I think you misunderstood, the GP is commenting on the Pfizer CEO saying that boosters will be required in 6 months which this paper seems to indicate won't be necessary.
Might boosters still be required to provide immunity from new escape variants?
No. The variants are variants, not strains. It's based on gene deletes primarily. More Sneaky just means a bit less effective. Studies suggest about half as effective. So from 90% to 80% etc still highly effective.
Most people would pay $20 for improved effectiveness against newer variants, I would presume.
Most people in 1st world countries (where $20 is not that much) would, but I like that it might not be needed. It's less hassle, and it also breaks all the assumptions were made by the anti vaccine misinformation.
Anti-vax, anti-mask crowd have been so wrong so many times over the last year. I doubt another huge L would change their minds. It's twilight zone level stuff.
Alright. I mean on an individual level, I and I'm sure a large majority of people would take a single booster for improved safety from the variants that took this evolutionary path. All for like $20 (cost of a shot).
