And this issue, as was stated in the introduction, was something towards vaccinations and how I was not immunized against various diseases, including polio and measles, as well as influenza, HPV, hepatitis -- the standard vaccine someone my age would receive.
И эта проблема, как было сказано вначале, связана с прививками и с отсутствием у меня иммунитета к различным болезням: полиомиелита, кори, гриппа, ВПЧ, гепатита — стандартные вакцины, которые  получают люди моего возраста.
