COVID-19 vaccines: Understanding the need for boosters

With the COVID-19 pandemic still affecting communities worldwide, the need for vaccines remains high. Pfizer, Moderna, and Johnson & Johnson are some of the most widely recognized COVID-19 vaccine manufacturers, and their vaccines have been available to the public for some time now. However, as new COVID-19 variants continue to emerge, there is a need for vaccine boosters to ensure that people remain protected against the virus. Here’s what you need to know about COVID-19 vaccine boosters:

What are COVID-19 vaccine boosters?

Vaccine boosters are additional doses of a vaccine that are given after the initial doses to provide ongoing protection against the targeted disease. In the case of COVID-19 vaccines, boosters are necessary due to the emergence of new variants of the virus, which may reduce the effectiveness of the initial vaccine dose. In addition, some studies have shown that vaccine immunity may wane over time, making booster shots necessary to maintain protection.

What are Pfizer, Moderna, and Johnson & Johnson saying about booster shots?

Pfizer and Moderna have both indicated that booster shots may be necessary to maintain immunity against COVID-19, particularly in light of new variants of the virus. In August 2021, the US Food and Drug Administration (FDA) authorized booster shots for people who have received the Pfizer-BioNTech or Moderna vaccines and are moderately or severely immunocompromised. Johnson & Johnson has also announced plans to offer a booster shot of its vaccine, pending FDA authorization.
