If you’ve recently had COVID-19 but haven’t yet received your booster shot - should you run to your local vaccination site to get it? Elliot Frank, M.D., an infectious disease specialist and medical director of quality and outcomes at Jersey Shore University Medical Center, shares some guidance on when is the best time to get your booster.

When You Should Get Your Shot

According to the Centers for Disease Control and Prevention (CDC), the official guidance says you should wait until you’ve finished isolating and your symptoms have improved. This can mean that you can get vaccinated or boosted as soon as 10 days after your first day of symptoms or a positive viral test.

You do not have to wait 90 days to get your vaccine or booster, unless you received a monoclonal antibody treatment. 

Why Should You Get A Booster Even If You’ve Had COVID

Emerging evidence shows that getting vaccinated or boosted after you recover from COVID-19 infection provides added protection to your immune system. One study showed that, for people who already had COVID-19, those who do not get vaccinated after their recovery are more than 2 times as likely to get COVID-19 again than those who get fully vaccinated after their recovery.

A recent report from the UK also showed Omicron was associated with a 5.4-fold higher risk of reinfection compared with Delta. This suggests that there could be relatively low remaining levels of immunity from prior infections.

Our experts recently shared three simple reasons why it’s important to get a booster shot right now.
