Reporter its 8 30 in the morning, and each child stands inside a hula hoop with their supplies until its time for their teachers to bring them into the classroom. This is preschool in times of covid19. And i have to say, the children act as though none of that mattered at all. Reporter inside the classroom, all of the desks are spread out and spaces clearly marked. Each child is allowed to only use his or her own supplies. Anything they share is immediately sanitized. Still, the preschool acknowledges that one of the Biggest Challenges continues to be reminding kids to social distance. Arms length, kids arms length wherever we can have them social distance, we will. Eating, playing. If theyre doing something individually, they have their own materials. So at that point they can be apart. Running on the playground, no, they just og with that said, have you had any cases of covid . We have not had any cases of covid, none at all.

Radio city music halls Christmas Spectacular starring the rockettes has canceled its annual show due to covid19 for the First Time Since it started in 1933. 350 workers are also being laid off. That new Development Comes on the heels of an Exciting New Development in the rush for a vaccine. I spoke earlier with dr. Alok patel. Lets start with testing. For the first time, several states are joining together to form a compact on testing in hopes of reducing wait times. Right now seven states from louisiana to massachusetts have signed on. What do you make of this new bipartisan effort . First of all, i like the fact that its bipartisan, showing us that fixing Something Like testing requires people getting together, ignoring the politics. Also, i think its sad that we even have to get to the point that states need to get together to figure out how to lift the burden over private lab groups, figure out they cannot run out of chemical reagents and fix these issues. It will be interesting to watch did and see what their plan is, see it unfold, see if other states figure out how to work together, or if we can adopt their strategy together as a nation. We got encouraging news about a possible vaccine. What are you hearing about the early trials of novavax . What im hearing is good news from their phase one trial. Not only did their phase one trial show a modest tcell response, it also showed that people who received the vaccine developed fourtimes the amount of neutralizing antibodies as people who naturally got coronavirus, which is great. Because we want to know the vaccine provides more protection and longer protection than actually going and getting the real virus. Also, early animal trials came out from this vaccine also, showing that 11 of 12 monkeys who got the vaccine were actually protected against coronavirus. Granted, humans are not monkeys, but thats a good step moving forward. Theyre just in phase one, though. We have six other vaccines in phase three. Hey, more shots on goal mean higher likelihood that were going to get an effective vaccine. Dr. Patel, a lot of people miss going to their favorite bar, favorite nightclub. The mayor of orlando, florida, says bars may not reopen until we have a covid19 vaccine. Do you agree with that . I agree in theory we should be really cautious about reopening and letting loose until we have an effective vaccine. I worry about the statement that i dont know how its going to resonate with people who are already anxious, who already want to get out there. A vaccine, what we know is going to basically save the day, and it could be six months away, it could be longer than that. Also, just a note to everyone out there whos frustrated with businesses being closed, stop going out and breaking rules. You hear stories in florida of people crowding in bars. That is something thats going to cause outbreaks and keep businesses closed. While youre at it, if youre going to reopen anything, try prioritizing essential services and schools, and not bars.
