When should vaccinated people wear masks now? An expert weighs in

To distinct up confusion about masking, we turned to CNN Medical Analyst Dr. Leana Wen for her thoughts. Wen is an emergency doctor and visiting professor of health and fitness plan and management at the George Washington University Milken Institute University of General public Overall health. She’s also author of a new guide out later this month, “Lifelines: A Doctor’s Journey in the Combat for Public Health.”

CNN: Are there conditions in which vaccinated people today should return to sporting masks indoors?

Dr. Leana Wen: Of course. Masks are nevertheless necessary in some options, this kind of as airports, on planes and trains, and in hospitals. If a business enterprise calls for masks, you should still put on a mask, so it can be a good apply to carry a mask all-around with you in circumstance you need it.

The much more difficult query gets to be, what about configurations in which you you should not have to use a mask — when may you pick out to dress in one? Here are the factors I’d take into account.

To start with is your well being and the vaccination status of these in your household. If you are immunocompromised, you should really be carrying a mask in all indoor configurations in which you could be uncovered to unvaccinated individuals.

If you reside with somebody who is immunocompromised or with younger, unvaccinated children, you could however want to take supplemental safety measures. Your prospect of contracting Covid-19 and passing it on to your household is much lessen when you are vaccinated, but it is not zero. Look at wearing a mask in high-possibility options, this kind of as crowded grocery outlets or indoor church products and services.

2nd is the stage of coronavirus an infection and the amount of vaccination in your group. These two are frequently correlated: The regions with higher charges of vaccination also are likely to have reduced concentrations of an infection.

If you might be residing in an location where by in excess of 80{e32b4d46864ef13e127a510bfc14dae50e31bafd31770eb32fd579b90b39f021} of grownups are vaccinated, and the Covid-19 rates are really small, your likelihood of encountering an unvaccinated, contaminated man or woman is considerably minimized. You are possibly safer heading devoid of a mask there when compared to, say, if you are dwelling in an region with a lot less than 30{e32b4d46864ef13e127a510bfc14dae50e31bafd31770eb32fd579b90b39f021} of grown ups vaccinated and where by the Delta variant is surging.

CNN: Some individuals looking through this will inquire, “Why are we even talking about masks again, when the vaccines are intended to work so properly?”

Wen: The Covid-19 vaccines we have in the US do perform very very well. But no vaccine functions 100{e32b4d46864ef13e127a510bfc14dae50e31bafd31770eb32fd579b90b39f021} of the time. Consider of the vaccine as a incredibly efficient raincoat. If it truly is drizzling, you are going to be shielded. If the rain is coming down hard, you may nevertheless be wonderful. But if you are likely in and out of rainstorms all the time, you could end up having soaked.

Threat is cumulative. If you have various encounters each day with unvaccinated people today, and there is a superior degree of local community transmission in your region, your prospects of having a breakthrough an infection after vaccination will raise. You can lessen that danger by putting on a mask in the maximum threat settings.

CNN: What if you happen to be heading to do the job and everybody in your office is vaccinated? Do you however need to have to don a mask if you can find no distancing?

Wen: Good issue. We know that vaccination considerably cuts down your probability of becoming infected and of currently being an asymptomatic carrier who could transmit the virus to some others. Your likelihood of turning out to be contaminated from a vaccinated particular person, if you might be also vaccinated, is virtually zero. Going to an office in which anyone around you is recognized to be vaccinated, even with out masks and distancing, is very protected.

CNN: What about the reverse — what if you have to be back at perform, but vaccinations aren’t expected? Really should you mask up?

Wen: That relies upon on the other elements we talked over. Take into consideration your wellbeing, then the chance that another person at perform could be infected primarily based on neighborhood transmission and vaccination prices in your spot. Also take into account the instances at operate. Are the men and women you are in near speak to with vaccinated? Let us say that your place of work won’t have a vaccination plan, but the two individuals who share your office environment or the 3 persons with cubicles closest to you are completely vaccinated. That would be a rather secure atmosphere, and you possibly you should not have to have to be carrying a mask at your desk.

On the other hand, if you are asked to go into cramped, poorly ventilated convention rooms with persons who you doubt are vaccinated, take into account wearing a mask there, or, better however, see if you could go to the assembly nearly.

CNN: Does the form of mask make any difference?

Wen: If you are immunocompromised and are in a substantial-threat placing, you ought to be wearing an N95 or KN95 mask or double-masking. In any other case, a well-fitting 3-ply surgical mask should really be enough, while if you might be snug with the N95 or KN95, there is no damage to donning that in crowded indoor options.

CNN: Are there any outdoor options the place you would recommend a vaccinated man or woman dress in a mask?

Wen: Not at the instant. The ventilation that arrives with becoming outdoor lowers transmission so much, as does vaccination. A human being who is severely immunocompromised could nevertheless desire to dress in a mask at crowded ball online games or live shows, but if not, outside masking should really not be desired for vaccinated people today.

CNN: What if people today believe that you might be unvaccinated mainly because you might be putting on a mask?

Wen: A whole lot of people who are vaccinated and want to be extra cautious are wearing masks. It could even be that the people carrying a mask in general public spots are truly vaccinated, and it truly is the people who are unvaccinated who are walking all-around unmasked. You should really focus on carrying out what helps make you at ease. If you would come to feel a lot more comfortable donning a mask in some options, you must do that.

What happens to you when you play with your kids

CNN: How does the Delta variant influence your recommendation?

Wen: Now that more than half of new bacterial infections in the US are caused by this variant, you should suppose that if you were to arrive into call with an individual with Covid-19, it’s the Delta variant you happen to be encountering. This variant is additional transmissible than any of the past variants. There is some proof that those people contaminated with the Delta variant also have extra virus, hence producing them far more likely to infect other people. The vaccines we have do look to be powerful in opposition to the Delta variant, nevertheless significantly less efficient than they are in opposition to other strains.

CNN: To be clear, unvaccinated persons however will need to put on masks?

Wen: Suitable. The steering for unvaccinated men and women has not modified. If unvaccinated persons are all around other people who are unvaccinated — or men and women who are of unknown vaccination standing — they need to be donning masks indoors. Outdoor, the possibility of transmission is small, so no masks are essential there. This applies to children as well, so young children underneath the age of 12 who are not suitable to be vaccinated ought to however be putting on masks indoors when all over other unvaccinated little ones.

With the Delta variant on the increase, I would be even far more vigilant than prior to. If there is a situation the place you might be on the fence about no matter if to place on your mask, I would err on the facet of warning and just do it.
