Vaccination is one of most cost effective healthcare interventions, preventing millions of deaths and saving 750,000 children from disability caused by diseases like polio, haemophilus infl uenza type b and meningococcal infection each year.
Since 2006, with the development of new vaccines against HPV (human papillomavirus), vaccines can now prevent development of precancers of the cervix caused by the HPV virus.
Vaccines, contain antigens, which may be live (MMR vaccine), or non live (meningococcal C), that interact with the immune system and often produce an immune response like that produced by a natural infection, but without having the disease or its complications. Many vaccines provide long term protection against disease by producing immunologic memory similar to that which develops after having the natural disease.
Vaccination has led to the complete eradication of smallpox. Thanks to vaccination fewer children were paralysed by polio in 2017 than ever before, with the polio virus now limited to a few areas in Afghanistan, Pakistan and Nigeria.
There are 3 different polio viruses. Polio type 2 was offi cially declared eradicated by vaccination in 2015; type 1 has not been found since 2012. Type 3 is the only remaining strain ‘in the wild’.
