This study is exploring the safety and effectiveness of a meningococcal conjugate vaccine given with routine vaccines to babies and toddlers in the UK. Meningococcal disease is a serious illness caused by bacteria. This research will last for about 11 to 12 months for each participant. Babies aged 56 to 89 days old, born full term (at least 37 weeks) and weighing at least 2.5 kg (5 lbs 8 oz) at birth, are eligible to join.
Participants will need to visit the study site several times during the study. Parents must agree to these visits and follow study procedures. It is important to know that babies who have had certain previous vaccinations, medical conditions, or are participating in another clinical trial cannot join this study.
Key Points:
- Study lasts 11-12 months with multiple visits.
- For babies 56-89 days old, born full term.
