How many doses of COVID-19 vaccine should I receive?

The Pfizer and Moderna vaccine formulations require two doses to be administered 21 days apart. The Moderna vaccine, that was approved for emergency use on December 18, also requires two doses 28 days apart. Both injections are necessary to be fully effective, according to the Centers for Disease Control and Prevention.

So far, according to the CDC, there is one vaccine candidate in Phase 3 clinical trials in the US that requires only one injection. That company – Johnson & Johnson – has not yet applied for an emergency permit from the FDA in the US.

Should I Get the Coronavirus Vaccine Every Year?

At the moment it is uncertain how long immunity of the coronavirus will last.

In some patients with COVID-19, antibodies have been found to be undetectable after several months. New evidence suggests the antibodies only last a few months. Another new dataset suggests that immunity can last for years, the New York Times reported. We continue to rely on new scientific evidence and advice from national and global policymakers.

Vaccine developers are working to increase the effectiveness of vaccines to provide longer immunity than an actual coronavirus infection, according to Johns Hopkins University.

Keep in mind that even if you get the vaccine, health experts say it is still necessary to practice social aloofness and wearing a mask as they learn more about “the protection that COVID-19 vaccines provide under real conditions, ”said the CDC.

Am I better protected against the coronavirus if I am vaccinated twice?

Trying to get more than one COVID-19 vaccine is not recommended for several reasons. Due to the limited supply, it is better for everyone to get a single vaccination (which requires two separate injections about a month apart) to ensure that the entire population has the opportunity to be immunized .

According to the CDC, receiving a vaccine twice in the past has not shown increased immunity to the same pathogen. For example, two shots of the flu vaccine will not increase immunity.
