COVID-19 Vaccines: Development, Distribution and Mandates

Vaccines protect people from disease by preparing the body to respond to an infection. Vaccinations are a key part of individual and community health, but vaccine development remains complex and costly. Innovative technologies and approaches may enhance the nation's ability to respond to infectious diseases. For example, reverse vaccinology and next-generation platforms-combined with existing research-helped researchers develop some COVID-19 vaccines more quickly and effectively.
