In recent years, some parents have become concerned about the safety of vaccinations. However, leading medical professionals continue to assure parents that vaccines are, in fact, safe. The vaccines go through a very rigorous quality control process that starts with extensive testing in laboratories, followed by human testing. A vaccine must pass the approval of the Food and Drug Administration, or FDA, before it reaches a larger audience, and the entire process can take a number of years.
Once a vaccine has approval, ongoing inspections and quality control measures further help safeguard the vaccine supply. In fact, a manufactured batch of vaccines cannot go out to the public at all until the FDA evaluates it. Additionally, organizations and agencies maintain reporting systems, such as the Vaccine Safety Datalink Project, that track any adverse effects of vaccines once medical professionals administer them. In the vast majority of cases, these effects are not serious and the potentially life-saving benefits outweigh the risks. A doctor can provide additional information on the importance of vaccines and their pros and cons.
