Study says flu vaccine also protects against coronavirus


Waiting the development of a vaccine against Covid-19, a new study would demonstrate the beneficial effects of the flu vaccine. Good news to be taken with a grain of salt.

A two-in-one vaccine?

While the authorities invite people at risk of getting massively vaccinated against the flu this year, in order to do not overload hospitals and make coronavirus diagnoses simpler, this precaution could have unsuspected virtues.

Indeed, according to this Dutch study published on the MedRxiv platform : “the vaccine against influenza may offer partial protection against both infections this winter“. These conclusions have yet to be validated by additional studies because the authors of the study recognize it themselves, “the mechanism behind such an effect is unknown.

Better immune response

Several observations have enabled researchers to advance such a hypothesis. First in Dutch hospitals, where coronavirus infections were less common among hospital staff vaccinated against influenza seasonal during winter 2019/2020.

Then in the laboratory, where the tests in vitro conducted by researchers concluded that the flu vaccine would improve the body’s immune response face au SARS-CoV-2, in particular the famous cytokines – these inflammatory molecules released in the face of a pathogen – thus reducing the risk of cytokine storms which is most often fatal to the patient (a sort of destructive immune runaway).

Seasonal flu causes 10,000 to 15,000 deaths in France. This year, 7 million vaccines would have already been issued and most pharmacies would be out of stock. So do not get vaccinated if you are not at risk!
