    • "This paper explores whether and to what extent vaccine refusal is protected under the Charter and argues that the elimination of nonmedical exemptions can be justified under Section 1 of the Charter. The issue of mandatory vaccination may take on special urgency in the coming months and years, if and when a vaccine is found for COVID-19."

                    The purpose of the present study was to investigate the incidence and relative risk of infection Covid-virus in soccer players. Data from five leagues was used and compared to data from the normal population in each country. Our results revealed that the relative risk was higher in soccer players in three countries when correcting for the estimated true number of infected people in the populations. We discuss that the reason for the higher incidence in soccer players is caused by the virus entering a group of players that work closely together.
