The approval process for Covid-19 vaccines can be confusing. Here’s a look at our stance on Covid-19 boosters in the US today:


In September, the United States Food and Drug Administration and the United States Centers and Disease Control and Prevention approved boosters of the Pfizer / BioNTech Covid-19 vaccine for adults 65 years of age and older, high-risk adults of severe Covid-19 and frequently exposed adults. to coronavirus through their work. These booster shots were only allowed for people who had already received the Pfizer vaccine at least six months earlier.

U.S. Centers for Disease Control and Prevention director Dr. Rochelle Walensky on Wednesday endorsed the blended approach to boosters, meaning the Pfizer / BioNTech booster can be taken by those who may be eligible but are fully vaccinated with Moderna or Johnson & Johnson Coronavirus Vaccines.

Additionally, next week, FDA vaccine advisers are due to meet next week to review Pfizer’s request to authorize its vaccine for children aged 5 to 11.


The FDA on Wednesday granted emergency use authorization for a half-dose of Moderna’s vaccine as a booster for people fully vaccinated at least six months ago who are also at least 65 years of age, or who are at least 18 years old and at high risk of severe Covid-19 or have frequent institutional or occupational exposure to the virus.

Walensky on Thursday approved a booster dose recommendation for the Moderna vaccine.

Johnson & Johnson

On Wednesday, the FDA cleared booster doses of the Johnson & Johnson vaccine for anyone who received it at least two months ago. The J&J vaccine authorized only for those 18 years of age and over.

The company announced last month that a two-dose version of the vaccine offers 94% protection against symptomatic infections.

Walensky on Thursday approved a booster dose recommendation for the Johnson & Johnson vaccines.

Mix and match boosters

The FDA said one of the three licensed vaccines could be used as a booster in a “mix-and-match” approach.

Dr Peter Marks, director of the vaccines arm of the FDA, Center for Biologics Evaluation and Research, said being able to use any licensed vaccine as a booster will make it easier for people.

The FDA said it decided to allow mixed boosters after researchers from the National Institutes of Health presented their findings last week to its vaccine advisers. Although the results were limited, they made it clear that mixing the different vaccines was safe.

Walensky also endorsed the blended booster approach, saying eligible people could choose any vaccine they wanted as a booster.
