could 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 shots at all, in addition to who must be eligible. The C.D.C.’s director, Dr. Rochelle P.
