My friend's DC who is 17 yrs and 5 months has just had the 2nd jab. Normally you only qualify for the 2nd jab at 17years 9 months. The only exception is if you fall into any of a small number of risk categories, which my friend's DC doesn't.
Has anyone else's 16 and 17yo DCs had the second jab when they do not meet the official criteria?
