Since I've tried to elicit a response for days to no avail, I am going to provide my own explanation for why this simple question is not being answered.
The crux of the vaxx-zealot argument is that there can be no legitimate reason anyone would question the benefit of the vaccine for everyone. Any such questioning is to be tarred as "anti-vaxx" so that the concerns can simply be dismissed rather than discussed.
I'd like to take moment to point out that I have said on this forum on numerous occasions that I am not "anti-vaxx". I have received all of my regular childhood vaccinations and so have my children. My argument is and always has been against the overly broad recommendation for everyone to receive COVID vaccines in perpetuity despite having no evidence that there is a benefit to do so. There are also very real concerns with potential harms, and the less benefit one derives from a medical intervention, the more adverse events become concerning.
If the vaxx-zealot position were to acknowledge, like almost all of the rest of the world, the COVID vaccines are best suited to the elderly and those with serious co-moribidities, this calls into question why the US is now an outlier in recommending them to all age groups, especially when there are studies that show an adverse event rate as high as 2,000 per million doses administered.
But before any of this can be discussed in earnest, one has to acknowledge that there are legitimate concerns with these overly-broad recommendations. One has to drop the "anti-vaxx" nonsense and admit that there are always harms and benefits to any medical intervention, and just because someone has concerns about the harms associate with COVID vaccines does not make them an "anti-vaxxer".
This also calls into question the CDC's recommendations concerning COVID vaccines. Clearly, >80% of the US population is disregarding the CDC's recommendation on COVID vaccines. Why? If the CDC is the reputable health agency that some believe it to be, then why is the vast majority of the US population ignoring their recommendation on COVID vaccines?
But again, any conversation in earnest on this topic requires the dropping of the "anti-vaxx" pejorative. It's nothing more than an intellectually dishonest and lazy way to dismiss valid questions and concerns.
