Vaccinations

JoVE 10903

Vaccination is the administration of antigenic material from pathogens to confer immunity against a specific microorganism. Vaccination primes the immune system to recognize and mount an immune response faster and more effectively if the real pathogen is encountered. Vaccinations are one of the most efficient ways to protect both individual humans and the general public from disease. A growing anti-vaccination skepticism risks the successes of vaccination programs that helped reduce and, in some instances, eradicate fatal diseases. Vaccines can be administered via oral and intranasal routes, as well as by injection into the muscle (intramuscular), the fat layer under the skin (subcutaneous), or the skin (intradermal). Vaccines contain antigens derived from a specific pathogen. Those containing “dead” antigens, which are intact but unable to replicate, are referred to as inactive vaccines. By contrast, subunit vaccines contain only parts of the pathogen. Some vaccines contain the live pathogen in a weakened (attenuated) form. An attenuated pathogen stimulates the immune system without causing severe disease. Vaccines often contain adjuvants, chemicals that enhance the immune response against the pathogen. When a vaccine is administered, antigen-presenting immune cells (APCs), such as dendritic cells or macrophages, engulf the antigen from the v
