>> do you have a sense of what the timetable is for approval for younger elementary school aged children? yes we are waiting on pfizer to actually file the beginning of the emergency use also right station for ages 5 to 11 literally any day now. i'm sure that will also make news that once that's filed the agency will echo this, they are ready to get the data packet, they are ready to do things as quickly as possible. but oversee the safety. but typically when the agency has done things, in sort of a priority manner, three or four weeks of a turnaround, an fda emergency offer is follow from some of those advisory committees that we witnessed last, week around the boosters on. so we could be looking at first shot may be as early as halloween. but i have high optimism certainly before thanksgiving if all of the safety and efficacy show up to be what the pfizer press release states. >> doctor kavita patel, thank
