Greek authorities are urging vulnerable members of the population, such as the elderly and people suffering from chronic illnesses, to get vaccinated against potent strains of the flu expected this winter.
Health experts say that since flu outbreaks usually start in mid-December, it's best to get the flu shot in October or November.
The death toll in Greece from West Nile virus since June this year has risen to 25, according to this week's report by the National Health Organization (EODY).
Up until September 19, authorities had diagnosed a total of 195 cases of the mosquito-borne virus. Of these, 121 developed illnesses affecting the central nervous system such as encephalitis or meningitis.
Fears provoked by the anti-vaccination movement may appear exaggerated if we consider that, worldwide, the vast majority of people believe that vaccines are safe and effective (79 percent and 84 percent, respectively, according to the World Health Organization). Yet a small number of unvaccinated people is enough to threaten the immunity of the population.
