Vaccine uptake refers to the proportion of a population that receives a particular vaccine. This area of research focuses on understanding the factors that influence individuals' decisions to get vaccinated, as well as strategies to increase vaccine uptake rates. Research in this area often examines attitudes and beliefs towards vaccines, access to vaccines, communication methods, and the impact of healthcare policies and guidelines on vaccine uptake. The ultimate goal of vaccine uptake research is to increase vaccination coverage and ultimately protect individuals and communities from vaccine-preventable diseases.
