Tracking coronavirus vaccine development may be tough booster without scorecard.
Panel of Expert Advisors from the Food and Drug Administration Voted Thursday to recommend booster shots for multiple recipients of the Moderna coronavirus vaccine, and is due to meet on Friday to consider boosters for recipients johnson and johnsonThe commentary
The agency has already authorized booster shots of other Vaccines in use in the United States from Pfizer-BioNtech, for some groups that initially received that vaccine. A third dose of Pfizer-BioEntech and Moderna Vaccines has also been authorized for some people with weakened immune systems who may not have received full protection from the original two doses.
All three vaccines initially provide very strong protection against infection, serious illness, and death from Covid-19. The impetus for the booster comes from studies suggesting that while protection against serious illness and death remains robust, this may decrease somewhat over time and the greater success of the highly infectious Delta variant in particular. may allow infection. The decline is most pronounced in older people and those with certain underlying medical conditions.
Here is a detailed description of the booster-shot situation for the three vaccines available in the United States.
what do you get: the third full dose, at least six months after your second.
Where does it stand in America: Now available to many people. FDA authorizes third shot For people over 65, people with certain medical conditions and some others who are at higher risk because they work or live. (some immunocompromised people can take a third shot a month after their second.) The agency has deferred a decision about authorizing the boosters for others.
Where else does it stand: Israel and some other countries are widely administering Pfizer-BioNTech booster shots.
What Science Says: The Pfizer-BioNTech vaccine was the first to receive full approval in the United States (for those 16 and older), the first to be authorized for some children (those 12 to 15), and the first to be authorized for a booster. ; The available data on its safety and effectiveness are particularly strong. Some studies suggest that the vaccine may decline in effectiveness over time Little more than Moderna Vaccine.
what do you get: half dose, for at least six months after your second full dose.
Where does it stand in America: An FDA advisory panel voted Thursday to recommend the Moderna booster for the same population groups that are now eligible for the Pfizer booster. The panel’s vote is non-binding, but its recommendations are generally followed by the FDA (some immunocompromised people). can receive a full third dose A month after their second.)
Where else does it stand: Some countries are already offering Moderna booster shots or are planning to do so soon.
What Science Says: Some studies suggest that Moderna Vaccine has a lower effectiveness than the other two vaccines available in the United States. This could mean that Modern recipients have less need to receive boosters. bearing this in mind, an FDA staff report took a neutral stance On Moderna’s booster-shot application.
What to know about Covid-19 booster shots
FDA Authorized booster shots For a select group of people who received a second dose of the Pfizer-BioNTech vaccine at least six months ago. That group includes: Pfizer recipients who are 65 years of age or older or who live in long-term care facilities; Adults who are at high risk of severe Covid-19 because of an underlying medical condition; Health care workers and others whose jobs put them at risk. people with weak immune system Four weeks after the second shot are eligible for a third dose of Pfizer or Moderna.
The CDC states that conditions that qualify a person for a booster shot include: high blood pressure and heart disease; diabetes or obesity; cancer or blood disorder; weakened immune system; chronic lung, kidney or liver disease; Dementia and some disabilities. Pregnant women and current and former smokers are also eligible.
The FDA authorizes boosters for workers whose jobs put them at high risk of coming into contact with potentially infectious people. The CDC says the group includes: emergency medical workers; education worker; food and agricultural workers; construction workers; reform worker; US Postal Service employees; public transport workers; Grocery store workers.
It is not recommended. For now, Pfizer vaccine recipients are advised to get a Pfizer booster shot, and Moderna and Johnson & Johnson recipients should wait until a booster dose is approved from those manufacturers.
Yes. The CDC says the Covid vaccine can be administered regardless of the timing of other vaccines, and many pharmacy sites are allowing people to schedule the flu shot at the same time as a booster dose.

what do you get: Second dose, probably six months after the initial dose.
Where does it stand in America: Awaiting authorization. The FDA advisory panel meets on Friday to decide on a recommendation. One FDA staff report Significant deficiencies were found in the data that the company submitted with its application, but it was not clear whether this would delay the decision.
Where else does it stand: No country has yet recommended a second dose of Johnson & Johnson vaccine.
What Science Says: Johnson & Johnson vaccine gives strong initial protection after a single dose, however not strong enough In the form of Pfizer or Moderna two-dose vaccines, therefore, there has long been interest in boosters for Johnson & Johnson recipients.
