DECRYPTION – The suspension of the Johnson & Johnson vaccine, justified by serious side effects similar to those of AstraZeneca, is more bad news.
“All adults who wish will be vaccinated by the end of the summer.” This promise of Emmanuel Macron should in all likelihood be kept, despite the serious side effects and the delays that accumulate in deliveries. The latest difficulty, on Tuesday April 13, the American pharmaceutical group Johnson & Johnson delayed the deployment in Europe of its single-dose vaccine developed by its Belgian subsidiary Janssen. The announcement follows the decision by US health authorities to suspend its use in the United States, after the detection of six serious cases of blood clots out of 6.8 million injections. Adverse effects very similar to those seen very rarely following injections of the AstraZeneca vaccine. Both are based on the use of a viral vector, an adenovirus. France reserves the Anglo-Swedish vaccine for over 55s, a group for which the benefit / risk balance remains extremely favorable.
