This doesn't look like 3 jabs is good unless i have read this wrong, i am no statistical expert but for 50 59 onwards third dose patients are higher than unvaccinated, can someone explain?
Perhaps it has something to do with the age groups that were given the 3 dose earlier. Anyway there still will be an age relationship. Plus of course there are way way more vaccinated people in that age group. The percentages are usually in the same report.
Some respects irrelevant anyway. The important aspect is levels of infection in the population against hospital entries - has it changed since people have been vaccinated. Some on here might argue that it was down to the fact that the phase of the moon was getting nearer and nearer to full. Most are more sensible.
Effectiveness can be measured in 2 ways. One is protection against symptomatic infections and the other is prevention of death when infections are symptomatic,. The other way is to look at the amount of use of the 3 phases of covid treatment. Oxygen and drugs, ventilation and invasive ventilation.
