Transcript for Johnson & Johnson COVID vaccine paused in all 50 states
We have a lot of news to get to. We'll start with the setback in the race to vaccinate America, all 50 states have paused Johnson & Johnson shots as regulators meet to investigate those six cases of rare but potentially fatal blood clots. So far one death reported out of nearly 7 million shots that have been administered nationwide. J&j now also pausing its clinical trials and delaying delivery of its vaccine to Europe. Dr. Anne Schuchat of the CDC is Stange by to discuss it but first Steve osunsami is at the CDC in Atlanta with the very latest this morning. Good morning, Steve. Reporter: Good morning to you, Michael. A CDC advisory panel will hold a virtual public meeting this afternoon but we expect them to discuss how long this pause will last. Drugmaker Johnson & Johnson this morning is putting a hold on its ongoing clinical trials of its covid vaccine and a hold on the rollout of the vaccine in Europe. They're giving health authorities time to investigate these unusual reports of potentially dangerous blood clots in a small number of patients. I think the important thing to emphasize is that it is very rare. There were six women out of the 6.85 million vaccinations of the j&j, which means that it's less than 1 in a million. Reporter: The government is telling everyone to stop using the Johnson & Johnson vaccine for now, so far there is no evidence showing that the vaccine caused the clots and the risk of being struck by lightning is actually twice as great as getting a blood clot after the vaccine. 1 in 500,000. There's also a much greater risk of getting a blood clot if you remain unvaccinated and get sick with covid. This report from last July looked at more than 3,000 patients and found about 16% struggled with some sort of blood clot. Before people overreact and spin this out of control, we need to constantly think about the risk versus the benefits of everything we do and so far the numbers are very low. Reporter: According to the CDC the six people with these rare blood clots were women between 18 and 48 years old. They all got sick about six to 13 days after getting vaccinated. For five of them their first symptom was a headache, four of them dealt with neurological symptoms like feeling weak and not being able to talk or understand words. One of the six women was hospitalized and died of a brain hemorrhage after experiencing a gradually worsening headache one week after the shot. Another in her late 40s was hospitalized in Nebraska with what doctors say was profound bleeding. The reaction to all of this as Americans scrambling to reschedule appointments after being forced to switch to whatever available supplies there are of modern or pfizer vaccines which have not come with any reports of blood clots. President Biden says that the pause on the Johnson & Johnson vaccine will not keep Americans from getting vaccinated by this summer. There's enough vaccine that is basically 100% unquestionable for every single solitary American. Reporter: The white house, the fda and the CDC are all getting an earful over this. There's a strong feeling that six cases was far too few to pause use of the Johnson & Johnson vaccine and that this will only make things worse, that it will be hard story get Americans to use that vaccine at the same time health officials are warning Americans that if you have any of those severe symptoms, trouble breathing, leg pains after getting the Johnson & Johnson vaccine, that you should call your doctor.
