Our surgery is now inviting all children 6 months to 5 years to have the vaccine. I have provisionally booked my dds in (7 months and 2.8 yrs old) but I do feel like we're part of a massive clinical trial. The nurse couldn't answer any of my questions re. how it's been tested and how safe it really is for this age group. So, have your little ones had it and how was it for them?
