Immunized people spread the virus less generally because they are less likely to get infected in the first place. In early September, the CDC found that for every one vaccinated person, six unvaccinated people were testing positive for COVID. But there are plenty of reasons to be optimistic beyond that. Some recent studies show that even if they are already infected, vaccinated people are less likely to spread the coronavirus than unvaccinated people. Ross Kedl, a professor of immunology at the University of Colorado School of Medicine, told me: “We come back to this genre of Yeah, it could happen, but it seems to be a very rare event. out.
He showed me two studies, both unreviewed, to make his point. One shows that although transmission did occur among vaccinated individuals in Provincetown [Mass.], those cases represent what Kedl calls a “very limited” proportion of the total number of infections that occurred as part of that outbreak. In another study, researchers in the United Kingdom found that the Pfizer and AstraZeneca vaccines consistently reduced transmission of mutations. Much of Delta’s initial concern was based on something called “viral load” – the amount of virus a person carries when infected. But the researchers concluded that viral load is just one of many factors associated with reduced transmission. In other words, even if vaccinated and unvaccinated people have the same viral load, that doesn’t necessarily mean they are equally likely to spread the virus.
