Transcript for CDC weighs in on rare heart inflammation following COVID-19 vaccine
The clock ticking, thanks. The coronavirus emergency and the CDC weighing in on that rare heart risk. The vaccine and young people. CDC director Dr. Rochelle walensky is joining us exclusively in a moment but first to elwyn Lopez right outside the CDC headquarters with the latest. Good morning, elwyn. Reporter: Hey, good morning, Cecilia. The fda plans to add a warning to those mrna covid vaccines, this as the nation's top infectious disease expert warns a more contagious variant of the virus could become the dominant strain in the U.S. Within weeks. This morning, despite finding a likely association between the pfizer and modern vaccines and a rare mostly mild heart inflammation in younger people, a CDC panel says the benefits of a covid-19 vaccine far outweighed the risk. When they did happen, they were really quite mild and majority of the patients recovered quite nicely. Reporter: In a joint statement the CDC, HHS and more than a dozen health associations calling instances of myocarditis after vaccinations extremely rare and CDC data reporting 323 confirmed cases in those 29 and younger, out of 26 million shots. Finding it happens mostly in young men, about a week after the second shot. The CDC advisory group warning myocarditis is more likely if you get covid and that it will be more severe than if you get it from the vaccine. This comes as the more contagious strain of the virus is spreading across the U.S. The delta variant now in at least 48 states. The spread of this variant a concern in areas with low vaccination rates, renewing the push from health experts to get more Americans to roll up their sleeves. The worst might be to come if you've not been vaccinated at all. You're at risk of serious problems. Reporter: This 34-year-old unvaccinated now hospitalized with the virus urging others to get that arm to needle. This is not a fun disease. It's not something to take lightly. For the people who still think it's like the flu, it's not. Oh, boy, is it not. Reporter: Here at the CDC they say there's no evidence yet to suggest that a covid-19 vaccine booster is needed but, of course, that could change as the pandemic evolves, Cecilia. Joining us is director of the CDC, Dr. Rochelle walensky.
