"5 vaccinations" is dubious, but if Star Moron gopiscrap is old enough (>75, depending on relevant state regs in December 2020), is incorrectly referring to the two dose regime as vaccinations, and received the first of two doses in late December or in January, it is just possible that "5 vaccinations" is plausible. For a sexagenarian or younger following recommended timings, it is not (IIRC, I could not receive a first dose until March 2020 because I'm too "young", and waited until April, courtesy of Covid and my doctor's recommendation).
