Immunization, or vaccination, stimulates the immune system by injecting a weakened or destroyed virus. Antibodies, which help the body fight pathogens, are produced. Vaccines prevent disease by creating immunity to a pathogen. Immunization has eliminated dangerous illnesses like smallpox and reduced the prevalence of others like polio and measles, making it a cornerstone of public health. One of the most successful public health campaigns ever, it saved countless lives. Crossroads Rx Pharmacy recognizes the importance of immunization to community health. The pharmacy offers a variety of vaccines to all ages through an immunization program run by trained pharmacists and healthcare professionals. Immunization services at the Ellicott City pharmacy promote health knowledge and illness prevention.
