Transcript for Will children be the last ones to get a COVID-19 vaccine?
All right, Dr. Jen Ashton here with us answering your coronavirus questions. Let's start with the first, is it unusual for three different effective vaccines to be approved and released around the same time? Well, yes, it's unusual historically in the world of science and vaccine development. This is unprecedented. We've never seen global collaboration of this magnitude and we've never seen from the clinicals and manufacturing occur at the same time. So a lot of time has been saved. Safety and efficacy hasn't cut corners because that can't be shortened. At least four developers in phase 3 clinical trials that are U.S. Companies, at least ten worldwide, so we'll hear more. We have more questions about the vaccine, this next one, how should we determine which vaccine to get? So many people asking this question. Here's what I think it's going to come down to in reality, because, again, we don't have a lot of information yet about the rollouts. States will be working on that with some assistance from the federal government, but largely it will be determined by which vaccine will be available for you, for you, where you live, what group you're in, I don't think initially we'll be able to say, well, I want the modern vaccine or I want the pfizer vaccine. It will be which one ships to your area, because, again, access is the name of the game. One more here having to do with kids, will children be the last people to receive the vaccine? At this point, largely, it looks like they're in last group. I've been in touch with the fda about this, asking about when the clinical trials for younger children will begin. They're talking about that right now. Once the vcinemakers get eua from the fda, then they'll set their plans in place to enroll children of all ages in their clinical trials, largely that will be starting in the beginning of 2021, because some of these vaccine developers only studied down to age 16. Some down to age 12. They need to enroll children down to months of age. So that will be happening early next year. Dr. Ashton, thank you.
