Immunity waning in Israel
Sorry that is not a live link. It is "Big US implications from Israel" by Dr. John Campbell on YouTube.
In a nutshell, he talks about how in Israel many or most of the population are fully vaccinated. Now, however, it appears immunity is waning as the vaccine appears to be only 33% effective against preventing infection. However, it is still very highly effective against severe illness and hospitalization. In the U.K., individuals fully vaccinated around the same time as those in Israel have a much higher effectiveness against infection. I believe around 88% (don't quote me, but something like that). WHY? Reportedly the same vaccine. Dr. Campbell postulates this: In Israel, doses were given 3 weeks apart. In the U.K., more like 11-12 weeks apart.
This has huge implications for the U.S. as our doses were 3 (Pfizer) or 4 (Moderna) weeks apart. Our immunity may be waning already for those of us vaccinated early this year.
Thank you Beth; it is very important to stay informed from credible sources; greatly appreciate.
data is still evolving On Thursday, Israel's health ministry released preliminary data suggesting that, while the Pfizer-BioNTech
vaccine remains very effective at preventing severe Covid-19, it may be
losing effectiveness against milder cases of the disease.
it is useful to recall that "immunity" is used in two different ways 1)immunity from infection 2) immunity form serious illness or dying. Since infection can be asymptomatic our knowledge of Immunity on #1 depends on how much testing we do. That makes it very complicated. So far very few vaccinated people have ended up in the hospital or dying, but we only have 6 months expereience.
