During the annual influenza vaccination campaign of 2021, more people were vaccinated compared to 2020. The vaccine coverage in the general population increased from 20.8% in 2020 to 22.9% in 2021. Among persons with an increased risk for complications due to influenza, because of age or a medical condition, vaccine coverage increased from 54.0% to 58.3%.

A possible explanation for the increase in influenza vaccine coverage could be that people were more aware of the importance of influenza vaccination, e.g. because the importance of vaccination against influenza was emphasized during the COVID-19 pandemic. Interestingly, since the COVID-19 pandemic (2020 and 2021) more people started flu vaccination than before. These are people who also received an invitation for vaccination in earlier years, but were not vaccinated then.

The highest vaccine coverage (77.5%) was observed among persons of 65 years or older who also had a medical indication for vaccination. Vaccine coverage was lower in persons under 60 years of age with a medical indication for vaccination (27.0%).
