As more and more people become fully vaccinated, many are wondering when life will return to normal. But before you ceremoniously throw away your face masks, experts warn that we’ll need to continue wearing them a while longer.

“Face masks and physical distancing will need to continue into the foreseeable future,” explains infectious disease specialist Kristin Englund, MD. “Unfortunately, getting vaccinated does not instantly mean we can go back to how life was before. Until we have some level of herd immunity, the vaccine is now just another layer of protection against COVID-19.”
In order for us to reach herd immunity, 50% to 80% of the population will need to be vaccinated. And since it will take time to ramp up production and distribution of the vaccines, Dr. Englund urges folks to manage their expectations about a quick return to normal.
“The vaccines are certainly a step in the right direction – and a reason to celebrate – but we’re not out of the woods yet,” she says.
5 reasons to still wear a face mask after you’ve been vaccinated
Here, Dr. Englund explains why it’s important for those who have already been vaccinated to continue wearing a mask:
- It takes time for the vaccine to kick in. You won’t reach the 94% or 95% effectiveness rate until a couple of weeks after your second dose of the vaccine. After the first dose, you do get a partial immune response, which is good news, but it doesn’t mean you’re immediately protected the minute the needle goes in your arm.
- The vaccines do not provide 100% protection. Although the vaccines are incredibly effective (and were nothing short of amazing in terms of turnaround), they only offer 94% to 95% protection. There’s no way to tell who the 5% will be who don’t respond to the vaccine and will still be at risk for COVID-19. In comparison, the measles vaccine is 97% effective after two doses. The vaccination program began in the U.S. in 1963, but the disease wasn’t considered eliminated until 2000!
- Those who have been vaccinated might be asymptomatic spreaders. The vaccines prevent illness, but more research is needed to determine if the vaccines also prevent transmission. Experts are concerned that vaccinated people can still become infected without symptoms and then spread it to others who have not been vaccinated yet. Since the pandemic unfolded nearly 10 months ago, experts have worried about silent spreaders, aka those who are infected but don’t show symptoms. If vaccinated people don’t continue to wear a face mask until more people receive their second dose, they could cause the virus to keep circulating. Getting vaccinated means you’re much less likely to get sick and develop symptoms yourself, so it’s critical that we protect others while they wait for their turn to receive the vaccine.
- We still need to protect those with compromised immune systems and those who can’t be vaccinated. We know that people with chronic medical conditions (like heart disease and cancer) are at risk for developing a severe case of COVID-19. And since this population wasn’t involved in clinical trials, we can’t assume that they’ll have the same 94% to 95% effectiveness. It’s also recommended that if you’ve had an allergic reaction to any of the ingredients in the vaccine, you shouldn’t get it. If you had an allergic reaction to the first dose, the CDC doesn’t recommend getting the second dose either. Some pregnant women (who are also considered high risk and weren’t included in clinical trials) are opting out of getting vaccinated or choosing to be vaccinated after they give birth.
- There are limited doses of the vaccine. There are more than 330 million people in the U.S. Experts estimate that the number of vaccinations needed to make an impact on herd immunity won’t be reached until the fall or winter of 2022.
The vaccine is not an automatic off switch for the pandemic
As much as we’d all like to hope that the vaccine means an instant return to normal – it’s not.
Instead, it’s now one tool in our kit of resources to fight the pandemic. We’ll need to continue universal masking, hand washing, avoiding large crowds and practicing social and physical distancing for a while longer.
“We may see mask guidelines start to change after enough people have been vaccinated and cases and deaths have dropped,” says Dr. Englund. “But until then, we must remain vigilant in our fight to control COVID-19.”
