The purpose of the pause in the vaccine’s use is to determine if there’s any association, and the strength of the possible association, between the vaccine, the health of the six affected women and the clotting disorder. Having this information will help screen patients. Also, to be reviewed is what about the vaccine may have caused the disorder. According to the CDC, the number of cases at this point is too small to determine specific risk factors that might predispose someone to the clotting problem.
This clotting issue is very rare; fewer than one in 1 million people have experienced it after receiving the J&J shot.
The great majority of people who have received the J&J vaccine have not experienced any harmful side effects. According to the CDC, if you received your shot over a month ago your risk is very low and you don’t need to take any specific action. If you have concerns, consult your health care provider.
If you received the J&J vaccine within the last month and develop any of the following symptoms within three weeks of receiving your shot, you should contact your doctor or seek medical treatment: severe headache, blurred vision, fainting, seizures, abdominal pain, leg pain or shortness of breath. Mild fever, mild headache, fatigue and joint or muscle pain after vaccination are routine and typically go away within two to three days.
Furthermore, this pause in the use of the J&J vaccine means that the vaccine safety monitoring system is working. Responding to the pandemic has required many difficult decisions on the part of federal experts. They are working to balance vaccine safety while also vaccinating Americans as quickly as possible.
