Subunit Vaccines

Subunit vaccines are designed to deliver antigens (such as proteins or carbohydrates) of a particular pathogen to stimulate the body's immune system to create antibodies which can later protect against the pathogen. By using only the essential parts of the pathogen, the risk of infection or an unwanted reaction is minimized. Subunit vaccines are very safe and effective, and are commonly used for many diseases, such as hepatitis B, tetanus, pertussis and HPV. They are also considered cost-effective due to their ability to be manufactured in large quantities and to be stored for long periods of time.
