One of the most important public health measures of modern times, immunizations have saved countless lives. Sometimes called vaccinations, jabs, or shots, they help protect people from dangerous and contagious diseases by boosting their immune systems. Immunizations come in various forms, including oral drops, nasal sprays, and injections. They are available for a wide range of illnesses, from influenza and pneumonia to measles, mumps, and rubella. Regardless of the name used, the goal of all immunizations is the same - to help people stay healthy and avoid sickness and suffering. So whether you refer to them as vaccines, inoculations, or preventatives, it pays to encourage everyone to get immunized.
