This article is so garbled I can't even tell what the study purports to find, but I managed to find the original report here. It looks like it's saying that levels of antibodies in the blood go down with time, which is expected and may not say anything in terms of duration of immunity (antibodies != entire immune response). There is one graph that shows neutralization against "pseudovirus" goes down with time, but I think that's also to be expected against blood in a test tube. It's hard to know exactly what this means in terms of the duration of protection, and it says nothing about what it does to the severity of the illness if you did contract the disease. But I think we should probably expect to be getting covid-19 boosters either yearly or every other year now. Maybe they'll just bundle it with the flu shot. My dream is that mRNA makes it easy enough to create vaccines against a huge array of viruses that we start getting covid/flu/rhinovirus shots and murder all these stupid viruses once and for all, but that may not be in the cards.Emory’s Vaccine Center found that Moderna's COVID-19 vaccine immunity dulled after six months, but not to such an extent that the vaccine was ineffective.www.boston25news.com
