Transcript for When will there be a COVID-19 vaccine for children?
Dr. Ashton, to bring you in here, our viewers have some questions for you. Question number one, what is the latest on the Johnson & Johnson vaccine that only requires one So much hope hinging on this. We should be hearing data soon. They should be submitting it to the fda in the next couple of weeks, as per Dr. Anthony Fauci. Yes, it is a one-dose regimen, which would obviously be massively helpful from a logistical standpoint. And published data from the earlier clinical trials in "The new England journal of medicine" shows by day 57, 90% of the participants who got this vaccine had neutralizing antibodies that persisted and remained stable at least until day 71 which is when they stopped collecting data. But they of course will continue to follow for a year. Important to understand. Right now, it looks safe and effective, but remember, this is why when people say when I get the vaccine, can I just go out without a mask on? The answer is no, because remember, when they test these vaccines, they're looking at a certain point, and then they're submitting that data to the fda. So we don't know if by three months, four months, six months, ten months, the antibody levels may wane. We don't think they will but you cannot assume when you're talking about science. Learning as we go for sure. Next question, when will there be a vaccination that is safe for children and how do researchers determine it is safe? Great question. And again, I have spoken to Dr. Fauci about this. They are conducting what is known as bridging trials. So they don't have to completely reinvent the wheel then they're talking about these clinical trials but they're starting to look at it in younger children down to age 12. They have to make sure that it's safe and effective. Maybe with the same dose, maybe with lower doses. The estimates, fingers crossed, are that children may have a vaccine that's authorized by the fda, at some point this summer. Keep your questions coming to Dr. Jen, at her Instagram, @drjashton.
