A brief history of vaccination
Summary
TLDRAdvances in sanitation and healthcare have significantly reduced child mortality, with vaccines playing a crucial role. Diseases like smallpox and polio have been eradicated or drastically reduced through global immunization campaigns. The 21st century sees a life-course approach to vaccination, with vaccines for all age groups. Maintaining high immunization rates is vital as it prevents disease resurgence and reduces healthcare costs. The Global Vaccine Action Plan estimates significant savings through vaccination, and new vaccines for HIV, malaria, tuberculosis, and Ebola are in development, promising a future with more vaccine-preventable diseases.
