Since August 9, the "health pass" became mandatory in France and applies to many economic sectors and social activities such as commercial catering, trade fairs and exhibitions, healthcare services and medical-social centres, public long-distance transport, and some stores and shopping malls. In addition, since September 30, 2021, the "health pass" has been made compulsory for minors aged 12 and two months to 17 years old. The aim is to better control the spread of the Sars-Cov-2 virus by forcing the entire population to be vaccinated in order to reduce the effects of the epidemic.
Since vaccination is currently the only pursued strategy to fight against COVID-19 in the world, we were interested in verifying the explanation often put forward to justify the improvement (due to high vaccination rate) or the recrudescence (due to low vaccination percentage) of the health situation linked to COVID-19. At the same time, several developed countries have launched the injection of a third dose of vaccines following a substantial increase in COVID-19 cases.
In this regard, we have studied the correlation between the levels of vaccination coverage (percentage of the vaccinated population) and the various epidemiological variables of COVID-19 in the 101 French departments (territories) during the month of September 2021.
The findings of the study indicate no significant relationship between vaccination rates and COVID-19 data.
