Vaccination Introduction

Immunization is saving millions of lives every year across the world. Vaccines play a key role in increasing immunity and reducing infection risks by working with the human body’s natural defenses. According to WHO, we now have vaccines to prevent more than 20 life-threatening diseases, helping people of all ages live longer and healthier lives. It is estimated that vaccination prevents about 3.5 to 5 million deaths every year.

Recent COVID pandemic also highlighted the critical role that vaccines play in prevention and control of infectious disease outbreaks. Vaccines have become an indispensable tool for improving the wellness of humankind. Despite the progress, there is still work to be done. Vaccination is still a privilege and not a basic right for a vast majority of the population.

We aim to explore the global trends in children vaccination, understand the challenges in achieving higher vaccination rates and identify insights that can help governments and NGOs in improving the effectiveness of future vaccination drives.

Vaccine Preventable Diseases

A vaccine-preventable disease (VPD) is an infectious disease for which an effective preventive vaccine exists. If a person acquires a vaccine-preventable disease and dies from it, the death is considered a vaccine-preventable death. The bar chart below shows the most prevalent diseases and how their death rates have changed in the last four decades.

Vaccines Covered

Below listed are the children vaccines that provide protection against these diseases. We have limited the scope of this project to just the vaccines given to children as there is more uniformity and focus on them around the world, resulting in better data.
