On July 15, the Directorate of Research, Studies, Evaluation and Statistics (DREES) published the contamination figures in France. These results confirmed that four out of five new cases of infection involved unvaccinated people. This data covered the week of June 28 to July 4 with, on average, 2,120 daily PCR tests tested positive during this period.

The vast majority of these new positive cases concern unvaccinated people (1,700 positive tests per day). The fully or partially vaccinated correspond respectively to 130 and 230 new cases daily“, adds the DREES in its analysis. Conversely, only 6% of new positive tests relate to fully vaccinated people. By restricting itself to only patients declared symptomatic, the proportion of fully vaccinated tested positive plummets to 4%.

The Institut Pasteur also looked at the contamination figures. According to their models, a vaccinated person would be twelve times less likely to infect others. This study is based on a prospective vaccine coverage scenario of 30% in 12 to 17 year olds, 70% in 18 to 59 year olds and 90% in people over 60, as well as an initial reproduction rate. of the virus (R0) of 4. The study indicates that, in the studied scenario, unvaccinated people would represent 37% of the population but 75% of infections.
