During a White House press briefing on Apr. 13 discussing the decision to pause the vaccine’s use, Fauci was asked by a reporter what his medical advice was for people who had recently received the Johnson & Johnson shot and had concerns about blood clots. He was quick to offer reassurance, saying: “If someone recently [received the Johnson and Johnson vaccine], within days, I would tell them to just, first of all, don’t get an anxiety reaction.” He also noted “it’s less than one in a million” chance that blood clotting issues will develop. Besides remaining calm, Fauci also clarified that the 6.85 million people in the U.S. who received the Johnson & Johnson vaccine could look out for certain red flags. But during an interview later that day on CBS Evening News, he explained it was likely not all recipients were at the same risk of this rare complication. “It depends on when they got it. It appears that this adverse event occurs between six days and 13 days. So if you’ve had it a month or two ago, I think you really don’t need to worry about anything,” Fauci explained. “Having said that, you still wanna be alert to some symptoms, such as severe headache, some difficulty in movement, or some chest discomfort and difficulty breathing.” And for more symptoms you should be watching out for, If This Happens After Your Vaccine, the FDA Says You Should Call 911. The top health agencies’ joint recommendation to pause the vaccine’s use immediately raised questions about how the loss of one of only three approved vaccines in the U.S. would affect the ongoing national vaccination effort. But Fauci was confident that regulators would address any issues quickly and that the shot would soon come back into use. “I believe this is going to take days to weeks as opposed to weeks to months,” he said during an Apr. 14 interview on NBC’s Today. “I think we’re going to be hearing about a decision pretty quickly. I don’t think this is going to drag out.” Besides a sudden shortage of supplies, news of the pause had some concerned that the public’s confidence in the vaccination process would be badly damaged. But Fauci was quick to assuage any fears about the shots, telling CBS News, “121 million people have received at least one dose of a vaccine,” pointing out that the vast majority were Moderna and Pfizer with “no negative or adverse or red flag signal” developing as a result.ae0fcc31ae342fd3a1346ebb1f342fcb “In other words, they are very safe,” he concluded.
