Monitoring vaccine safety
In the UK the Yellow Card Scheme allows doctors, other healthcare professionals, and you to report suspected side effects from any medicine you are taking, including vaccines.
It is run by the Medicines and Healthcare Products Regulatory Agency (MHRA). The MHRA regularly reviews the yellow card reports and if it feels there is a potential problem, will carry out an investigation and, if necessary, take appropriate action.
Most reactions reported through the Yellow Card Scheme have been minor reactions such as rashes, fever, vomiting, and redness and swelling where the injection was given.
There is also a legal requirement for pharmaceutical companies to report serious and suspected adverse events to the MHRA.
