For just a few dollars a dose, vaccines save lives and help reduce poverty. Unlike medical treatment, they provide a lifetime of protection from deadly and debilitating disease. They are safe and effective. They cut healthcare and treatment costs, reduce the number of hospital visits, and ensure healthier children, families and communities.
Leadership is about vision and responsibility, not power.
New vaccines are being developed all the time, which could save many more lives and dramatically improve people's health. And this goes beyond the traditional burden of childhood infectious diseases.
Now, when you get a viral infection, what normally happens is it takes days or weeks for your body to fight back at full strength, and that might be too late. When you're pre-immunized, what happens is you have forces in your body pre-trained to recognize and defeat specific foes. So that's really how vaccines work.
Measles is probably the best argument for why there needs to be global health, and why we have to think about it as a global public good. Because in a sense, measles is the canary in the coal mine for immunization. It is, you know, highly transmissible. The vaccine costs 15 cents, so it's not - you know, shouldn't be an issue in terms of cost.
