At the microphone Without appointment On Monday, Europe 1, Augustine heard from the Metz that it was his Doctor He confirmed to him that he had been immune for two months Kovid-19 Last January and he can also develop antibodies for a long time. However, with the appearance of the variants, he wonders if he really has immunity. Doctor and columnist Jimmy Mohammed answers him by pointing out the things we know about immunity and what variations change after coronavirus infection.
How long does immunity take after a coronavirus infection?
“Studies show that – so it may change over time – after a coronavirus infection, you develop antibodies for at least nine months. This is average. Some patients, especially asymptomatic and older ones, may develop antibodies. In existing patients, antibodies may be produced longer.
So it doesn’t make sense to play too much over time. You need to be vaccinated as soon as possible to get rid of this virus.
Are there personal differences?
Absolutely. There are individual variations. Again, just because you don’t have more antibodies doesn’t mean you are no longer protected … it can be a lot more complicated than that. What we do know, however, is that children develop twice as many antibodies as adolescents. The latter develops twice as well as adults. As we age, our immune system becomes less efficient.
How does it change the appearance of variants in relation to immunity?
Redistributes the cards in the form of variants. With the English variant, the immunity acquired with the first strain of the virus seems to be stable. On the other hand, South African and Brazilian varieties, representing 5% of PCR tests, are in the minority, providing a slightly more severe infection. After all, it escapes the old immunity. If you caught the coronavirus a month or two ago and looked at these African or Brazilian variants, you would get sick again.
Also, sooner or later, there will be variations trying to escape the immunity specifically given by the vaccine.
How long should you be vaccinated after infection?
First of all, it is important to remember that the immunity given by the vaccine is clearly more effective and lasts longer than the immunity given by the infection. When you have Kovid and the disease is diagnosed by PCR test or serological test, you have to wait three months before vaccination. The current recommendation says that a single dose is sufficient in this case. Things are more likely to develop when we have a little more vaccines … Currently, this is a dose three months after the infection. “
