It is understandable that people may show concern about having a new vaccine which has, of necessity, been developed relatively quickly and the tests completed in such a short period of time, so criticising anyone who may be hesitant to have it is rather unfair.
Understandably, people are often concerned to know how rigorously and extensively vaccines have been tested. This is especially true for new vaccines. This page aims to outline the process involved in developing and licensing a vaccine for use in the UK. The standard for testing and monitoring of vaccines is higher than it is for most other medicines, because they are one of the few medical treatments given to healthy people (mainly healthy children). This means that the level of acceptable risk is much lower than it might be for a cancer treatment, for example. It can take many years for a vaccine to pass through all the stages described below. In the case of the MenB vaccine, for example, it took nearly 20 years from the first idea to the vaccine being licensed for use.
