fda will give pfizer its authorization, so it is no longer emergency use authorization. does that push it over the hump for your patients that have said i don t want to do this. is it a game changer? absolutely. we have a lot of patients on the fence about something that s been developed so quickly. and i think them having the knowledge that this product is approved, will be approved by the fda just like blood pressure medications, inhalers for asthma, i think that will give them confidence to step up. thank you very much for joining us and building on the back end of that, kaiser family foundation study looked at those reluctant to get the vaccine, and asked if it was approved by the fda, would you, and three out of ten answered yes, they would. let s hope at least three out of ten indeed do that. thank you, kerry. dr. patel, i want to go back to the exhaustion doctors are feeling.
