That benefit alone is, to me, worth getting jabbed, and is the primary reason my wife and I did.
I am as yet unconvinced about efficacy with regard to infection and transmission. Viruses mutate, it's what they do, RNA viruses especially.
I've been getting an annual "flu shot" for many years, because every year the flu is different. And every year it's a crapshoot as to how effective it will be against the variants-du-jour. But the annual flu shot isn't marketed as a "booster" on the original flu shot, and therein lies my objection to the current nomenclature.
I think it would be a lot more honest if they just said, "The WuFlu virus is mutating like all viruses do, and we'll be rolling out a new shot as rapidly as we can figure out what it's doing next."
In any case, I don't expect this mess to settle down for a few years, and we may never know the truth about what really happened in 2020. So it goes.
So it goes. We can only make the best decision we can with the information currently available.
