Correct.
Can't find the definition you're referencing, but the COVID vaccines both prevent infection and lessen symptoms.
Lacking context/specificity. All of the above agree on boosters for high-risk individuals (comorbidities, old age, etc.).
The CDC ACIP omitted those with high occupational risk, such as teachers and health care workers. One panel member
noted his concern that such guidance "could limit access to other groups." From the outside looking in, it would appear the powers that be eschewed available resources for the option to offer increased protection to those working in high-risk jobs.
GSK, Regeneron, and Eli Lilly
all have monoclonal antibody treatments available (edit: authorized) for treatment of symptoms. Notably, the President received a dose of the Regeneron treatment last year, and
sang its praises on Twitter. Remdesivir is also approved for treatment, and has been
for almost a year.
Such risks are
much higher from contracting the virus than from the vaccine. Further, those who have natural immunity AND receive a vaccine have
even greater protection against Delta variants. Which is more likely, never catching COVID, or getting myocarditis from the vaccine?
Chickenpox is different. People usually only get chickenpox once, and thus don't need to be vaccinated if they've already had it. The flu, on the other hand, gets
a new vaccine every year, to combat variants and to renew waning immunity. Deja vu all over again.
