Mass vaccination against flu has started in Belarus. It is planned that about 40% of the population will receive vaccinations. The process begins earlier than usual: this is due to the fact that this season 2 viruses will circulate at once – flu and coronavirus. First of all, vaccinations should be provided to persons with chronic diseases, children under 3 years old, the elderly and pregnant women, health workers and law enforcement officers. Doctors note that last year vaccination prevented more than 140 thousand cases of flu, including 17 thousand in a complicated form.
