No, I'm comparing the much higher efficacy of the polio vaccine and low prevalence of the polio disease to the significantly lower efficacy of the Covid vaccines and the high prevalence of Covid at present. That means the fact that the polio vaccine is non-sterilizing isn't very important, while the fact that the Covid vaccines are non-sterilizing is a big deal and undermines some of the public health policy decisions.
actually, the polio vaccine doesn't have much higher efficacy, and the covid vaccines don't have much lower efficacy, they have similar efficacy in reducing severe symptoms
That's not what the referenced links says. It says the polio vaccine has 99 to 100% efficacy. The published numbers for Covid vaccines show the virus vector and mRNA vaccines are around 95% efficacy. That's a large difference.
that is actually a very small difference
maybe your source says that 99 is "much higher" than 95, and I just missed it?
No. The difference between 95% and 99-100 % is a very large difference.
