Can Meningococcal vaccine of 1ml lead to an over-dosage in a teenager?
Patient: My son is 14 and half year old and I m not sure about his vaccine meningococcal. Can we give now, if it is extra dose - any harm?. I also want to go for HAV but doctor advised 1ml dose where I checked on site the recommended dose up to 18yrs is 0.5ml? Pl advice both my queries. Doctor: Hi, I understand your concern. Meningococcal vaccine is administered to children of 11 to 12 year old. A booster dose is recommended at the age 16 year old. Your son is 14 year old. Although you do not remember if administered the first dose, I advise to wait until he gets 16 year old to get the booster. Another booster is recommended in youngsters of 16 to 23 year old. Hope this answers your query.
