83% of people hospitalized, twelve times more likely to end up in intensive care, positivity rate three times higher ... A study published Friday by the Directorate of Research, Studies, Evaluation and Statistics (Drees ), studies hospitalizations linked to Covid-19 according to vaccination status.
"At the end of July, the entries in critical care are twelve times less within the population completely vaccinated than among the unvaccinated people",
writes thus the Drees.

The organization obtained these results by combining information from databases on screening, hospitalizations and vaccinations, until July 25 inclusive. This data will then be updated every week. According to the Drees, between July 19 and 25, 87% of people admitted to intensive care and 83% of patients admitted to conventional hospitalization were unvaccinated. By comparison, unvaccinated people accounted for 85% of hospitalizations in intensive care between May 31 and July 11 and 84% of admissions to
“conventional”
hospitalizations
, according to a previous study by Drees.
As for people who were fully vaccinated - those who therefore received their two doses - they represented 6% of critical care admissions and 11% of conventional hospital admissions.
The Drees also adds that in the "ratio" of deaths, 14% were fully vaccinated and 82% were not.
In the general population, the share of unvaccinated people was 45% and that of fully vaccinated people 39% at the time of the study.
Three times higher test positivity rate for unvaccinated
"What really matters is the proportion of the vaccinated population that is hospitalized versus the proportion of the unvaccinated population that is hospitalized"
, however, underlined Guillaume Rozier, founder of CovidTracker and ViteMaDose, on Twitter. The engineer thus compared a random group of 10 million unvaccinated people to 10 million fully vaccinated people. According to his calculations, 72 people were admitted to the hospital from the unvaccinated group and 7 from the vaccinated group.
La Drees also undertook the same process but with a sample of one million people in each group.
"The entries in critical care amount to 9.1 patients per 1 million unvaccinated and 0.8 per million fully vaccinated between July 19 and 25",
writes the organization which concludes:
"Thus to comparable population size, there are twelve times more people entering critical care among the unvaccinated than among the fully vaccinated ”
.
Critical care entries and deaths of patients tested positive per million inhabitants between July 19 and 25.
The Drees
Regarding the positivity rate of the tests of the unvaccinated, between July 19 and 25, the Drees indicated that it was
"three times higher than that of the vaccinated".
It amounts to 258 positive tests per 100,000 inhabitants against 35 per 100,000 inhabitants for the vaccinated. A difference which can however be explained by
"the absence of need to do a test for these people in the event of activity requiring a health pass".
The figures of the DREES are also lower than the data of hospitalizations at the national level since the organization studies only the admissions and deaths of people tested positive whose age and sex are known.
