What is the duration of COVID-19 vaccination immunity?

Hank Bernstein, MD: I’m Hank Bernstein, and I’m speaking to you today on behalf of the Children’s Hospital of Philadelphia’s Vaccination Education Center. “How long will COVID-19 vaccination immunity last?” is a question” With so much disease and mortality, COVID vaccines needed to be produced at breakneck speed. We don’t have specific answers about long-term immunity because they’ve only been around for less than a year. It’s also true that we don’t know how much antibody is required for protection, how long the protection lasts, or whether a booster dose will be required.

Yet, there is some really excellent news. COVID vaccination protection appears to be staying longer and longer every day. Individuals appear to be safe for at least six months, and possibly even a little longer. Now, with additional data on the horizon, as experts carefully evaluate the vaccine’s safety and effectiveness, we’re learning more all the time. This is a fantastic scientific feat. The memory cells in our immune system are also important for long-term defense. They are the cells that rapidly expand when exposed to the virus and develop resistance. Also, the type of antibodies, in this case neutralizing antibodies, must develop. When we’re exposed to a virus, these neutralizing antibodies get to work attacking it. Research continue to show good findings, implying that the current COVID-19 vaccinations provide long-lasting immunity. The fact that immunity could last considerably longer than six months is both encouraging and intriguing.

Thank you very much.
