Brief Summary:

Menitorix is a combined Hib conjugate and meningococcal C conjugate vaccine made by GlaxoSmithKline. It is currently licensed and recommended as a booster vaccination for UK children in the second year of life.

It is important that staff who have a potential occupational exposure to infectious disease are afforded protection where possible. The licensure and availability of Menitorix provides the opportunity to vaccinate such staff.

Immune responses that are indicative of protection have been established for both Hib and meningococcal C disease. It is therefore proposed that the immune responses of those laboratory staff taking part be measured as data currently available following Menitorix vaccination is in naïve children and adults. This study will also allow us to provide occupational healthcare to laboratory workers.

Participation in the study would be offered to all those staff considered to be at occupational health risk of Hib or meningococcal C disease at the Manchester HPA site. This will be a single group study in that everyone enrolled will receive a single dose of Menitorix and will have blood collected prior to and 4-6 weeks following vaccination.

Assessment of whether protective levels of antibody have been achieved will be made using the blood sample taken 4-6 weeks after vaccination. Extra dose(s) will be offered to any subjects whose levels are not considered to confer protection as described later in this protocol. Subjects receiving and extra vaccination will be offered and a further blood test 4-6 weeks later to allow antibody levels to be checked again.
