The PCV15/PCV20 Study

Title: Evaluation of higher valency pneumococcal vaccines (PCV15/PCV20) compared to PCV13 given in homologous schedules at 3 months and 12 months (“1+1” schedule) and 2 months, 4 months and 12 months (“2+1” schedule) in infants

You are invited to enrol your 2–month-old baby to take part in a study which will help guide decisions on future changes to the UK National Immunisation Schedule in relation to Streptococcus pneumoniae (pneumococcus) vaccines.

We are looking to recruit healthy babies who are 8-10 weeks of age, born after 37 weeks gestational age and have not yet received their first vaccinations. They will be offered two or three doses of a pneumococcal vaccine along with their routine vaccinations. The study is being co-run with the Women`s and Children's Research unit and taking place at the Bristol Royal Hospital for Children.
