Caution is probably best advised for those not fully vaccinated while cases continue to rise
We haven’t yet heard how the Janssen and Moderna vaccines perform in this respect, but most scientists believe they will hold up well in preventing serious illness.But what about infection with the virus, which can lead in some cases to long-term effects and onward transmissions to others?
Data on the performance of other vaccines in preventing infection is generally lacking so far. And while manufacturers say they will protect well, they have also begun talking about the need for additional booster doses. This adds up to more cases, mostly among younger unvaccinated people but also including breakthrough infections in the vaccinated and especially partially vaccinated.
