A medical moment, Coronavirus conversation, new topics

Is there underlying coronavirus immunity in East Asia? For instance why did Peru do so much worse than Vietnam? All throughout East Asia there is very little in the way of coronavirus fatality versus other parts of the world. Has there been background coronavirus to which the population has gradually become immune?

Herd immunity has been downplayed, but it seems to be the real difference between different countries' different outcomes. Sweden and Italy are exiting the so-called quote second wave" of coronavirus while France and Germany, UK still struggle. Likely this is because Sweden and Italy had more penetration of coronavirus early on in the spring.

Also, what should I take the vaccine" people ask. Well the answer (as with many other questions) is, "IT DEPENDS!". Try to stratify and differentiate your own personal risk based on age and health factors. It is a 1000 fold difference between the younger age groups and the elderly in terms of coronavirus case fatality risk and likelihood.
