Types of seasonal influenza vaccineArchived

Data set

A detailed overview of available seasonal influenza vaccines in the EU/EEA will not be available for the 2020/21 vaccination programmes, due to limited ECDC resources following the COVID-19 response.


Injected trivalent inactivated influenza vaccines are most commonly used throughout the world. Influenza antigen preparation varies between manufacturers. The inactivated influenza vaccines available in the EU/EEA may contain either split virion influenza virus products or subunit influenza products. Adjuvanted inactivated subunit influenza vaccines for older people are available in some EU/EEA Member States.

Injected quadrivalent inactivated influenza vaccines, available from the 2014/2015 season in some EU/EEA countries, are expected to replace the trivalent vaccines over time. Although available in the private market in some European countries, vaccine authorisation, vaccine availability, observed vaccine effectiveness and the cost may influence the speed of this replacement.

In 2011, a live attenuated influenza vaccine (LAIV) for intranasal use was approved in the EU/EEA for children and adolescents (2-17 years of age). All live attenuated influenza vaccines currently available are quadrivalent combination vaccines containing two influenza A strains (H1N1 and H3N2 subtypes) and two influenza B strains (Victoria and Yamagata lineages) as per WHO recommendations.

The universal paediatric programmes organised in Finland and the United Kingdom offer quadrivalent LAIV to either young children 2-3 or 2-11 years of age, respectively.

Since seasonal influenza vaccines are usually recommended for several vulnerable populations who are poorer immune responders due to age or disease, several attempts to improve the vaccines have been explored over the last 10-15 years such as: increasing the antigen dose administered, intradermal administration to activate other arms of the immune system, and adding immunostimulating compounds such as adjuvants (See reference 1-4).

Products utilising these new techniques are now authorised and available in some EU/EEA countries. See table below. For human influenza vaccines, MF59 (squalene) and AS03 (squalene and α-tocopherol) have been approved as adjuvants by regulatory agencies in the EU, Canada and the United States. Data from several observational studies indicating improved performance and reductions in hospitalisations in older adults against influenza disease and hospitalisations have been included in the label for the adjuvanted trivalent influenza vaccine.

Most influenza vaccines, both inactivated and live attenuated, are based on production of influenza viruses/antigens in fertilised hens' eggs. These vaccines can therefore not be given to egg-allergic individuals developing severe symptoms upon exposure to egg proteins. Hence, a few manufacturers have developed cell-based influenza vaccines which can be given to severely egg-allergic individuals. Use of cell-based products may have an improved match to circulating influenza strains as they avoid egg-adaption issues.
