With so many Americans vaccinated and millions of Americans vaccinated every day, it’s natural to wonder how long this protection will last in anticipation.

The answer is as simple as it’s unsatisfactory: no one knows.

“I still don’t know how long the immunity from the vaccine I have now will last.” Dr. Catherine O’BrienLeads the Vaccine Division of the World Health Organization, Said in the podcast.. “You really have to wait for time to see how long these vaccines last.”

The first two vaccines Approved by the Food and Drug AdministrationNone Made by Pfizer and BioNTech, Other Made by moderna — Started arming in late July as part of a Phase 3 clinical trial. The second dose was given 3 weeks after the Pfizer-BioNTech trial and 4 weeks after the Moderna.

After the second dose, it will take another two weeks for the immune system to be fully protected. This means that the first people who were fully vaccinated hit the mark in September, about six months ago.

Vaccine makers track these clinical trial volunteers and test them to see if the benefits of their shots are stable or beginning to diminish. So far, both look strong.

In addition, a blood test of 33 people who participated in the first phase of Moderna’s clinical trial showed that coronavirus antibodies were still prevalent six months after receiving the second injection. Those results This month, it was published in the New England Journal of Medicine.

You’ll see how long this performance will last over time.

Meanwhile, both companies Working on booster shots It will stimulate the flagging immune system.Some of those boosters are designed to be more properly targeted New coronavirus mutant It emerged after the original vaccine was created.
