“We have proof that the vaccines are very effective in preventing hospitalizations and deaths.”
Do you have link to this proof that the vaccine is effective since you stated “We have proof”?
Who is “We”?
Is this an account for some type of group on the internet?
It’s possible that the vaccinated individuals who did not require hospitalization were generally healthy, while non-vaccinated individuals who were hospitalized may have had underlying health conditions similar to those of hospitalized vaccinated individuals.
