More cheers for hospital workers, new york city firefighters joined residents in saluting staffers during shift change at a facility in manhattan in what has become a nightly ritual. Turning to the new hope on the front lines in the race for a vaccine. Only a few Human Vaccine studies are under way in the world but one of them at university of philadelphia is showing new promise. Brian taft has that story. Reporter the race to develop a covid19 vaccine in philadelphia is kicking into high gear. Dr. Pablo tevas is leading the second u. S. Vaccine study in people at university of pennsylvania, one of only five Human Vaccine studies around the world. This is the most important study that i have done in my life. Reporter he is testing a skindeep shot on 40 volunteers and says phase one should be wrapped up by july. You have a vaccine that can be distributed in the general population, vaccinating largest amount of people. It would probably take a year to 18 months from now. Reporter more than 70 vaccine studies are under way right now worldwide. The first u. S. Study on people began last month in seattle developed by the National Institutes of health. The first person to receive a shot returned for a second dose. And the nations leading Infectious Disease doctor, anthony fauci, says so far there are no red flags. The study could move into phase two by june. We have to have something in place that is efficient and that we can rely on. Reporter 29yearold ian hayden volunteered for the trial. My ultimate goal is that through participating in this trial, i can play some small part in helping to end this pandemic sooner. Reporter obviously everyone would prefer this be over sooner rather than later. But should this drag on into the summer or into the fall, medical experts think some of these larger studies could be wrapped up mid to late winter, so a longer road to the virus could lead to a shorter road to the vaccine. Thanks to our friend brian taft and wpvi there. A lot of work is being done to find the vaccine. I will say that i do hope that other diseases and viruses and things, research that is going on for them, is not going by the wayside as we obviously still search for a vaccine for covid19 as well.

But we must begin with the latest developments in the coronavirus crisis. President trump reversed course a day after declaring that he had total authority over the states to reopen the country. He now said hes leaving it up to the governors to ease restrictions as they see fit. Plans to eventually lift stayathome orders were already in the works in several states, including california, where the governor is envisioning a new normal with widespread testing, disposable restaurant menus, and masked waitstaff.

I will be speaking to all 50 governors very shortly, and i will then be authorizing each individual governor of each individual state to implement a reopening. Reporter but the constitution says governors dont need the president s authorization because states are given Police Powers during a Public Health crisis. The president says at least 29 states could reopen beforehe others, like california, which was the first to issue a stayathome order, are gearing up for a long, drawnout reopening process. Governor gavin newsom unveiled his guidelines. Normal it will not be. At least until we have herd immunity and we have a vaccine. You may be having dinner with a waiter wearing gloves, maybe a face mask. Dinner where the menu is disposable. Where the tables, half the tables in that restaurant, no longer appear. Where your temperature is checked before you walk into the establishment. Reporter newsom says it could be months before largescale events are held, and widespread testing will be crucial. Dr. Anthony fauci says when it comes to testing, we have a long way to go. To me, we have to have something in place that is efficient and that we can rely on. And were not there yet. Reporter hours later, trump claimed testing is now the governors responsibility, not the federal governments. But he assured americans that states will reopen safely. We want them to do their testing. We want them because theyre equipped to do testing. Dr. Fauci said this morning that critical testing and tracing ability does not currently exist.
