My boy has had all scheduled vaccinations up to now. no MmR but singles. Now we come to the DTaP/IPV and MMR booster. What I'm wondering is does he really need them? I read on other threads that the MMR singles are considered more effective than the 3 in 1 and the booster is not a booster as such but a repeat of the first dose to pick up the few who did not achieve immunity. Also I've read that too many Tetanus jabs are not necessary or good for little ones. (All this reading on mumsnet). Any thoughts?
