Another setback for the global vaccination campaign with the suspension announced Tuesday of the anti-Covid vaccine from Johnson & Johnson in the United States and South Africa, and the delay of its deployment in Europe, due to the rare occurrence of serious blood clots.

The American authorities on Tuesday recommended "a pause" in the injections of the vaccine of the American group Johnson & Johnson, while affirming that this would "not have a significant impact" on the immense vaccination campaign, since these doses represent less 5% of those administered in the United States so far.

More than 6.8 million doses of "J&J" have already been administered in the United States and the United States Drug Agency (FDA) is investigating six cases of women who developed severe cases of blood clots after receiving this vaccine.

"One case has turned out to be fatal and one patient is in critical condition," said an FDA official.

"We are very much aware that this is a very rare event. We want to address this issue as quickly as possible," said Anthony Fauci, White House adviser on the pandemic.

The U.S. Centers for Disease Control and Prevention (CDC), the country's leading federal public health agency, will meet on Wednesday to assess these cases.

Canada has chosen to maintain its orders, the first deliveries of which are scheduled for the end of the month.

European countries risk suffering further delays in their vaccination campaign, Johnson & Johnson having announced Tuesday "delay the deployment" of its single-dose vaccine against Covid-19 in Europe.

The EU has signed on to a firm order for 200 million doses of Johnson & Johnson's vaccine, plus an option for an additional 200 million.

The group pledged Thursday to deliver 200 million doses by the end of the year.

In Belgium, the doses already delivered will be "put in the freezer", pending an opinion from the European Medicines Agency (EMA) expected Wednesday, was indicated Tuesday evening within the "Vaccination Task Force". on foot by the Belgian health authorities.

The appearance of these complications is reminiscent of those linked to the AstraZeneca vaccine, on which the European Medicines Agency is investigating, and which has caused strong mistrust against it in the population and the interruption of its use in several countries, in particular Denmark. .

The two vaccines use the same technology using an adenovirus as a vector.

In the case of AstraZeneca, there were on April 4 222 cases of these atypical thromboses out of 34 million injections carried out in the European Economic Area (EU, Iceland, Norway, Liechtenstein) and the United Kingdom, according to the EMA.
