I do believe the vaccine is worthwhile in the at risk populations. Elderly, multiple medical issues, etc. But even the initial data in the trials is pretty eye opening. When Pfizer said the vaccine was “95%” effective last year, that was based on a trial of around 43,000 people. Half got vaccine, half placebo. 162/21,500 people in the placebo group got Covid. 7/21,500 in vaccine group got Covid. So, 7/169 total cases is where the 95% comes from. But in reality, 99.6% of their total subjects never even got Covid, including 99.3% of the placebo group. So, out of the total, if you had placebo there was a 99.63% chance of not getting Covid and in the vaccine group a 99.98% chance of not getting it.
In fairness, those numbers were likely also skewed due to non-pharmaceutical interventions (social distancing/lockdowns/decreased capacities,etc). So in “real world” situations, the vaccines would likely show a more dramatic effect.
Again, the biggest screw up was marketing these as disease preventing vaccines. If they had been from the start shown as what they are….interventions to reduce severity of illness and death, then I think we’d be in a much better place.
