"Data indicates that the jab wasn't worthless. It's a factor in those countries with lower Covid death rates."
Actually the countries with the lowest Covid death rates are mostly in Africa where very few people are vaccinated. The countries with the highest death rates generally have high rates of vaccination.
We can speculate on why Africa had so few Covid deaths, but recent data makes it pretty clear that the countries with the most excess deaths (i.e. - a higher number of deaths from all causes than would be expected from historical norms) are those where a high percentage of people are vaccinated. The exact mechanism that explains this is not yet well defined but researchers are beginning to look at this and it appears to be strongly correlated with vaccine usage.
