Paris lab’s Asturian flu strain developing next year’s vaccine

Asturias was one of the first communities where influenza was detected. This is because temperatures in the area are cooler than other areas, which is conducive to the spread of respiratory viruses. But above all, the principality’s epidemiological surveillance system “always conducts a very active search” for pathogens.

The first strains collected at HUCA have been sent to the headquarters of the Carlos III Health Institute in Mayardahonda (Madrid) for sequencing, and to Paris laboratories already working on a vaccine for next year. “These first strains were collected around the world and will be critical for neutralization studies before developing next year’s vaccine,” the virologist said.

Two type A lineages

Starting from the first cases diagnosed in Asturias, we deduced that the main influenza is type A, specifically the H1 and H3 lineages, which have been included in the vaccine for people over 60 years old, pregnant women, sick people this autumn. .Chronically ill, immunosuppressed and smokers. Therefore, “these strains are similar to those used in the vaccine,” suggesting that the preventive measures used “will be effective.”

However, they point out that “the vaccine does not protect against influenza. It is intended that if you become infected, your clinical picture will be more modest and your ability to be less contagious will be reduced.” Of the immunization campaigns carried out since October 9, six Children between 1 month and 5 years old are also protected from influenza because “their viral load is higher and they are more contagious.” The Ministry of Health purchased non-injectables precisely out of consideration for young children.
