The seasonal influenza immunisation programme in England aims to protect those who are most at risk of serious illness or death following influenza infection. Here we look at England’s flu vaccine uptake for people aged 65 years and over, as well as how the UK compares internationally.
For most people, flu is an unpleasant illness, but it is not serious. However, certain people are more likely to develop serious complications of flu, such as bronchitis and pneumonia. Influenza immunisation has been recommended in the UK since the late 1960s, with the aim of protecting clinically at-risk groups who are at a higher risk of influenza-associated morbidity and mortality. In 2000, the policy was extended to include all people aged 65 years and over, and in 2010 pregnancy was added as a clinical risk category. In 2013 to 2014, the childhood programme was first implemented to target children from the ages of two to nine years. This was extended in 2018 to 2019 to all those aged 10 years old.
The ambition for flu vaccine coverage is to reach or exceed 75% uptake for people aged 65 years and over as recommended by the World Health Organisation (WHO). In England, flu vaccine uptake in people aged 65 years and over has fluctuated over time between 71% and 75%. The WHO target was last met in the winter of 2005-06, when flu vaccine uptake reached 75.3%. Notably, there was a drop in flu vaccine uptake to 70.5% in 2016-17. Seasonal data collection runs from September to February, and so far in 2019-20 (between 1 September 2019 and 31 December 2019), uptake has reached 70.6%.
Between 2007 and 2017, the UK had some of the highest levels of flu vaccination coverage among those aged 65 and over, compared to other OECD countries. In 2017, 72.6% of registered patients aged 65 and over were immunised. The Netherlands and the UK consistently have the highest levels of flu vaccine coverage, while Finland, Denmark and Germany generally have the lowest levels of coverage.
About this data
England time series:
It is important to note that influenza vaccine uptake data is only a snapshot of the GP registered patients vaccinated at the time of data extraction. Data captured at the time of data extraction will exclude, for example, updates to patient records on vaccination status, newly-registered patients or changes in clinical risk status. For example, patients who are vaccinated, but have not had their electronic patient record updated by the time of data extraction, will be included within the denominator, but will not be included in the count of the number vaccinated. For more information, please see Public Health England's seasonal influenza vaccine uptake in GP patients: winter season 2018 to 2019 report.
Influenza vaccination rates refer to the number of people aged 65 and over who have received an annual influenza vaccination, divided by the total number of people over 65 years of age. In some countries, the data are for people over 60 years of age. The main limitation in terms of data comparability arises from the use of different data sources, whether survey or programme, which are susceptible to different types of errors and biases. For example, data from population surveys may reflect some variation due to recall errors and irregularity of administration. The definition and comparability information are taken directly from the OECD report Health at a Glance 2017.
