How Long Does the Covid Vaccine Last?


With millions of people across the U.S. getting the Covid vaccine every day, there’s a lot to feel optimistic about heading into the rest of spring and summer. But have you stopped and wondered how long your vaccine will last? You’re definitely not the only one.

A new report from the Centers for Disease Control (CDC) that come out in early April tried to answer this question. Scientists studied over 4,000 vaccinated essential workers who received the Pfizer shot, and they found that the vaccine keeps its effectiveness for at least six months. A separate study that came out days later showed similar longevity from the Moderna vaccine. Johnson & Johnson may show similar signs of keeping their efficacy over time, but it hasn’t been on the market for as long.

We’ll know more as time goes on and we’re able to study subjects who got a Covid vaccine long ago, but some doctors believe that these vaccines should last at least a year without requiring additional boosters. That said, only time will tell, especially as new strains of the virus continue to regularly pop up and may require new protection.

Though these vaccines’ overall durability may not be entirely in your control, there are a few simple lifestyle changes you can keep in mind to make sure you get the maximum amount of efficacy from all three shots. Health experts are recommending that people stay away from alcohol during the time they’re getting their vaccine shot(s) and the two weeks immediately following a final vaccination. They also say to focus on sleeping well and generally eating healthy before, during, and after your inoculation period so that your body gets the optimal benefits.

It may seem like we’re still dealing with so many unknowns, but remember that it’s all worth it to be able to see your friends and family in the coming months with a little more peace of mind!
