What are the Challenges in Developing Therapeutic Vaccines?
Developing therapeutic vaccines presents several challenges. One major hurdle is ensuring the [safety and efficacy](https://www.fda.gov/vaccines-blood-biologics/development-approval-process-cber) of the vaccine, as it must effectively target diseased cells without causing harm to healthy tissues. Additionally, the immune system of individuals with chronic diseases may be compromised, making it harder to achieve a robust immune response. Another challenge is the high cost and lengthy process of vaccine development, which includes extensive clinical trials and regulatory approvals.
