"
There is a clear acceleration of the fifth wave,"
said Jean-François Delfraissy, president of the Scientific Council, on France Inter on Wednesday November 17th.
"
She arrives in France, which was the right student with Spain and Italy because of our level of vaccination, but she is there," he
adds.
To date, 74.9% of French people have received two doses of the vaccine, but this does not seem sufficient to guarantee collective immunity.

Seasonality of Covid-19
“
We are in the winter phase where the virus is circulating more, where we are more indoors.
The two differences are the vaccine and the Delta variant, which is much more transmissible,
”observes Jean-François Delfraissy.
“
We also have the Delta variant, which is an extremely transmissible variant.
I don't think we have understood it sufficiently yet.
Including in the medical field.
It is more transmissible,
”he notes.
"Cautious optimism"
"
The forecasts show that we will be able to climb to 1000, 1200, 1400 hospitalizations per day (...) perhaps at the beginning of December
", considers Delfraissy.
We probably have the capacity to cope with this fifth wave, provided we use all the tools.
Vaccinate those who are not, the third dose, the barrier gestures and the application of the health pass
”.

Vaccine efficacy
Vaccines are far from being a failure, for the scientist, but "
you have to know how to use them
" because "
they lose part of their effectiveness after five to six months, hence the interest of a third dose
" and “
Protect relatively little against infection and transmission. So I know it's hard for the public to understand because a vaccine usually protects against transmission. ”
He also maintains that "
it is extraordinary that we had this vaccine so quickly
" and that they "
protect very strongly against the occurrence of severe forms and serious forms
".
