For the past 25 years, scientists have been developing a new class of birth control methods -- immuno-contraceptives, also known as an anti-fertility “vaccines” -- which aim to turn the body’s immune system against reproductive components. Immuno-contraceptives are likely to be unreliable as far as an individual is concerned and to entail an unprecedented potential for abuse; severe health risks cannot be discounted. They are a clear example of the impact “population control” has had on contraceptive research.
