The Food and Drug Administration on Thursday announced it was limiting access to Johnson & Johnson’s Covid-19 vaccine because of the risk of a blood clotting disorder that was discovered weeks after the vaccine was first put into use in the spring of 2021.
Going forward, the single-dose vaccine will only be available to people 18 and older who cannot take one of the other available vaccines for medical reasons, or who simply will not agree to be vaccinated with one of the messenger RNA vaccines made by Moderna and by Pfizer and its partner BioNTech.
