Type of vaccine in which the source of the antigen material is the patient who is to be vaccinated

The type of vaccine in which the source of the antigen material is the patient who is to be vaccinated is known as an Autologous vaccine.

Here are the steps involved in creating an autologous vaccine:

1. Collection: The first step is to collect the antigen material from the patient. This could be a sample of tissue or cells, such as a tumor cell in the case of cancer vaccines.

2. Processing: The collected material is then processed in a laboratory. This could involve breaking down the cells to extract the antigens, or in some cases, modifying the cells to enhance their immune-stimulating properties.

3. Formulation: The processed antigens are then formulated into a vaccine. This could involve combining them with other substances that help to stimulate an immune response, such as adjuvants.

4. Administration: The final step is to administer the vaccine back into the patient. This is usually done through an injection.

The idea behind autologous vaccines is to stimulate the patient's own immune system to recognize and attack the specific antigens that are present in their body. This can be particularly useful in situations where the antigens are unique to the patient, such as in the case of personalized cancer vaccines.
