Immunization | Community Health

Immunization is the process by which the immune system becomes fortified against infectious agents, enabling the body to protect itself through active or passive means. This process involves the improvement of key immune system elements, including T cells, B cells, and antibodies, as seen in the work of scientists like Edward Jenner and Louis Pasteur. The development of vaccines by companies like Pfizer and Moderna has revolutionized the field of immunization, with online platforms like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) providing critical information on immunization practices.
