, where fourth doses of the Pfizer–BioNTech vaccine were widely administered, found that they resulted in additional antibodies but provided little protection against infection and waned quickly. Cases of severe illness were down, but scientists on both sides of the issue say there were methodological problems with the study and the results were reportedwhether that group received better long-term protection against serious disease than people who received just a third dose.
Vaccines are much better at providing lasting protection against serious disease. That’s not a weaker version of protection from infection; it’s a different process that employsthat work more slowly than antibodies already in the bloodstream. Offit says these cells might last years; it’s not known exactly how long.
From Offit’s perspective, as long as the vaccines protect against severe disease, no more is needed except for those whose immune systems cannot mount a strong defense. Otherwise, we’re looking at vaccinating huge portions of the population every few months for minor illness. We don’t do that for any other disease.
