Measles and mumps outbreaks have occurred in Canada, Europe, and the Middle East. Polio has shown a fierce stubbornness, resurfacing in Somalia after six years. The disease has reached Israel, which is vaccinating one million children, from Pakistan, one of three countries, along with Nigeria and Afghanistan, where it remains endemic.
Those countries may be far away, but distance no longer provides the protection it once did. A measles outbreak in Brooklyn earlier this year, brought back by an overseas traveler, is a stark reminder that an outbreak — or epidemic — can be just one plane ride away.
Too many people are losing sight of the importance of vaccines. More states are granting medical and philosophical exemptions from childhood vaccinations, and the medical-conspiracy theorists are still at it; despite mountains of scientific evidence on the safety of vaccines, scare tactics can still work with some people.
The irony and frustration of the current resurgence of these diseases is that as more diseases become drug-resistant, as new ones like MERS emerge, we continue to fight the old ones we can easily prevent.
Physicians must recognize the rights of parents to make what they believe are proper decisions about immunizations for their children, even if the physician and the scientific evidence do not support that decision. However, physicians, parents, and patients of all ages must recognize that immunization is a public health priority as well as a personal health issue.
Vaccines have an enviable safety record, they prevent diseases that once claimed millions of lives (and in some countries, still do), and high vaccination rates provide a collective, public health advantage, as even those who are not immunized benefit from “herd immunity” because so many others do get vaccinated.
Vaccines are considered one of medicine’s greatest advances and should be an indispensable part of primary care. With them, we can easily, inexpensively prevent suffering, illness, and death. Without them, our most vulnerable individuals are needlessly put at risk of disease, with the potential for future and lifelong complications. The choice should be clear.
