Vaccines prevent between 2.5 and 4 million deaths every year.
The average human gut is home to perhaps 500 to 1,000 different species of bacteria.
According to the National Institute of Environmental Health Sciences, lung disease is the third leading killer in the United States, responsible for one in seven deaths. It is the leading cause of death among infants under the age of one year.
Vaccines cause herd immunity. If the majority of people in a community have been vaccinated against a disease, an unvaccinated person is less likely to get the disease since others are less likely to become sick from it and spread the disease.
More than 30% of American adults, and about 12% of children utilize health care approaches that were developed outside of conventional medicine.
