Didn't say "took polio vaccine".
He said he "took multiple polio vaccines".
The plural makes all the difference here.
Eg
I watched the movie.
I watched many movies.
"I watched movie" would be incorrect.
The OT's Grammer is correct.

My family, unfortunately, overrepresents people in America who have not taken it. My mom may be the only one of her siblings who had it, and it was after I was born.

In 🇬🇧 the polio vaccine was routinely given to children orally, dripped on a sugar cube. Had a booster many years later, straight ..... yuk 😖! So 'took' is correct.
@MDaware
As a Briton I know we are actually saying "he was in the hospital", only 'the' is silent.
Also, we haven't had a Polio case in the UK since the 90's because we still vaccinate against it as it is still spread in the rest of the world.
