The WHO has repeatedly warned that unequal distribution of vaccines worldwide has led to low immunization rates in developing countries, leaving vast populations vulnerable to the emergence of new variants. The WHO had set a target for every country to vaccinate 40% of its population by the end of 2021. However, 92 countries have not achieved that goal, according to the WHO.
This despite arguing last month that booster shots were not a workable strategy.
Director-General Tedros is straddling so many fences it's a miracle he's not beset by splinters.
Strictly speaking, to be a control group the Vax rate would have to be zero. That's not a possibility.
However, correlation can be analyzed based on Vax rates, low vs high. Correlation is not causation but it is connection, and thus comparisons across the spectrum of Vax rates are valid and potentially informative.
Countries with really low vax rates would act as control groups, and THEY really don't want that.
Gosh, I wonder why?
