The U.S. food and drug authority, the FDA, announced Thursday that emergency use of the Johnson & Johnson coronavirus vaccine is limited to adults where other immunogens are inappropriate or available. access, or to those who choose it because otherwise they would. not vaccinated.
As specified in a statement from the FDA, the restriction is due to the risk of an uncommon and potential dangerous coagulation which may appear after applying the vaccine, called thrombosis syndrome with thrombocytopenia (TTS), as reported by the AFP.
The single-dose vaccine is less protective than that made by Pfizer and Moderna, and in December the Centers for Disease Control and Prevention (CDC) advised the public to avoid using it.
The U.S. watchdog’s decision was based on that recommendation by limiting emergency use authorization for the J&J vaccine. “Today’s action demonstrates the strength of our safety monitoring systems and our commitment to ensuring that science and data guide our decisions,” FDA scientist Peter Marks said in a statement.
On March 18, it was reported 60 cases, and 9 dieddue to thrombosis with thrombocytopenia syndrome (TTS), which produces uncommon and life -threatening blood clots with low levels of platelets in the blood.
Symptoms begin approximately one to two weeks after vaccination and usually occur in premenopausal women.
Concerns about the vaccine led to only 18.7 million doses of the J&J vaccine being administered in the United States, approximately 3.2% of the national total of 577 million.
However, this was not completely denied by the FDA, and Marks acknowledged the impact of the ban on global vaccine use.
Although rare cases of heart inflammation in adolescents and young men are usually transient and most sufferers recover completely, resistance to mRNA vaccines has also been raised generally by anti-vaccine groups and linked to conspiracy theories.
Although such reservations are not evidence-based, the exemption from the use of J&J injection extends to those “with personal concerns about receiving mRNA vaccines who may not receive the COVID-19 vaccine,” it said. conclusion of the FDA statement.
