Washington – American federal health authorities have called for an immediate stop to the use of the Johnson & Johnson vaccine against Covid-19, after 6 cases of thrombosis were recorded two weeks after the vaccine. In all cases, these are women between 18 and 48 years old. One woman has died and another is hospitalized in serious condition in Nebraska. The ‘New York Times’ reports it.
The CDC and the FDA recommend a “pause in the use of the Johnson & Johnson vaccine as a measure of extreme precaution” pending the convening of the Advisory Committee on Immunization Practices tomorrow, “to analyze” the cases of thrombosis which occurred for at least six vaccinated women. The US drug agency will then analyze these “data and investigate these cases,” reads a statement released today by federal agencies.
“This is important, in part, to ensure that the healthcare community is aware of these potential adverse reactions and can prepare to recognize and manage them appropriately given the particular treatment required for this type of blood clot,” continues the statement of Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research and Anne Schuchat, principal deputy director of the CDC, who point out that these “incidents are extremely rare”.
“As of April 12, over 6.8 million doses of the Johnson & Johnson (Janssen) vaccine have been administered and the CDC and the FDA are reviewing data on six reported cases of rare and severe thrombosis,” the two researchers write again.
“The Johnson & Johnson vaccine is similar to the AstraZeneca vaccine, and unfortunately the side effects could also be similar” wrote on twitter Roberto Burioni, virologist at the Vita-Salute San Raffaele University in Milan, after stopping the Janssen vaccine from the FDA. “It is essential – Burioni underlines – to carefully monitor and pay particular attention to communication”.
