Michigan's health department is urging residents to vaccinate their infants on time amid concerns over rising numbers of measles and whooping cough cases.
State officials say the current National Infant Immunization Week is a good time to remind parents that immunizations help protect against 14 serious and potentially deadly diseases before a child's second birthday.
Michigan recorded five measles cases last year, the most since 1999. Measles can still come into the U.S. by unvaccinated people who travel elsewhere where it can be commonplace.
Nearly 1,000 cases of pertussis, or whooping cough, were reported in Michigan in 2013.
Dr. Matthew Davis with the state Community Health Department says the recommended vaccination schedule is designed to provide protection early in life, when babies are most vulnerable.
