3. Diseases which are preventable by vaccination still exist
In fact, cases of disease such as measles – which are preventable – still occur today in the UK. Global measles deaths have decreased by 84% from an estimated 550 000 deaths in 2000, to 89 780 in 2016, thanks to immunization programmes.

Bacteria and viruses capable of causing illness and death can be easily transferred to those who haven’t been vaccinated against them.
With global travel ever more popular, diseases are just as able to travel as people.
