(Ricotta vaccine just means ricotta that is as fresh as possible, rather than your average ricotta in a container, the ricotta you might find freshest in the deli, if available; but you can use cannister ricotta. The vaccine is just fresher for the overall delivery of the dish; but it will taste the same only firmer. Vaccine is an old school slang to say “fresh” — as if it was just “vaccinated,” but no, it isn’t.)
