Covid-19: the United States limits the use of the Johnson & Johnson vaccine for adults

The Johnson & Johnson vaccine is one of three licensed Covid-19 vaccines for people aged 18 and over. But the United States Medicines Agency has announced that it wants to limit Johnson & Johnson’s Covid vaccine to only adults who refuse to be vaccinated with Pfizer or Moderna because of “personal concerns”, as well as those who cannot receive a vaccine. injection of these last two vaccines for medical reasons or of limited access.

The reason ? The FDA said its analysis determined that the risk of thrombosis with thrombocytopenia syndrome after administration of the injection warrants the limitation of the authorization. For this same reason, the country’s main public health agency, the CDC, had already recommended in December that Americans get vaccinated against Covid-19 with Pfizer and Moderna, rather than with Johnson & Johnson.

3% of total doses injected in the United States

The FDA has identified 60 confirmed cases of thrombosis in the United States, including nine deaths. Just under 19 million doses of Johnson & Johnson’s vaccine have been administered in the country, or about 3% of total doses injected. “The frequency of these thromboses is thus 3.23 per million doses administered”, detailed the American agency.

Still, “we recognize that Janssen’s Covid vaccine still has a role to play in the response to the current pandemic,” said FDA official Peter Marks. In the meantime, the FDA said it will continue to closely monitor data on all vaccines. “Our action reflects the robustness of our surveillance system, and our commitment to ensuring that we follow science and data in our decisions,” said Peter Marks.
