Human noroviruses (HuNoVs) have become the leading cause of acute nonbacterial gastroenteritis in countries where rotavirus vaccination has been successfully implemented. Overall, HuNoVs have been identified in ~18% of reported acute gastroenteritis cases worldwide. In the United States, HuNoVs result…
This chapter provides an overview of the challenges and advances in vaccine development for chronic and noncommunicable diseases. Because of space limitations it is not possible to provide an exhaustive representation of the field; consequently, we address a few major…

## Meningococcal disease was first described in Geneva, Switzerland in 1805. Different capsular groups of meningococci were first recognized serologically in 1909, and serogroup B was defined based on the immunological difference in capsular polysaccharide structure in the 1940s. Capsular…
## Meningococcal disease, caused by the bacterium Neisseria meningitidis , is a deadly illness that can progress rapidly. The case fatality rate, which was 70%–85% before the advent of antibiotics, is now 10%–15%, and many survivors have long term sequelae…
