Did you get the Johnson & Johnson vaccine? Here’s what to look for.

Health care providers should report any adverse events to the Vaccine Adverse Event Reporting System.

“Right now, these adverse events appear to be extremely rare,” read a joint statement from the FDA and CDC. “COVID-19 vaccine safety is a top priority for the federal government, and we take all reports of health problems following COVID-19 vaccination very seriously.”

Out of the 6.8 million people who have received the Johnson & Johnson vaccine, six women reported a blood clot called cerebral venous sinus thrombosis after receiving the vaccine. All six women were between the ages of 18 and 48 and symptoms occurred six to 13 days after they were vaccinated.
