This came up on our weekly Covid call for our health system. According to our expert, there are no guarantees that the vaccine will grant the recipient any immunity for "X" length of time. She was not able to clarify if a booster would be needed or if annual vaccinations would be 'encouraged' and/or mandated when the vaccine is no longer under emergency approval. So much unknown with this thing, not sure why anyone would willingly inject it into their person as it currently stands.
Some of us wont.
