reality is terrible. a party can be cancelled. doctor, if someone is planning a massive party with people flying from around the country, what would your advice be? >> please don't. you heard dr. collins say at the beginning of the segment our cases are going up. whether you're a democrat, republican or independent, the public health is the same advice, yes, vaccinations can help reduce infections but money -- none of us are immune. hopefully the end is near sight as we get more people vaccinated. >> dr. nahid bhadelia, thank you. adrienne elrod, thank you as well. coming up, this morning the taliban is on the brink of power in afghanistan after 20 years of war and thousands of lives lost. many americans are now asking what was it all for?
