Developing Vaccines to Target Cancer's Blood Vessels

The video discusses a vaccine that stimulates the immune system to attack cancer by targeting both the tumor and its blood supply. The challenge lies in the tumor's genetic similarity to normal cells, which the immune system typically does not attack. The vaccine employs a dual approach: encouraging the immune system to recognize cancer as an infection and countering the blood supply increase to tumors. While not a universal solution, the vaccine could benefit 20% of patients with major solid cancers.

What is the dual approach of the vaccines discussed in the video?

• Blocking cancer cell division and enhancing nutrition

• Increasing white blood cells and reducing tumor size

• Directly attacking cancer cells and boosting metabolism

• Stimulating immune response and targeting tumor blood vessels

Why is it challenging for the immune system to attack tumors?

• Tumors are protected by a special shield

• Tumors are too small to detect

• Tumors share the same genetic code as normal cells

• The immune system is too weak

What strategy is used to help the immune system recognize cancer cells?

• Increasing the temperature around cancer cells

• Using antibiotics to weaken cancer cells

• Labeling cancer cells with a special dye

• Encouraging the immune system to see cancer as an infection

How does the vaccine target the tumor's blood supply?

• By shrinking the blood vessels

• By recognizing and countering the mechanism that increases blood supply

• By redirecting blood flow to other parts of the body

• By freezing the blood vessels

What percentage of patients with major solid cancers might benefit from the vaccine?

• 30%

• 50%

• 10%

• 20%
