The Covid-19 vaccines made by Moderna and Pfizer was on Thursday, recommended to Americans by the U.S. Centers for Disease Control and Prevention over Johnson & Johnson’s (J&J) jabs due to sometimes fatal but rare cases of blood-clotting.
The decision was made by the CDC following an Advisory Committee on Immunization’s unanimous vote to make the recommendation in favor of the vaccines made by Moderna and Pfizer/BioNTech over the J&J shot
Only fewer Americans have received the J&J shot than the other two. Out of more than 200 million fully vaccinated people in the United States, around 16 million received J&J’s vaccine, according to CDC data.

A statement by J&J said that the safety and well-being of those who use their vaccine is its top priority and it looks forward to working with the CDC on the next steps.
Cases of thrombosis with thrombocytopenia syndrome (TTS), which involves blood clots accompanied by a low level of platelets, have previously been reported in recipients of the J&J vaccine. The highest reporting rates are in women under 50.
The CDC said that the rate of such incidents is higher than previously estimated, both in women and men. The agency has identified more than 50 cases of TTS in the U.S., about 3.83 cases per million J&J doses administered.
At least nine people have died following the blood clotting incidents in the United States, the CDA said.
