DS has just had a serious episode of wheezing, resulting in blue lights, nebuliser twice to stabilise 80% oxygen and a night in A&E. The school flu vaccines are next Friday 6th. He can’t have his vaccine that day as it’s within a fortnight of the wheezing incident but I’m worried about him being exposed to shedding from other children so am inclined to keep him at home for the day. AIBU?
