. – Covid-19 infections are on the rise once more in the USA. Whereas greater than 99% of deaths happen among the many unvaccinated, anecdotal stories of totally vaccinated individuals nonetheless testing constructive for COVID-19, together with a number of New York Yankees baseball gamers, abound.
How involved ought to vaccinated individuals be of contracting COVID-19? In case you are vaccinated, can you continue to move the coronavirus to different individuals, similar to kids who are too younger to obtain the vaccine? Probably the most transmissible delta variant modifications the equation and what precautions ought to vaccinated individuals take?
For some steering throughout these unsure instances, we turned to CNN Medical Analyst Dr. Leana Wen. Wen is an ER Doctor and Visiting Professor of Well being Coverage and Administration on the Milken Institute College of Public Well being, George Washington College. She can be the writer of a brand new guide to be printed subsequent week, “Lifelines: A Physician’s Journey within the Combat for Public Well being.”
CNN: Can vaccinated individuals get covid-19?
Dr. Leana Wen: In case you can. Right here’s what covid-19 vaccines do: At the start, they defend you very nicely towards severe illnesses. That’s the key. This can be a illness that has claimed the lives of greater than 600,000 Individuals and tens of millions of individuals all over the world. In case you obtain the vaccine, you recognize that it is vitally unlikely that you’ll change into critically sick to the purpose of needing to be hospitalized or succumb to the illness. Based on federal well being officers, 99.5% of COVID-19 deaths are now among the many unvaccinated. That may be a true testomony to the facility of vaccines.
Vaccines additionally defend towards covid-19 illness, however this safety is just not 100%. With the delta variant, vaccines could also be even much less efficient towards gentle illness, though they are nonetheless efficient towards extreme illness.
Meaning progressive infections, or infections in individuals who are totally vaccinated, can and do happen.
CNN: Does it matter for those who’re in a extremely contaminated group? Is somebody who has already been vaccinated extra more likely to get an an infection?
Wen: Sure, and that’s the reason what occurs round you is necessary, even for those who are totally vaccinated. The danger is additive. The vaccine protects you nicely, however for those who are always uncovered to individuals who carry the coronavirus, sooner or later you might have a brand new an infection.
I’ve used the analogy of a raincoat earlier than. The vaccine is a wonderful raincoat. If it’s within the occasional drizzle, it’ll most likely be tremendous. However for those who go from one thunderstorm to a different, sooner or later, you might get moist.

That is additionally the explanation why we’ve got to see vaccination not solely as a person selection. Even for those who are vaccinated your self, it is crucial that the individuals round you are vaccinated as nicely.
CNN: Do we all know how frequent post-vaccination infections are, or if individuals who are vaccinated however change into contaminated can move them on to others?
Wen: These are actually necessary questions, and sadly, we don’t know the solutions. In Could, the U.S. Facilities for Illness Management and Prevention (CDC) determined to cease monitoring gentle infections. They solely report circumstances of post-vaccination infections severe sufficient to trigger hospitalization and dying. Many people in public well being have argued that we additionally must know the info on gentle infections. You will need to understand how usually they happen and between whom. For instance, are they extra frequent in older individuals and people with compromised immune techniques, suggesting that these individuals may have a booster shot sooner? Do they enhance in frequency after a sure level after vaccination and are they extra frequent with one vaccine than one other? Do individuals with post-vaccination infections develop long-term covid?
One other key query is whether or not individuals with post-vaccination infections can transmit COVID-19 and infect different individuals. Earlier research discovered that vaccination additionally considerably diminished the quantity of virus somebody uncovered to COVID-19 would carry. That even when they check constructive or develop gentle signs, they are unlikely to contaminate others. Nevertheless, these research had been carried out earlier than the delta variant grew to become the dominant type of the virus within the US The CDC has reported that 83% of US circumstances are now because of the delta variant.
Different analysis finds that the unvaccinated who are contaminated with the delta variant carry 1,000 instances the quantity of virus as individuals with the unique variant. That calls into query what occurs if somebody is vaccinated, however contaminated with the delta variant. We merely have no idea, at this level, how doubtless it’s that an individual vaccinated with an an infection because of the delta variant is contagious to others.
Those that don’t get vaccinated will likely be contaminated, in response to infectologist 4:03
CNN: Do the unknowns surrounding the delta variant change your suggestions for vaccinated individuals who work together with others?
Wen: I might be very cautious till we’ve got extra knowledge. A vaccinated individual round different totally vaccinated individuals might be fairly protected and wouldn’t want precautions like masking and distancing. However, a vaccinated one who is continually uncovered to unvaccinated individuals, in crowded, closed environments the place nobody wears masks, may change into contaminated. And even when they don’t have signs, there may be positively an opportunity that they are carrying the virus and infecting others.
Till we all know extra about whether or not vaccinated individuals who contract the delta variant can move it on to others, I urge individuals to be cautious in the event that they dwell at dwelling with unvaccinated or immunosuppressed relations. They need to take into account sporting masks indoors like grocery shops and attempt to keep away from high-risk environments like crowded bars the place different individuals round them are unmasked and have unknown vaccination standing.

CNN: To be clear, would you continue to suggest vaccines?
Wen: After all. A very powerful factor that covid-19 vaccines do is defend towards hospitalization and dying. They’ve confirmed remarkably efficient at this, even with the delta variant. New infections are to be anticipated, and the extra infections that happen among the many unvaccinated, the extra infections there will likely be amongst these vaccinated.
The important thing to stopping the pandemic is for us to attain a excessive sufficient stage of immunity that the virus has nowhere to go. We are able to get there, however all of us should do our half and get vaccinated. The vaccine protects the person and likewise protects these round us.
