I'm not anti-vax, but this guy is basically telling everyone that the vaccines are not as effective on the variants, but let's try to play whack-a-mole with them anyways. A strategy that's already been shown to fail. It's the equivalent of McNamara telling us we can still win in Vietnam when he dam well knows the strategy isn't working.
I'm not expert enough to decide that, but I have yet to see a strategy that convinces me it could be effective.
