In the Nord and Pas-de-Calais, 1,200 doses of AstraZeneca did not find takers in the vaccination centers this Easter weekend. “It’s more than a wind of panic“: the mayor of Calais Natacha Bouchart told AFP on 5 April to have”550 doses of AstraZeneca to be sold“and only have about 70 appointments scheduled for the next few days, while the slots for other vaccines fill up easily.

Hundreds of canceled appointments

According to France Blue, hundreds of appointments were canceled in the vaccination centers of Calais, Gravelines and Boulogne-sur-Mer on Saturday and Sunday.

In Gravelines (North), doctor Thierry Mraovic, one of the coordinators of the Sportica vaccination center, said on his Twitter account that 600 unused doses had to be returned, deploring that “the current criteria for the AstraZeneca vaccine (are) now limited to the population over 55 years of age“.

Same difficulty at the vaccination center at the Marcq-en-Baroeul racecourse (North): “When 500 appointments are online for the Pfizer vaccine, they go in five minutes, whereas with AstraZeneca, it takes a day and a half, or even two days.“note the officials.

Benefits far greater than the risks

At issue: the fear linked to the rare cases of thrombosis which have occurred in people vaccinated with AstraZeneca. However, the benefits of the vaccine remain far greater than the risk of thrombosis. In other words, the benefit-risk balance of the vaccine remains largely favorable to the vaccine.

Indeed, according to latest laboratory data, the vaccine would have an efficacy of 76% against the symptomatic forms of covid, an efficacy of 100% against the severe forms and of 80% in those 65 years and over.

And according to figures recorded in Europe and the United Kingdom, cases of thrombosis represent one death in 2.5 million people vaccinated. If these 2.5 million people had not been vaccinated and had caught covid, between 2,000 and 50,000 of them would have died, because the lethality of the virus varies from 0.8 per 1,000 to 2% depending on the age.
