kitten corner: vaccine risks

i am just a kitten and not a big important CDC health official, so please forgive me if my math is not up to such complex calculations but:

if the rate of post vaccine infection is 0.008% (1 in 12,500)

and those infections are pretty much entirely mild and in older, immunocompromised people, is this really good advice?

because it seems to me like maybe driving to the store to buy more masks is probably much higher risk than that even if you live really close, especially if you are an older person.

i’m not sure if you know this, but many older humans are really bad drivers. kittens get warned about this as soon as we leave the basket. our moms really worry.

thank you.
