As Covid surges in the US, Americans can’t get vaccinated: ‘terrified I might kill somebody’

I can't really figure out how many shots in total should a person in the usa have had today, if he had followed every shot (primary, second, third, combined, boosters)? Someone that knows the correct answer/number? I'm guessing 15?

I guarantee you, the moment a child dies because their parents couldn't get them vaccinated, two adults will become hell-bent on killing someone in charge.
