We have been offered flu jabs for DDs age 2 and 4. Neither have any respiratory/asthma type issues, and generally very good health (have been very fortunate in that to date they have rarely gotten ill and never seriously, not been on antibiotics etc).
AIBU not to vaccinate them as they don't appear to be high risk? My understanding is that flu is most dangerous to people with weak immune and weak respiratory problems. If they do get it, they'll be unwell but ok, and develop some resistance/ resilience etc.
However, I'm now wavering as someone said they heard on the radio that it recommended small children DO get immunised as it will reduce the spread of flu and therefore be better for others who are more compromised. I hadn't considered that previously, not sure what to do now.
