be good for the 60 plus group. but we don t know how long it lasts. if it works in the 60 plus group, is there a reason it would not work in the 20 plus group? and by the way, i should point out that israel is vaccinating everybody. i know people in their 20s in israel who have stood in line for an hour just, you know, this week and got the third booster shot. yeah, i don t think there s a question that the vaccine, the third dose would add an level of immune protection for everyone getting it. i think what dr. fast is getting at, it s a different risk calculation of different groups of people. i think we are entering a point in the pandemic where people are making different risk decisions. we see this happening already. some people are saying i m fully vaccinated i m going to resume all of my prepandemic activities. others are saying i will be cautious. same when it on comes to getting a booster dose.
