Vaccine reactions common

A study of children taken to a paediatric emergency unit in France found that antibiotics and vaccines were the most likely causes of any drug reactions. The French researchers found that over three quarters of all suspected adverse reactions were caused by either antibiotics or vaccines. One child was brought in with a life-threatening coma having received hepatitis B and MMR vaccines. It is perhaps no coincidence that these two vaccines are amongst the most 'reactogenic' - that is likely to cause adverse reactions - of all the commonly given vaccines.
