> If the vaccine is only for very healthy 30 years old who typically does not have any covid symptoms then what's the point? Obviously the point is to vaccinate that group. You cannot seriously be suggesting that at this point, in the middle of a global pandemic, a vaccination is not valuable unless it covers 100% of the population. Right now even a vaccine that would only work for 1% would a a useful improvement over status quo where no-one is immune except previously infected. That said the Pfizer-BioNTech vaccine will work for a much much larger part of the population and potentially allow us to reach herd immunity even if a small part of at risk individuals will not be able to take it. That will be a huge benefit to those people even if they don’t get vaccinated themselves.
