Yes, egg allergy is a big no-no for the flu shot. Don't worry about it - my doc laughs whenever I ask about most vaccinations, as people here tend to be rather obsessed with them. Unless you baby is in a high-risk situation (at a day care with 20 other unvaccinated kiddies) then really there shouldn't be any need for it. Better to keep kids well rested and well fed, so their immune systems can cope independently.
