Interesting to see that countries with low vaccination rates are having these problems.
One might believe there is a relationship.
You seem to be confused with your science lecture. What has IFR to do with required vaccination rate
Its called science. Or rather mathematics.
If you have a very infectious disease like measles (high R0) you need a high percentage of the population vaccinated to stop community spread. Over 90% for measles, mumps etc.
If you have a mildly infectious disease like influenza (low R0) then you need a much lower percentage to have exactly the same public health effect < 50%.
With a very infectious disease like measles if you are lower than 90% vaccination rate outbreaks will be common. With a mildly infections disease like influenza and SARs CoV 2 a vaccination rate of <50% and 90% have exactly the same results from a public health disease control standpoint. Because of the mathematics of infection spread.
That assumes the vaccines works. Which the SARs CoV 2 vaccine dont. The high risk population have high repose to vaccination. Which they dont with SARs CoV 2. And that the disease has a epidemiological profile that makes it amenable to complete suppression. Which SARs CoV 2 most certainly does not. Just like the common cold in fact.
So in public health terms all current SARs CoV 2 vaccines are little more than high risk (by traditional public health vaccines standards) placebos which have little or no effect on either the pathology of the disease or mortality rates.
So are you up to date on your Tdap booster?
