There’s absolutely no way that you can say with any certainty, that it’s safer for your 91 year old mother to be vaccinated, than not, when vaccine has only been approved for emergency use, and has only been developed within a year.
I was talking to someone the other day whose 93 year old mother tested positive with no symptoms. And her 98 year old aunt was sick with COVID. Her symptoms were like a mild cold.
certainty?
no. there is never certainty with any major medical treatment. it’s a probability or risk benefit calculation based on current knowledge. if at 80 with comorbidities you have a 1 in 10 statistical chance of dying from CCP virus and the vaccine has a 1 in 10,000 chance of dying from it, then it’s a no brainer (for me), protect yourself with the vaccine.
on the other hand, if you have a 1 in a million chance of dying from the virus (as a child would statistically per current knowledge). it’s another no brainer not to get the vaccine.
it’s not complicated, if you can take the emotion of fear out of it.
