Sheri Nakken, R.N., MA :

A nurse over at BabyCenter brought this information to my attention.
Evidently there is a study published in the Journal of Infectious Diseases
which shows that the measles vaccine (yes, the single measles-the one that
most folk believe is safe if given alone) interferes with interferon
production. Big deal, you say?

Well, turns out interferon is a necessary chemical produced by lymphocytes (a
type of white blood cell). Interferon assists the host to be resistant to
infection and interferon's production is stimulated by infection with a
virus. Production of interferon is a good thing because its purpose is to
protect the body from superinfection by some other micro-organism.

In the study, one-year-old infants were vaccinated with the measles vaccine.
This caused a huge drop in the level of alpha-interferon produced by
lymphocytes. Not only that, this harmful reduction in interferon production
lasted for an entire year, at which time the experiment was ended.

Conclusion: The study showed that the measles vaccine produced a significant
long-term immune suppression.
