Actually a lot of younge people get the flu shot every year. I know my kids usually do. A lot of people under 50 do as well.
In addition if you look at the data, a lot of the spread in Covid is in people under 50. Vaccinating younger people is what is needed to stop the spread. Older people may have more serious outcomes, but they aren’t the ones spreading it.
we will never stop the spread, scientists are now speculating that this will be endemic, what we need to do is focus on the number of deaths and hospitalizations at this point, not the number of cases. We also need to transfer our system from being people who died and had covid in the last two weeks, to people who died from covid for the sake of accuracy. Cases would mean nothing if people weren't dying or being hospitalized. As for kids who get vaccinated for the flu, the number is about 20% for all age groups 12 to 45, for 45 to 65 its about 35% and for over 65 its 65%. So no I wouldn't say that a lot of kids get it. To me 1 in 5 isn't a lot, its an extreme minority. 80% would be a lot, not even the 65+ crowd is at that level. Eventually it gets to the point where as vaccines are more available to folks over 65 we need to transition back to the individual being responsible for their own health, not the group or the government.
