vaccinated people are not going up at this point. and we're not seeing deaths from it. but i think that the rationale for how the u.s. government is planning on phasing in booster shots, or third immunization at some point, needs to be clarified. now they've said that immunocompromised individuals, those on immunosuppressive therapy are going to require it, but even then they've not specified. we know that the data shows that organ transplant recipients need it but they haven't said, does that mean people on certain medications or certain therapies, maybe five to 7% of the population have some form of immunological issues. do they all need? it and then what about older individuals? and how are they going to phase it in? so it's a little vague right now, a little bit chaotic. and i think people are just responding and saying look, the shots are going used anyway, i might as well just get it.
