HOUSTON – Numbers compiled from the CDC paint a demographic picture of exactly who has received the COVID-19 vaccine so far. But how do the numbers behind the numbers add up? Ho pointed out that the two groups targeted for the initial rollout were healthcare professionals and senior citizens in nursing homes. She said since about 75% of the medical field is female, it makes sense that more women have been vaccinated at this point. Ad“Usually what happens is that if men need assistance in their older age it’s usually their wife taking care of them and then it’s the women,” Ho said.
