Hi! Couldn't find a single question about injections during the flu in the search! Please tell me, girls, who had this experience — did everything turn out well with the child? They prescribed 7 days of ceftriaxone, they're afraid it will turn into viral pneumonia; right now the child has bronchitis. I'm thinking of starting the injection tonight — any opinions? The family won't allow it, but the GP insists. Thanks in advance
