The coronavirus disease (COVID-19) epidemic represents a major therapeutic challenge. The highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) and the long duration of the disease have led to a massive influx of patients admitted in health services and intensive care units.
According to current knowledge, there are no treatments that prevent the spread of the infection, especially in exposed populations, or the disease progression to a severe form.
Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR).
Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection.
However, the epidemic is progressing throughout French territory and new variants (in particular the "English B1. 1.7 variant of SARS-COV-2") much more contagious run a risk of accelerating the epidemic in the population. The anti-SARS-COV-2 vaccines recently launched (or being evaluated) represent great hope in this health crisis, but trials were only able to show their effectiveness on symptomatic forms of SARS-COV-2 infection. On the one hand, the vaccination compaign for the entire population requires many months,which leaves many unprotected subjects waiting. In addition, there is currently no evidence of a protective role of vaccines against asymptomatic forms of COVID-19 and therefore on SARS-COV-2 transmission. Finally, the nicotine patches may protect people in hight-risk areas/periods until they are vaccinated (if they accept it and are eligible for it) and in the post-vaccination weeks necessary for the effectiveness of the vaccine,which reinforces the importance of evaluating this alternative prevention strategy, in the context of the arrival of vaccines

- SARS-COV2 seroconversion between W0 and W19 after randomization [ Time Frame: Between week 0 and week 19 ]This is the proportion of subjects with at least one positive serology between W2 and W19.

- Proportion of documented symptomatic COVID-19 infection [ Time Frame: Week 8, Week16 ]
- SARS-COV2 seroconversion [ Time Frame: Week 16 ]This is the proportion of patients with at least one positive serology between W2 and W16.
- Asymptomatic COVID-19 infection proportion at week 14 [ Time Frame: Week 14 ]Asymptomatic COVID-19 infection is defined as SARS-CoV2 seroconversion at Week 19 without symptoms suggestive of COVID until the end of Week 16 to take in account of the two weeks of incubation period
- Proportion of severe COVID-19 infection [ Time Frame: Week 8, Week16 ]documented infection (positive SARS-CoV2 PCR test and / or suggestive chest CT scan and / or seroconversion) whose first symptoms appeared before W8 and W16 respectively, and requiring hospitalization or home oxygen therapy, or having resulted in death
