Vaccination programs are organized efforts to provide vaccines to protect people from infectious diseases. These programs aim to immunize large groups of individuals, especially children, against illnesses like measles, polio, and influenza. By receiving vaccines, people develop immunity, which helps prevent the spread of these diseases in communities. Governments and health organizations often run vaccination programs to ensure that everyone has access to necessary vaccines. They may offer free or low-cost vaccinations at clinics, schools, and community events. This helps to keep populations healthy and reduces the risk of outbreaks, ultimately saving lives and healthcare costs.
