Transcript for CDC director talks Delta variant, rare heart inflammation in young vaccinated people
is the director of the CDC, Dr. Rochelle walensky. Good morning to you. It's good to have you. I want to start with myocarditis. There are now more than 300 cases being investigated. That's out of millions of people who have been fully vaccinated. Is there enough evidence to officially confirm the link between the vaccines and this rare condition? Good morning, whit. Thanks for having me. We certainly are looking at this carefully. We have an acip meeting scheduled for next week. We're going to be eager to look at the data during that meeting. What I will say is over 200 million doses of vaccine have been given. Really these events are quite rare. They are minor, self-limited. They generally resolve with rest and standard medications. What we're saying the risk of the disease itself -- we've had 300 pediatric deaths. We've had over 4,000 children with the mic syndrome that resulted in 30 more deaths. We're saying in that context these cases of mild heart inflammation, the risk of that which are quite rare, are overwhelmed by the benefit of getting vaccinated. We know it's rare and that's your message to parents. Many are still on the fence, trying to weigh these risks. How would you bring that message to them? What I would say, first of all, I have three kids. All are vaccinated. The most important thing you need to do is be comfortable as a parent with your choice in making this decision. If you make an informed decision where you listen to the science around the vaccines, the safety of the vaccines, the overwhelming data we have and how effective they are at preventing severe disease and sickness in your children, I think you'll come down the way I did and vaccinate your children. I want to turn to the delta variant. We know it's highly contagious. Identified in 41 states in the U.S. Do you expect it will become the dominant strain here, and if so how soon? Yes, I think that's probably going to be the case. It's the dominant strain in the uk. When these viruses mutate, they do so with some advantage to the virus. In this case it is more transmissible. It's more transmissible than the alpha variant or uk variant we have here. We saw that quickly become the dominant strain in a period of one or two months. I anticipate that's what happens with the delta strain. We know the vaccines have been effective against this variant. It's already mutating. Is it only a matter of time before there is a strain more resistant to our vaccines Certainly that's what we worry about and what we're trying to avoid. We do know as vice president they do that, they do it with advantage to the virus. I will say as worrisome as this delta strain is with regard to its hyper transmissibility, the vaccines work. They require two doses to be fully vaccinated to work well. I would encourage all Americans to get your two shots and you'll be protected. Vice president kamala Harris is on a bus tour to encourage people to get vaccinated. Is this needed to reach president Biden's goal to reach 70% by July 4th? We only have a couple weeks to get there. This is one of many things we're doing to try and reach that goal and to go beyond that goal. I think this is one of many strategies. We have rides. We have child care. We have incentives. We're trying to meet people where they are and provide the oompf they need to get vaccinated. I'm excited to be with the vice president at the ebenezer church. Dr. Walensky, thank you for your time. Voters are going to the
