The panel cited the risk of rare but sometimes fatal cases of blood clotting as well as a lower level of effectiveness against Covid in the J&J shot
A panel of outside advisers to the Centers for Disease Control and Prevention (CDC) on Thursday voted to recommend directing Americans towards the mRNA vaccines for protection against Covid-19 – meaning the shots by Pfizer/BioNTech or Moderna in the US – in preference to Johnson & Johnson’s vaccines, because of the risk of rare but sometimes fatal cases of blood clotting.
The CDC’s advisory committee on immunization voted unanimously to make the recommendation. The regulator still needs to sign off on the guidance.
