Nearly three million French people have been positive for Covid-19 since the start of the epidemic in March, probably much more in reality. Is it useful for these people to get vaccinated? If you have recently contracted the disease, it would be useless, because a priori, you still have antibodies. On the other hand, after a period of three months, there is debate. It is in any case medically possible.
In fact, the duration of the long-term immunity conferred by the Covid-19 is currently not known. “The US data we have puts the cursor at six months, knowing that the latest most recent data shows that for people with symptomatic symptoms, immunity works at 95% for eight months at least “, ie the entire period that has elapsed since the start of the epidemic, recalls the infectious disease specialist Benjamin Davido on RTL.
So the answer is that there is no emergency get vaccinated if you have been sick before, even if you have over 75 years.
