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.
Despite good access to effective antibiotics, Streptococcus pneumoniae (pneumococci) is still a major cause of disease and death in both developing and developed countries. Pneumococci are the main cause of bacterial respiratory tract infections, such as pneumonia, middle ear infection, and sinusitis, in all age groups.
Mumps is a viral infection first described by Hippocrates that in its classical form causes acute parotitis and, less frequently, orchitis, meningitis and pneumonia.
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.
