I also disagree. at the beginning it was all about reducing transmission and the 95% efficacy with Pfizer was trumpeted incessantly.
Then they realised that that efficacy didn't last long and by the end of 5 months that efficacy was <50%. Then after the second jab the efficacy dropped after 3-4 months and that was when the line became common that you needed the shots plus boosters to reduce your risk of severe disease.
But here is a report of a Canadian study of efficacy against infection a week after a 4th dose.
And yet we have Health Ministers and various "experts" telling us to have the second booster to help prevent our hospitals being overrun. This when infections only reduced 19% and severe disease by 40%.
In pre covid days the Benchmark for vaccine efficacy was > 50% to be accepted for general use. We badly need new vaccines and preferably producing antibodies to other parts of the virus than the spike protein.

Published on July 6, 2022, this Canada-based study found the marginal effectiveness of a fourth dose (95% of vaccine recipients received Pfizer mRNA-1273 (Comirnaty) vaccine as the fourth dose) seven days or more after vaccination versus a third dose received 84 or more days previously was 19% (95% confidence interval 12% to 26%) against infection, 31% against symptomatic infection, and 40% against severe outcomes.
