> What if a new more deadly, more infectious or vaccine-resistant variant appears that could have been prevented from a quick mass vaccination?

The vaccine rollout could only ever proceed so quickly and we already have a 'vaccine-resistant' variants. So I agree the benefits look incredibly dubious.

Remember the so called vaccines don't even claim to stop people spreading or catching the virus. They only reduce rates of hospitalization. Vaccine is a misnomer. They should just be called therapeutics. They're doing almost nothing to stop the spread.
