Well yes it is a calculation on the 50+: by distributing it over each age bracket, you should have something catastrophic on the very old and excellent on the youngest. Then by taking each result by age group in proportion to the population share by bracket, this will mathematically increase the average efficiency and you will no longer have 65% or 53% but 80%. This is how the labs find 9x% and your car makes 3l until you fill up the first tank.
This is also why the results per tranche for Italy appeal to me.
Italy must be mainly PIFzer while UK is Astracécaca.
Is Italy affected by the new Delta variant? Otherwise it makes sense that the results are higher.
The problem being the efficacy over time of the vaccine with a virus which mutates every 3 months: see UK and Israel. Finally, problem for those who choose to get stung, for the labs on the other hand it is quite beneficial, especially when the friends govern and that the friends write the press articles if you see what I am hard-boiled.
