Vaccines have literally transformed the landscape of medicine over the course of the 20th century. Before vaccines, parents in the United States could expect that every year:
However, the disappearance of many childhood diseases has led some parents to question whether vaccines are still necessary. Further, a growing number of parents are concerned that vaccines may actually cause other diseases. Although unfounded, these concerns have caused some parents to delay vaccines or withhold them altogether from their children.
The Center has also established the Parents PACK program to develop a dialogue with parents, provide frequent vaccine information, and establish a place for parents to get up-to-date information and answers to questions about vaccines.
The Center offers the Vaccine Update program for healthcare professionals. The program was designed to make it easier for healthcare providers to stay up-to-date on vaccine news, research and developments. The program includes free webinars, monthly e-newsletters and mailings containing sample materials and announcements when new or revised information is available.
*Members of the public interested in materials offered through the Vaccine Update program can view the materials directly through the Vaccine Update website.
