> "and reduces the risk new mutations" likely the opposite is true. It is called evolutionary pressure.
Chicken and egg problem: You can't have evolutionary pressure without an environment to operate in. Vaccines reduce the space in which they can attempt to successfully mutate.
That environment of evolutionary pressure is exactly what is being created. An environment where strains with higher fitness for immune escape are more able to spread, in a compounding manner. Particularly with leaky vaccines as we're using for c19 that do not prevent contraction with high efficacy.
or read how antibiotic resistance comes about, which seems to be less contentious / politicly affected... But the same evolutionary mechanism is at work.
