Or it could just be that Coronavirus is a single stranded rna virus, thus subject to frequent mutation and impossible to control 100%.
I have received both Moderna shots and two Moderna boosters. In August I had an extremely, mild, virtually imperceptible, case of Covid which passed quickly.
Flu shots don’t prevent you from getting the flu, but they mitigate the experience. Flu is also a single stranded rna virus, subject to continuous mutation.
Nobody (other than anti-vax cranks) questions the flu vaccine and they should not question the coronavirus vaccine for the exact same reason.
On the other hand, Smallpox was a double stranded dna virus, not subject to mutation, which is why it was successfully eradicated by vaccines.
People really need to go to their local public college or university and audit a microbiology course. An understanding of microbiology would prevent threads like this.
HOWEVER.
<Noting DougBH’s post from moments ago>
I agree with him regarding vaccinating children, but NOT for the reason he gives, but simply because it is no longer necessary at this point.
As I said earlier in my post vaccinations against rna viruses are ALWAYS imperfect, particularly against single strand rna viruses, due to the frequent mutation inherent in rna structures. It is impossible to create a perfect rna vaccine.
I no longer believe that it is necessary to vaccinate children, unless they have a health condition that would make them particularly vulnerable.
I think we have reached the stage where we can limit vaccination to older adults and those vulnerable for whatever reason.
