Uses of immunotherapy
Immunotherapy may be used to:
Treat or manage cancer. Immunotherapy may be used with other treatments to help them
work better. Immunotherapy works best to treat early-stage cancers.
Prevent cancer. Cancer vaccines help protect against viruses that can cause some cancers.
One example is the vaccine for human papillomavirus, or HPV, which causes cervical
cancer, as well as other cancers.
Control asthma and allergy symptoms. Immunotherapy shots are often given to people
with severe allergies or asthma. the shots start with a small amount of allergen. This
encourages the immune system to build up a tolerance to that allergen. This helps
the person to be less sensitive to the allergen, which results in fewer symptoms.
