screenings. for patients being told they have to wait for those, oftentimes the surgeries feel pretty essential to them. let s talk about the path forward. we are seeing some paths in europe. people in countries saying we ll move on. what is the path forward for this country? thank you so much for having me. i want to emphasize that the situation in europe is very different from the u.s. they re using a vaccination plus strategy where they re encouraging vaccinations and boosters but they also are, for the most part, enforcing public health measures. they still have mask policies. people have to wear masks indoors. they still have a significant and robust testing infrastructure. they re paying attention to ventilation and air filtration and also provide financial support for quarantine or isolation or sick leave. that s different than the approach that the biden administration is taking which is a vaccine-centric approach.
