Why do you have to keep the mask on, even when vaccinated?

Even if the proportion of people vaccinated is increasing, it is essential to maintain barrier gestures. A vaccinated person can still catch and transmit Covid-19.

Vaccination is progressing in recent days, after Emmanuel Macron announced extension of the health pass, to present for many daily activities. But if it is essential to protect collectively, we should not for all that stop practicing barrier gestures when we have received two doses.

An effective vaccine, but not 100% reliable

Let us remember one essential thing: vaccines currently authorized in France are more than 90% effective in limiting severe cases, recalls the government. But 90% is not 100%.

There is always a risk of getting sick, even when vaccinated. Most of the time, these are mild or symptomatic cases. But it’s not always the case, there are still serious cases detected in vaccinated people, which correspond to less than the remaining 10%. Especially in elderly populations, for whom the vaccine would not have worked, because immunity decreases as the body ages. Other times (fortunately very rare) this cannot be explained in concrete terms, On then speaks of vaccine failure.

You can be contagious, even with two doses

We now know that vaccines can prevent infections, or help the body not to be infected, by strengthening the immune system against the disease.

Imagine that a vaccinated person is infected, he continues to excrete virus, but in less quantity. “Instead of passing it on to 10 people, it is estimated that you risk giving it only to one person”, explains to the Parisian of July 15, Odile Launay, infectious disease specialist at Cochin hospital. But the infectious disease specialist recalls that in front of fragile people (under chemotherapy, immunosuppressed) it is quite possible to contaminate.

Only collective vaccination can put an end to barrier gestures

Must therefore keep barrier gestures. The more people get vaccinated, the less likely the virus will circulate. When vaccination, which is currently the only remedy for the crisis, has reached a certain threshold, and therefore collective immunity will reach 80 to 90%, then the barrier gestures can be reduced. At the microphone of Europe 1, this July 16, the professor of immunology Alain Fischer explained about the end of the wearing of the mask: “It depends on a lot of factors, including vaccination coverage, since it is necessary to tend towards 80%, and the circulation of the virus. All in good time.”
