herd immunity due to mild/subclinical infections

herd immunity plus vaccine immunity in the USA means the epidemic is pretty well over. 

.....

this is good for populations like in the USA, where most people are low risk.

But after a year of no jobs, lock down and malnutrtion due to no money, the herd immunity might not work in the poorer countries.

today's videos are about South America "despite high vaccination numbers"

....

.the problem is the new variants, which are more infectious but most vaccines stop them. (i.e. meaning keeping a distance and masks won't work as well).

the reports of "numbers of cases" ignores that there are fewer deaths because most cases are in low risk younger people in the west, who don't die.

this is not true in poorer countries, where poor nutrition (made worse by unemployment from the economic shutdown) is common, and often these countries were given the Chinese Sinovax as part of China's "vaccine diplomacy". (in above video this is discussed starting at about 14 minutes into the video ).

and Singapore's Straits Times notes that the Sinovax has weaker protection, as shown in an Indonesian study.
