European Commission/ EUR-Lex: Council Recommendation on Raising seasonal vaccination coverage among risk groups and healthcare workers (22 December 2009)
Council Recommendation on Raising seasonal vaccination coverage among risk groups and healthcare workers (22 December 2009)
Technical report In Brief: Narcolepsy in association with pandemic influenza vaccination
This report summarises the results from two epidemiological studies to investigate a possible association between an unexpected increase in narcolepsy cases following the use of the influenza A(H1N1)pdm09 vaccines. The studies were conducted by the Vaccine Adverse Event Surveillance and Communication (VAESCO) Consortium under the auspices of ECDC and undertaken in Denmark, Finland, France, Italy, the Netherlands, Norway, Sweden and the United Kingdom. This Technical Report In Brief accompanies the full Report ‘Narcolepsy in association with pandemic influenza vaccination- A multi-country European epidemiological investigation’.
Seasonal influenza vaccines
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. Vaccination is especially important for people at higher risk of serious influenza complications: Individuals with specific chronic medical conditions, pregnant women, and children aged 6-59 months, the elderly and healthcare workers.
WHO recommendations for influenza virus vaccine composition for the 2018 southern hemisphere influenza season
The World Health Organization (WHO) has recommended the composition of the trivalent influenza vaccine for the southern hemisphere winter 2018 influenza season in a report published 28 September 2017.
European Commission: Influenza
Vaccination policy is a competence of national authorities however, the European Commission supports EU countries to coordinate their policies and programmes. To support EU countries in maintaining or increasing rates of vaccination, the EU Commission promotes seasonal flu vaccination to at risk groups.
Yearly updates of influenza vaccines
An update of seasonal influenza vaccines is needed yearly, since influenza viruses constantly evolve. How effective the seasonal influenza vaccine is each season depends on the match between the selected vaccine viruses and those found circulating, and will therefore vary from year to year.
Immunity following influenza disease and administration of influenza vaccines
For infants the first encounter with influenza viruses commonly occurs in their first or second winter season. Subsequently, each individual acquires a number of influenza infections throughout life. It is expected that up to ~15% of a European population in a temperate climate is infected with influenza in any winter season with higher percentages in children and lower in older people.
Low uptake of seasonal influenza vaccination in Europe may jeopardise capacity to protect people in next pandemic
Influenza vaccination coverage among high-risk groups has dropped in the European Region over the last seven years, and half the countries report a decrease in the number of vaccine doses available.
