Mark Kaplan, chair of the department of microbiology and immunology and the Nicole Brown professor of immunology at the IU School of Medicine, is available to discuss the causes of and treatments for summer allergies. According to the U.S. Centers for Disease Control, one in four American adults suffers from seasonal allergies. About 19% of children are also affected. Kaplan has studied the effects of allergies for more than 20 years. His research areas include how T cells contribute to allergic inflammation. 

John Christenson, a member of the IU School of Medicine's Ryan White Center for Pediatric Infectious Disease and Global Health, can speak to childhood vaccination trends and the health implications of immunizations. Vaccination rates for young children have dropped in recent years, according to U.S. Centers for Disease Control and Prevention data. This increases the possibility of disease outbreak and complications in unvaccinated children. Christenson holds board certification in pediatric infectious diseases and serves as associate medical director for pediatric infection prevention at Riley Hospital for Children.
