As the country continues to struggle with the COVID-19 pandemic, medical experts and scientists are pushing for booster vaccinations to ensure optimal protection against SARS-CoV-2. So far, however, only Pfizer-BioNTech’s vaccine has been approved for the third dose, leaving millions of Americans wondering how long it would take for Moderna and Johnson & Johnson vaccines to be booster approved.

FDA assessment on additional shots

The Food and Drug Administration’s Advisory Committee on Vaccines and Related Biological Products will meet this week to discuss the need for additional doses for those who have received the Moderna and Janssen vaccines in the country. The group will discuss the possible third dose for Moderna recipients on Thursday, and committee members are expected to meet again on Friday to address the need for another dose of the J&J vaccine, according to CNBC.

On the two days of the advisory group’s meeting, data on the safety and effectiveness of the Moderna and Janssen boosters for adults will be discussed. The team’s final decision could take days after the meetings. However, this would not be the end of the road in the advisory process. Once it has passed its verdict, the FDA must turn things over to the Centers for Disease Control and Prevention (CDC).

CDC participation in the approval of boosters

The national health agency will also make its own reflections on the Moderna and J&J vaccines once the FDA completes its assessment. This means recipients of the two vaccines will have to wait weeks before receiving their booster vaccination.

The CDC’s Advisory Committee on Immunization Practices is scheduled to hold advisory meetings on October 20-21. Just like the FDA advisory group this week, the CDC committee members will gather to review the available data and the potential need for booster vaccination for the adult population.

When the FDA and CDC approved the third dose of Pfizer-BioNTech, they made almost similar judgments. Both authorities approved booster vaccinations in adult people at high risk of developing severe COVID-19. The CDC initially did not include people with frequent occupational exposure in its guidelines. CDC director Dr. However, Rochelle Walensky ultimately decided to follow the advice of the FDA under The Conversation.

Updates to Moderna, Janssen Booster Shots

In late September there were reports that the FDA may be considering using half a Moderna vaccine as a booster. Unlike Pfizer’s 30 microgram vaccine dose, Moderna’s vaccination is a 100 microgram dose, leading some medical experts to believe that halving the Moderna dose for the booster would be ideal to reduce the risk of side effects .

Johnson & Johnson, on the other hand, asked the FDA last week to approve their booster for their coronavirus vaccine. At that time, the pharmaceutical company emphasized the need for an appropriate interval based on its internal studies. According to J&J, recipients of the single-dose vaccine should receive the additional vaccination either two months after or six months after their vaccination for optimal immune protection. Between the two, the latter should deliver better results, according to CNN.
