Vaccination

Advantages

vaccines have helped to control lots of communicable diseases that were once common in the UK ( e.g. measles, polio, rubella and smallpox)
big outbreaks of disease - epidemics - can be prevented if a large percentage of the population is vaccinated so that way even the people who aren't vaccinated are unlikely to catch the disease as there are fewer people to pass it on.

Disadvantages

don't always work - sometimes they don't give you immunity
can have a bad reaction

Evaluation

Deciding whether to have a vaccination means balancing risks - the risk of catching the disease if you don't have a vaccine, against the risk of having a bad reaction if you do. As always, you need to look at evidence.
