What are the challenges in developing cancer vaccines?
Developing cancer vaccines is challenging due to the complexity of the immune system and the diversity of cancer types. Cancer cells originate from normal cells, making it difficult for the immune system to recognize them as threats. Moreover, each type of cancer has unique antigens, necessitating different vaccine formulations for effectiveness. Despite these challenges, progress is being made, with successful vaccines for HPV-related cervical cancer and ongoing research into personalized cancer vaccines.
