Participants' families will be given diary cards to record local and systemic reactions to the vaccines administered, as well as recording daily temperatures for the 7 days after receipt of the vaccines. They will be telephoned 5-7 days after each vaccination to determine if there have been any SAEs since vaccination and to remind them to mail their completed diary cards to the HPA. Participants' families will also receive a memory card on which to record any visits to a doctor or emergency department from the 8th day after vaccine administration to the next study visit and any adverse events recorded in the diary card that are ongoing after day 7.
