The effectiveness stats for pf vs AZ can be misleading. Both offer similar protection against going to hospital. have to double check against the delta one, but remember still very good, more than worth taking. AZ is made here, walk ins are available apparently, have been for a coulple of months. Trouble is though its a while before second does and max protection. People in there 70s or 80s have few % chance of dying, so yes it is a worry people like that would wait. A 5 or 10% chance at dying vs an incredibly rare complication of clotting. Its going to be very sad if someone in there 70s dies "waiting for the other vaccine".
