A phase IV study to evaluate the primary and booster immune responses of UK infants receiving a licensed 6-in-1 DTaP/IPV/Hib/HBV vaccine (Infanrix-Hexa) with a 13valent pneumococcal conjugate vaccine and incorporating a randomisation study of a single dose of 3 different meningococcal group C conjugate vaccines at 3 months of age

Background and study aims
Infants in the UK are routinely immunised against diphtheria, tetanus, pertussis, polio and Haemophilus influenzae serotype b (Hib) using a 5in1 combination vaccine (Pediacel™) given at 2, 3 and 4 months of age. These infants also receive vaccines that protect against meningococcal group C (MenC) and pneumococcal disease as part of this schedule. Hepatitis B is an infection of the liver caused by the Hepatitis B virus (HBV). Chronic (long-term) infection with HBV increases the risk of liver failure, cirrhosis and cancer. The UK currently has a selective HBV immunisation strategy targeting only those considered at high risk of HBV infection. There is an opportunity to introduce a licensed 6in1 vaccine (InfanrixHexa™) to replace the current 5in1 vaccine (Pediacel™) in the infant schedule. This vaccine should protect infants against all the same infections but in addition will protect against hepatitis B. The development of combination vaccines is complex and there is the potential for interactions between the different components of a combination vaccine and also between different vaccines given at the same visit. The aim of this study is to ensure that giving InfanrixHexa™ with MenC and the pneumococcal vaccine as part of UK infant schedule will offer adequate protection against the infections it is designed to protect. In addition, although infants in the UK currently receive two doses of MenC vaccine at 3 and 4 months of age, recent studies have shown that a single MenC dose in infancy provides adequate protection and, therefore, the UK infant schedule will soon move to a single MenC vaccine dose given at 3 months of age. As a result, we aim to randomly allocate infants to receive one of three licensed MenC vaccines at 3 months of age.
Who can participate?
Infants born at term (at least 37 weeks gestation) and aged less than 10 weeks who have not yet received their primary immunisations.
What does the study involve?
Infants are randomly allocated to receive one of three MenC or MenC-containing vaccines at 3 months of age: NeisVacC™, Menjugate™ or Menitorix™. Hib and MenC antibody levels are measured one month later, before routine booster vaccination at 12 months of age.

Study objectives | Infants in the UK are routinely immunised against diphtheria, tetanus, pertussis, polio and Haemophilus influenzae serotype b (Hib) using a 5in1 combination vaccine (Pediacel™) given at 2, 3 and 4 months of age. These infants also receive vaccines that protect against meningococcal group C (MenC) and pneumococcal disease as part of this primary schedule. Hepatitis B is an infection of the liver caused by the Hepatitis B virus (HBV). Chronic infection with HBV causes significant morbidity and mortality as there is an increased long term risk of liver failure, cirrhosis and cancer. The UK currently has a selective HBV immunisation strategy targeting only those considered at high risk of HBV infection. There is an opportunity to introduce a licensed 6in1 vaccine (InfanrixHexa™) to replace the current 5in1 vaccine (Pediacel™) in the infant schedule. This vaccine should protect infants against all the same infections but in addition will protect against hepatitis B. The development of combination vaccines is complex and there is the potential for interactions between the different components of a combination vaccine and also between different vaccines given at the same visit. The proposed study aims to ensure that giving InfanrixHexa™ with MenC and the pneumococcal vaccine as part of UK infant schedule will offer adequate protection against the infections it is designed to protect. In addition, although infants in the UK currently receive 2 doses of MenC vaccine at 3 and 4 months of age, recent studies have shown that a single MenC dose in infancy provides adequate protection and, therefore, the UK infant schedule will soon move to a single MenC vaccine dose given at 3 months of age. As a result, we aim to randomise infants to receive one of 3 licensed MenC vaccines at 3 months of age. |

Intervention | Babies taking part in this study will be randomly allocated to receive one of 3 MenC or MenC containing vaccines at 3 months of age: NeisVacC™, Menjugate™ or Menitorix™. Recent clinical trials have shown that one dose of NeisVac™ or Menjugate™ given to babies at 3 months of age provides similar protection against MenC disease as two doses. |
