Early results from the 2013 to 2014 child flu vaccine pilot programme suggest a positive impact on levels of flu in the United Kingdom.
In 2012, the Joint Committee on Vaccination and Immunisation advised extending the national flu immunisation programme to all children from the age of two to less than 17 years.
In addition to protecting healthy children from flu, the extension aimed to reduce the spread of flu and protect younger siblings, grandparents and those who are at increased risk of becoming seriously ill from flu.
As a first step in the extension of the programme, all children aged two and three years were offered flu vaccination last year, while children aged between four and 11-years-old were vaccinated in seven pilot areas.
Pilots took place in Bury, Cumbria, Gateshead, Leicester, East Leicestershire and Rutland, and the London Boroughs of Havering and Newham and South East Essex. A total of 104,792 primary age children received at least one dose of a nasal spray flu vaccine, or a needle vaccine for the small number of children unable to receive the nasal spray vaccine. This represents an overall uptake of 52.5% in the target group.
Despite the low flu activity in 2013 to 2014, early results, although statistically non-significant, suggest a positive impact.
Results were obtained from a range of surveillance indicators including GP consultations for influenza-like illness, swab positivity in primary care, laboratory confirmed hospitalisations and percentage of respiratory emergency department attendances.
The influenza rate in primary care in pilot areas was 8.5% compared to 16.2% in non-pilot areas. The proportion of emergency department respiratory attendances was 5.5% in pilot compared to 8.7% in non-pilot areas.
From September 2014 vaccination against flu will be offered to all children aged two to four years of age. The geographical pilots for primary school children established in 2013 to 2014 will continue and a number of additional pilots for secondary school age children in years 7 and 8 (ages 11 to 12) will also begin in some areas.
Dr. Richard Pebody, study author and flu expert at PHE, said: “These early results of the uptake and impact of the first year of the childhood flu vaccine programme are encouraging and the uptake levels already achieved in primary school age children in the pilot areas are positive.
“Despite the season being of relatively low intensity, these early findings already suggest a likely impact of vaccinating school-age children on levels of circulating flu, which is encouraging for the on-going roll-out.”
Dr Paul Cosford, Director for Health Protection and Medical Director at PHE, said: This is an important addition to the national programme and is being carefully planned. The pilots are helping us to understand the best way to implement the programme nationally, ensuring that we can set up a successful and sustainable programme, vaccinating children and young people to protect them and the wider population.”
