AFAIK the only player to have tested positive for COVID in that outbreak is Gleyber Torres (the rest were support staff), who had an actual COVID infection before, which undermines your idea that getting COVID is somehow superior to getting vaccinated.
And as already mentioned, the Yankees received the J&J vaccine, which is not an MRNA vaccine.
