Risks of an adverse event following influenza vaccination are far less common than complications related to influenza itself, and the adverse events are generally localised and mild.
Poliovirus is highly contagious and infected individuals shed virus in the faeces and from oral secretions, thus the mode of transmission is person-to-person, both via the faecal-oral and the oral-oral routes.
Seasonal influenza is a vaccine-preventable disease and annual influenza vaccination is the most effective way to prevent influenza. ECDC continues to emphasise that all Europeans who are recommended to have the influenza vaccine should get vaccinated.
