According to vaccine experts from the Centers for Disease Control and Prevention (CDC), 15 people in the United States have experienced severe blood clots after receiving the Johnson & Johnson new crown vaccine, and 3 of them have died.
According to the Associated Press and other US media reports, on the 23rd local time, vaccine experts from the US Centers for Disease Control and Prevention stated in the meeting materials that there have been 15 reports of thrombosis involving Johnson & Johnson vaccine in the United States, of which 3 have died and 7 are in hospital. After treatment, 5 cases have been discharged. These 15 patients with thrombosis were all women, and 13 of them were under 50 years old. In addition, 12 of these 15 cases involved rare cerebral thrombosis.
It is reported that, despite the risks of vaccinating Johnson & Johnson, the US Food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention announced on the 23rd that the suspension of Johnson & Johnson’s new crown vaccination ban was lifted. Earlier, the US Centers for Disease Control and Prevention's Immunization Practice Advisory Committee voted to recommend the resumption of Johnson & Johnson's new crown vaccine. Committee members believe that the advantages of the vaccine outweigh the risk of serious blood clots associated with it, but some members expressed concern that the vaccinated people will not fully understand This rare but potentially dangerous, or there are other vaccine options. There is controversy as to whether to add additional warnings for women under 50.
Beth Bell, a clinical professor in the Department of Global Health at the University of Washington, said: "Although I voted for the resumption of Johnson & Johnson vaccination, I am worried that consumers and women of this age will not be able to obtain sufficient information through the FDA's emergency authorization instructions."
