Tracking the development of a coronavirus vaccine booster without a scorecard can be difficult.
This week, the Food and Drug Administration’s Expert Advisory Board will vote on whether to recommend booster vaccinations for two of the three vaccines used in the United States, Moderna and Johnson & Johnson, to recipients of each vaccine. ..
The agency has already approved a third booster shot from Pfizer-BioNTech for the specific group that was first vaccinated, including adults aged 65 and over and residents of long-term care facilities. A third dose of Pfizer-BioNTech and Moderna vaccines is also allowed for some people with a weakened immune system who may not be fully protected from the original two doses.
All three vaccines initially provide very strong protection against Covid-19 infection, serious illness, and death. Booster propulsion, while its protection remains strong against serious illness and death, declines somewhat over time, allowing for more breakthrough infections of particularly contagious delta mutants. It comes from studies that suggest that it may be. This decline tends to be most pronounced in the elderly and people with certain underlying illnesses.
This is an overview of the booster shot status of the three vaccines available in the United States.
What you get: A third full dose at least 6 months after the second.
Where it stands in the United States: It is now available to many people. The FDA approves third shots for people over the age of 65, people with certain medical conditions, and others at high risk due to work or place of residence. (Some people with weakened immunity can get a third injection two to a month later.) Authorities decide whether to allow others to boost their immunity. The decision has been postponed.
Where it stands elsewhere: Israel and several other countries have extensive control over Pfizer-BioNTech booster shots.
What science says: The Pfizer-BioNTech vaccine was the first to receive full approval in the United States (ages 16+), was first approved by some children (ages 12-15), and was first approved by boosters. The available data on its safety and effectiveness are particularly robust. Some studies suggest that the vaccine may become less effective over time than the modana vaccine.
What you get: Half dose, at least 6 months after the second full dose.
Where it stands in the United States: We are currently awaiting approval as a booster for the same population who are eligible for Pfizer boosters. (Some people with weakened immunity can take a third dose one month after the second dose.)
Where it stands elsewhere: Some countries offer or will soon offer Moderna booster shots.
What science says: Some studies suggest that the effectiveness of the Moderna vaccine is not reduced compared to the other two vaccines available in the United States. This may mean that Moderna recipients are less likely to need to get boosters. With that in mind, the FDA staff’s report took a neutral position on Moderna’s booster shot application.
What you need to know about Covid-19 booster shots
The FDA has approved booster shots for a specific group of people who received a second dose of the Pfizer-BioNTech vaccine at least six months ago. The group includes: Pfizer recipients over the age of 65 or living in a long-term care facility. Adults at high risk for severe Covid-19 due to underlying illness. Healthcare workers and other people whose work puts them at risk. People with weakened immunity are eligible for a third dose of Pfizer or Moderna four weeks after the second injection.
Regulators have not yet approved booster shots for Moderna and Johnson & Johnson vaccine recipients, but the FDA Panel will meet to weigh booster shots for adult recipients of Moderna and Johnson & Johnson vaccines.
The CDC states that the conditions covered by booster shots include: High blood pressure and heart disease. Diabetes or obesity; cancer or blood disorders; weakened immunity; chronic lung, kidney or liver disease; dementia and certain disorders. Pregnant women, current and former smokers are also eligible.
The FDA has approved boosters for workers who work at high risk of being exposed to potentially infected people. According to the CDC, this group includes: Education workers; Food and agriculture workers; Manufacturing workers; Correction workers; US Postal Service workers; Public transport workers; Grocery shop workers.
Not recommended. For now, Pfizer Vaccine Recipients are advised to take Pfizer Booster Shots. Moderna and Johnson & Johnson recipients will have to wait until booster doses from these manufacturers are approved.
Yes. According to the CDC, the Covid vaccine may be given at any time, and many pharmacies allow flu vaccinations to be scheduled at the same time as boosters.
Johnson & Johnson
What you get: Second dose, probably 6 months after the first dose.
Where it stands in the United States: Waiting for approval. A report from FDA staff found that the data the company submitted with the application had serious flaws, but it was not clear if that would delay the decision.
Where it stands elsewhere: No country has yet recommended a second dose of Johnson & Johnson vaccine.
What science says: Although the Johnson & Johnson vaccine is not as powerful as the Pfizer or Moderna double dose vaccine, there has long been interest in boost immunization of Johnson & Johnson recipients because it provides strong initial protection after a single dose.
