gigi gronvall. dr.nvall, let's start with how bad this is for the vaccinated, especially, here in new york, everyone is seemingly vaccinated, certainly anyone that wants to be and does not suffer from other immune system problems can be vaccinated. is it really that bad? dr. gronvall: it helps to think about maybe how the vaccines work. for your vaccine to protect you, you'll be exposed to the virus and then your immune system is not having any of that, and stop the virus from replicating. you will get exposed. depending on how good your immune response is, it will take you less time or more time, to counter this infection. maybe you don't want to have that experience. maybe some people's experience will be better than others. of course, you worry about those that cannot be vaccinated, and that is everyone under 12. matt: what does the science tell us about kids under 12? how do they react to the coronavirus? dr. gronvall: generally, they do much better than adults, certainly much better than seniors. i
