This is great news, adding to a report in Nature that the natural immunity produced in people who have already had covid may last a lifetime.[1]<p>In case you hadn't heard, the Cleveland Clinic--consistently regarded as one of the top hospital systems in the United States and in the world--recently shared a study of 52,238 patients showing zero incremental benefit from the jab to the previously infected, recommending that "people who’ve had COVID-19 don’t need to get vaccinated."[2]<p>[1]<a href="https://www.nature.com/articles/d41586-021-01442-9" rel="nofollow">https://www.nature.com/articles/d41586-021-01442-9</a><p>[2]<a href="https://www.healthline.com/health-news/new-study-determines-people-whove-had-covid-19-dont-need-to-get-vaccinated" rel="nofollow">https://www.healthline.com/health-news/new-study-determines-...</a>
Someone should find out if natural antibodies provide long term immunity, including variants, since so many people already contracted Covid-19 and recovered.<p>Especially among young adults teenagers and children since they have yet to be vaccinated at scale.
What doesn't seem to be addressed is why COVID-19 germinal centre response might produce lasting immunity while, say, flu vaccination (which also produces germinal centre responses) doesn't
Has there been any work done on the severity of the COVID 19 variants? My understanding is variants of highly dangerous viruses rarely keep the high level of risk as the progenitors.<p>Does the delta variant and others pose the same risks? Are we over responding to a virus family group?
So there's no chance of immune escape? I thought at the very least, it'd be like the flu vaccines where the virus mutates often enough that we all need periodic booster shots.
The headline is wrong. The article is about mRNA vaccines in general.<p>Moreover, Pfizer is partner of BioNTech, which developed the vaccine. I don’t understand why OP omits that and solely credits Pfizer.
What is the word on how much of an impact long term immunity had on how well some regions managed the virus?<p>Edit: I should say I'm expecting to see that it was not impactful. Would still be nice to see papers on it.
The mRNA vaccines have been the silver lining to the whole COVID-19 disaster.<p>They seem “unreasonably effective” against COVID, basically if you had a genie that you could ask to make a vaccine, it would be hard to do much better, other than the requirement for 2 jabs.<p>In addition, the mRNA technology has broad applicability to other issues such as other viruses (such as flu) and even cancer!
