[FRIAM] References for Nick which may interest others

[Barry MacKichan]

On Zoom last Friday Nick asked for more information about an assertion I 
made that measles erases
immunity memory. This is from an email my daughter sent to me and my 
college roommates (and spouses and offspring). If you need a reference 
to the literature, I can probably get one from my daughter, but with 
what I’m copying here, you would probably find find some with Google.

After that is a link to an academic lecture on why a Covid-19 vaccine is 
“easy” when compared to other vaccines. What’s not so easy is 
compressing 5 to 20 years of effort into one year. That part of the 
discussion starts about at 9:20.


*Measles story. I share this with my class to give my students a 
counterargument to anti-vaccine people who believe a "natural" infection 
is better than vaccination, because, it's natural. The measles vaccine 
was integrated into the childhood vaccine schedule at different times 
around the world (1960's - 1980's). In every country, after the vaccine 
was introduced child deaths from *all causes* fell drastically. No one 
knew why - suggestions were that it corresponded with better medical 
care, etc. In 2015, it was shown that one of the cells that measles 
infects (and kills) are memory B cells - the cells that make antibodies 
to all of the pathogens you've seen before. They are wiped out in 
measles. After a child has had measles, they become susceptible again to 
every disease that they've already been exposed to - the immune system 
is essentially reset. It was known that you get major immune suppression 
for a few weeks during a measles infection, but this study showed that 
immune memory doesn't bounce back once you recover. This is why measles 
vaccination protects children from dying of not just measles, but many 
common infectious diseases. Not all pathogens kill immune cells like 
that, but most throw a wrench in the works one way or another.*
