Vaccines credited with eradicating diseases such as diphtheria, polio and measles in the United States sometimes still get a bad rap.
Some people believe that they aren't effective or may cause dangerous side effects. Some say they are no longer needed because most vaccine-preventable diseases are no longer a major threat. Some think vaccinations are just for children.
According to the December issue of Mayo Clinic Women's HealthSource, those beliefs are largely based on myth.
It's true that vaccines aren't 100 percent effective. But most routine childhood vaccinations reduce the likelihood of illness by 85 percent or more. During an outbreak, some who have been vaccinated still may develop the illness. However, they usually have a milder case.
The most common side effects from vaccines are minor and temporary such
as a mild fever or soreness at the injection site.
And, vaccines are still necessary. Diseases now rare in the United States are still common elsewhere, and they are just a plane ride away. Vaccines aren't just for kids, either. Talk with your doctor about vaccinations that might benefit your health.
Adult vaccinations include:
Influenza: This vaccination is recommended annually for adults age 50 and older, adults with chronic illnesses or weakened immune systems, health care workers and those in contact with young children.
