If You've Done This Recently, Your COVID Risk Is Lower, Study Finds
This past behavior might have lowered your risk of getting COVID by 60 to 80 percent.
There are a lot of new precautions you need to take to actively lower your risk of contracting COVID. Before the coronavirus pandemic hit, you likely didn't have a mask on-hand at all times, and you definitely didn't worry about keeping six feet of distance between yourself and others. However, a new study shows that there's one coronavirus precaution that you may have been taking for years without realizing it. Keep reading to find out if you've already taken this step to protect yourself, and for more ways to stay healthy, Inhaling This Could Reduce Your Severe COVID Risk 90 Percent, Study Finds.
If you've gotten vaccines in the past few years, you could be less likely to get COVID.
A July 2020 study from the Mayo Clinic—which has not yet been peer-reviewed—examined over 137,000 medical records and found a correlation that suggests vaccines can help protect you from COVID, and not just the shots targeted at the virus. During a Feb. 17 interview with CBS, study co-author Andrew Badley, MD, said the research concluded that people who have received various vaccines in recent years could be at a lower risk of contracting coronavirus. "If you've received a number of different vaccines previously, your risk of having a positive SARS-COV-2 diagnosis was less," Badley said.

The vaccines that could be protecting you are common shots.
Of course, the Pfizer and Moderna COVID vaccines will help lower your risk of getting coronavirus, but the study found that routine vaccines could also play a part in keeping you virus-free. The study concluded that when the polio, measles-mumps-rubella, geriatric flu, hepatitis A and B vaccines, among others, were administered in the past one to five years, the person had a lower chance of contracting COVID.
If you're an adult, you may not have received many of these shots since your school days, but if you've gotten them recently, they could contribute to your COVID protection. And for more up-to-date information, sign up for our daily newsletter.
This protection is a result of vaccines training your immune system.
"Normally, we think of vaccines as teaching the immune system to react and protect against very specific invaders—measles, polio, mumps, pneumonia, flu, and so on. Turns out the immune system can learn from vaccines in unanticipated ways," explained CBS correspondent Max Gomez, MD. All the vaccines you've received throughout your life have prepared your body to fight off invaders.
"Think of your immune system as a muscle. The more often you exercise that muscle, the stronger it is," Badley said. "Immune training is the reprogramming of innate immune cells so that when they encounter a subsequent challenge, they have a more robust response."

These vaccines are not a substitute for the COVID vaccine.
If you're missing any of these essential vaccines, it may be time to schedule an appointment to catch up. "While the protection from the non-COVID vaccines isn't total, it is a reason to make sure that you and your children are fully vaccinated," Gomez said. But although these routine vaccinations might help you stay safe from coronavirus, but they're not a replacement for the COVID vaccine. In addition to these shots, you should get the COVID vaccine once you're eligible. And for more on the future of vaccination, This Is Who Should Wait for the Johnson & Johnson Vaccine, Experts Say.
