Why Vaccines are Important for Public Health



Vaccines are one of the most important tools in public health, playing a key role in preventing the spread of disease and protecting individuals from serious illnesses. Vaccines work by introducing a weakened form of a virus or bacteria into the body, which triggers an immune response. This helps the body to build up immunity to that particular virus or bacteria, so that if it is encountered again, it can be quickly and effectively dealt with.

Vaccines have been used since 1796 when Edward Jenner developed the smallpox vaccine – one of the first vaccines ever created. Since then, many more vaccines have been developed for a wide range of diseases such as polio, measles and rubella.

The widespread use of vaccines has had a major impact on public health over the past century. For instance, diseases like smallpox which were once common have now been eradicated due to effective vaccination campaigns. In addition, other diseases such as polio and measles have seen dramatic declines in incidence thanks to vaccines being available to large populations worldwide.

In addition to preventing disease outbreaks on a global scale, vaccines also protect individuals from serious illnesses that can cause long-term disability or even death. Vaccines provide immunity against some of the most dangerous infectious diseases known including diphtheria, tetanus and whooping cough (pertussis). By getting vaccinated against these illnesses you are not only protecting yourself but also those around you as it reduces your risk of spreading these potentially deadly infections onto others who may not be vaccinated or may not be able to get vaccinated due to age or health reasons.

It is therefore clear why vaccines are so important for public health – they help prevent outbreaks on a global scale while also providing protection at an individual level against serious illnesses which can cause long-term disability or even death if contracted without vaccination protection beforehand. Therefore it is essential that everyone takes advantage of available vaccinations in order to protect themselves and those around them from potentially deadly infections and disease outbreaks worldwide
