No doubt possible for those refractory to the anti-Covid 19 vaccine: the University Hospital Center (CHU) of Bordeaux (Gironde) has just provided proof of its supposed uselessness against the disease.
They rely to do this on a message that was sent recently by the hospital to its staff. “Here is an email received by the 15,000 agents of the Bordeaux University Hospital:” We bring to your knowledge that the majority of professionals currently positive for Covid are vaccinated with a complete scheme “. Hello BFM and Olivier Véran? Why are you saying the opposite? », Pretends to wonder a user relaying the said document.
💉 Here is an email received by the 15,000 agents of the @CHUBordeaux :
“We bring to your knowledge that the majority of professionals currently positive for COVID are vaccinated with a complete regimen.”
Allo BFM🚽 and @olivierveran ?

If we find the sentence quoted in this text, it also specifies: “More than 70 professionals have tested positive over the last 15 days, reminding us that the Delta variant is very contagious. […] It is therefore urgent to recall that community life can have an impact on the continuity of hospital activity and that it is essential to respect barrier measures and more specifically in addition to vaccination ”.
FAKE OFF
This document, that 20 minutes was able to consult, was indeed distributed internally by the Bordeaux University Hospital at the beginning of August. However, there is nothing exceptional about it, as the establishment tells us: “This mode of communication is recurrent in our establishment, we have been managing the crisis for eighteen months with a desire for transparency and regular information from our staff. staff. “
The fact that the anti-Covid-19 vaccine does not protect 100% against contamination – even if it decreases the risks, up to 12 times less according to the Institut Pasteur – but above all against
severe forms of the disease has been known for a long time.
“In a closed population, the more the number of vaccinated will increase, the more in this same population the percentage of positive and vaccinated people will increase, since the vaccine is not 100% effective on the symptomatic form of the disease”, explains To 20 minutes Doctor Fleur Delva, epidemiologist at Bordeaux University Hospital.
“The incidence is much lower in the vaccinated”
“For example, if the vaccine is 90% effective, in a population of 100 people made up of 50 vaccinated and 50 unvaccinated, you will have 55 positive cases including 10% of vaccinated, or 5 vaccinated sick and 50 unvaccinated, so 9 % of vaccinated among the 55 patients. If you go to 90 vaccinated and 10 unvaccinated you will have 10 unvaccinated sick and 10% of 90 sick so 19 cases can occur, including 9 in vaccinated, which would represent 47% of cases ”, continues the specialist.
“We must compare the incidence of the disease in vaccinated and unvaccinated, and not the percentage in the population: we can see that the incidence is much lower in vaccinated, which is in favor of the ‘efficacy of the vaccine,’ adds Fleur Delva.
For the epidemiologist, if “vaccination slows down the circulation of the virus”, the fact that it is “not 100% effective [comme la plupart des vaccins] Implies respecting the barrier gestures while waiting for everyone to be vaccinated. A message identical to the one relayed by the CHU in its internal communication which has gone viral on Twitter.
