The Impact of Vaccines

Most of developed world take vaccines for granted. Indeed, there is a growing number  of people in wealthy countries, often the most privileged, who outright fear and dislike vaccines. Yet the data are overwhelming: vaccines have not only been pivotal to virtually extinguishing all sorts of previously common diseases (measles, polio, pertussis, etc.), but they have continued to reap dividends for the millions of human who live in the developing world, where public health otherwise remains weak.

As reported in IFLS:

Vaccines are well regarded as one of the most cost-effective health care actions that a country can pursue, and since 2001 the United Nations has been running a program in 73 low and middle-income countries to prevent 10 diseases. It is now expected that when the project is completed in 2020, it will have resulted in averting around 20 million deaths, while at the same time saving a staggering $820 billion.

“Our examination of the broader economic and social value of vaccines illustrates the substantial gains associated with vaccination,” explained Sachiko Ozawa, who led the research, in a statement. “Unlike previous estimates that only examine the averted costs of treatment, our estimates of the broader economic and social value of vaccines reflect the intrinsic value that people place on living longer and healthier lives.”

And these economic benefits, it turns out, are huge. The researchers have calculated that when the vaccination program comes to an end in 2020, it will have saved around $350 billion when it comes to health, but overall this balloons to an astonishing $820 billion across the 73 low and middle-income countries in which Gavi is operating.

This is not only through reduced health care costs as diseases are prevented before they become an issue, but also due to those who are vaccinated being healthier and so working for longer and thus increasing productivity in these nations over their entire lifetimes.

Social and economic benefits aside, the most important results are the human ones: the prevention of over 500 million illnesses, 20 million child deaths, and 9 million cases of long-term disabilities. So much pain and suffering and loss will be unknown — and unfortunately unappreciated — because of such a cheap and relatively easy intervention.
