Vaccines have reduced and, in some cases, eliminated many diseases that killed or severely disabled people just a few generations ago. For example, smallpox vaccination eradicated that disease worldwide. Your children don’t have to get smallpox shots any more because the disease no longer exists. By vaccinating children against rubella (German measles), the risk that pregnant women will pass this virus on to their fetus or newborn has been dramatically decreased, and birth defects associated with that virus no longer are seen in the United States. If we continue vaccinating now, and vaccinating completely, parents in the future may be able to trust that some diseases of today will no longer be around to harm their children in the future.(U.S. Department of Health and Human Services, 2006). Vaccines protect future generations. Vaccinated mothers protect their unborn children from viruses that could potentially cause birth defects, and vaccinated communities can help eradicate diseases for future generations. Before the rubella vaccine was licensed in 1969, a global rubella (German measles) outbreak caused the deaths of 11,000 babies, and birth defects in 20,000 babies between 1963 and 1965 in the United States. Women who were vaccinated as children against rubella have greatly decreased the chance of passing the virus to their unborn or newborn children, eliminating the birth defects, such as heart problems, hearing and vision loss, congenital cataracts, …show more content…
Mercury, specifically thimerosal, is a controversial ingredient that was inserted into vaccines as a preservative. Mercury is a naturally occurring element found in the earth's crust, air, soil, and water. There are two types of mercury to which people may be exposed, methylmercury and ethylmercury. Thimerosal contains ethylmercury, which is cleared from the human body more quickly than methylmercury, and is therefore less likely to cause any harm (“Thimerosal”, 2015). Thimerosal was added to vials of vaccine that contain more than one dose (multi-dose vials) to prevent growth of germs, like bacteria and fungi. Contamination by germs in a vaccine could cause severe local reactions, serious illness or death. In some vaccines, preservatives, including thimerosal, are added during the manufacturing process to prevent germ growth (“Thimerosal”, 2015). Between 1999 and 2001, thimerosal was removed or reduced to trace amounts in all childhood vaccines except for some flu vaccines. This was done as part of a broader national effort to reduce all types of mercury exposure in children before studies were conducted that determined that thimerosal was not harmful (“Vaccines do not cause autism”, 2015). Research does not show any link between thimerosal in vaccines and autism, a neurodevelopmental disorder. Many well conducted studies have concluded that thimerosal in vaccines does not contribute to the development of
