They didn't. Same amount of vaccines as they would have normally had, since it's the first round.
I was just saying they were severely behind in the interest of full disclosure. I mean, she could've contracted something that could've been prevented by vaccine prior to being vaccinated. I'm inclined to believe that isn't true, since vaccinations are used for super contagious things and her sister didn't get sick. It could also be totally unrelated to vaccinations. I'm not a doctor either.
Oh.
That sucks, but it's a necessary evil -- better than getting much more seriously ill as a result of not getting vaccinated, imo.
