you better ask more from your doctor if you planned to give your child the injection, because, some discomfort caused after the injection
not very serious but full of discomfort, from my experience, in last year (I am pregnant so without receiving), my colleague received as well as her children, claimed very discomfort with cough, so this year she would not receive even we had not yet clarified whether 'same' or not
just for sharing, but I would receive as I'm working in hospital
