At my local medical centre (we are not registered there as I chose to go to a Dr's a little further away) a boy was given the MMR without his mums's consent. She had taken him for DTP and checked with the nurse when she signed the consent form that.
The boy had already received the single vaccines last year privately and had previously had a reaction to the meningitus jab which landed him in hospital.
Its terrifying to think what trust we put in these health professionals.
