people are fore going tests, if they re traveling somewhere. they don t want to test positive for fear they re stuck somewhere for ten days. we re adding a disincentive to testing, and we could stop that if we have a shorter period. just because you don t know doesn t mean you don t have it. you make such a good point. dr. rodriguez, before we go, the fourth shot for the elderly and immunocompromised that israel is doing, is that going to come to the united states, do you think? well, you know, it might, but i even said this last night, i think israel may be jumping the gun a little bit, and even they said they don t have any data to support this. but they are trying to be ahead of what they think has been a pattern. it neigh come to the united states. i think people definitely not run to their pharmacy or doctor asking for a shot. i think we need more information, but i think repeating vaccinations, whether it s yearly or whatever, is something that is going to happen. dr. wen,
