Pregnancy Can Help Fight Cancer

Pregnancy can reduce the risk of cancer. This happens because some of the fetus’s cells cross the placenta and settle into the bloodstream and other tissues. The cells from the fetus increase the amount of immunity against breast cancer. This finding could help in the development of a breast caner vaccine in the future.

New Vaccine for Cocaine Addicts

Scientists are currently working on a vaccine that could prevent cocaine addicts from getting a high from the drug. The vaccine contains inactivated cocaine molecules that are attached to pieces of the inactivated cholera virus. When the vaccine is injected into the body, it trains the body’s immune system to see the drug as an invader. If the vaccinated cocaine addict takes cocaine, antibodies surround and attack themselves to the cocaine molecules and prevent them from reaching the brain to create that sense of feeling high. For people that want to stop using cocaine and kick the habit, the vaccine could be very useful.
