Filter by:Most adolescents who receive human papillomavirus (HPV) vaccine are vaccinated in pediatric practices, yet missed opportunities (MOs) for HPV vaccination occur often and lead to low HPV vaccination rates. This single arm evaluation (embedded within arm 1 of a 2-arm cluster randomized clinical trial (RCT)) will test the sustainability of improvement made in response to a bundled intervention including HPV vaccine communication, performance feedback and provider prompts to reduce MOs and increase HPV vaccination rates.
The National Vaccine Evaluation Consortium conducts Department of Health funded trials trials to provide information to underpin changes to the national immunisation and vaccination schedule. This study will assess how different schedules of pneumococcal conjugate vaccines work in providing protection to young infants. It is well established that vaccines can behave differently depending on which order they are given and alongside which other immunisations. This has been shown for Hib and MenC vaccines, which are similar in structure to the pneumococcal vaccines that will be studied here. The investigators will measure responses to the pneumococcal vaccines as well as to other routine immunisations, all of which will be provided by our study team. Infants will be recruited by dedicated study staff through primary care and will participate from their first vaccinations at 2 months of age, until the blood sample taken a month after their boosters at a year old, i.e. until 13 months of age. Any child found to have antibody levels below that which indicates protection for Hib, MenC, MenB or pneumococcal in the blood sample taken at 13 months of age will be offered an extra dose of the relevant vaccine(s).
