70% of people over the age of 65, aka the most vulnerable people, receive the flu vaccine according to your link. I would like to add that they are vulnerable for a few reasons-- the first being that being old is correlated with dying from covid, the second being that old people are more likely to have been pack a day smokers, and the third being that old people are more likely to have heart disease.
