Transcript for Is a vaccine still on track for 2021?
Dr, Jen Ashton with answers to viewers' questions. Is the vaccine still expected to be ready by 2021? So much attention on that vaccine time line, Amy. The short answer is yes, there's optimism that it can be ready some time in 2021, according to Dr. Anthony Fauci, possibly early 2021. Going back to the time line here, we remember back in the very beginning, 12 months to 18 months is the absolute shortest period of time that a vaccine can go from 0 to being able to be administer, land speed record previously is four years. If we get this vaccine any time in 2021 that will of course break the record, and just because it's fda approved or authorized for emergency use, how many will be able to get it, how it will be allocated not just here in the U.S. But worldwide, we haven't heard any plans about that. There's still a lot that still needs to be determined. We can't cut corners on safety and efficacy. So a lot we still need to figure out. This next question addresses a concern from all pet owners given this headline, what do we know about the dog that's believed to have died from covid-19? Well, we're still looking into it, that's the short answer. This dog was in North Carolina, allegedly it was an 8-year-old Newfoundland. There was a household contact of covid-19 in one of the humans in the household. Right now, again, the CDC and state veterinarians are saying the risk to animals is low, but we have heard cases of this before, we have to remember that animals, especially dogs, to get other strains of coronavirus and they have shown they can be infected with sars cov-2. We're following it. Again, we don't want to think of our dogs being vulnerable. You have to remember the denominator of how many millions and millions of dogs there are in the U.S. Next question, should we expect to see an uptick in covid-19 cases in the fall and winter as more people spend time indoors? So that is the major concern right now amongst epidemiologists, infectious disease specialists, and public health officials. Obviously, we've seen massive cases in the summer months when people are outdoors, when people go inside, of course that's the big concern. Silver lining is, we may see less influenza because of all these social distancing, mask wearing, hand hygiene measures. We don't know yet. But the key -- if you're indoors, ventilation, ventilation, ventilation, if possible, keep those windows open as much as you can. Thank you so much, Dr. Jen.
