Approximately 200,000 infants per year in the U.S. (higher in Britain) develop autism, pervasive developmental disorder, or orther syndromes with severe cognitive malfunction as a result of vaccination of infants (Rubella and measles live attenuated viral vaccines are especially dangerous). Rubella vaccine can also precipitate Chronic Fatigue Immune Dysregulation Syndrome (CFIDS) in teenage girls vaccinated with Rubella vaccine to prevent infections and the resultant congenital malformations in the first trimester of pregnancy. Since Rubella in infancy is a very mild disease (three days of low-grade fever and rash), the risks for any given individual greatly outweigh the benefits. Indeed, the World Health Organization recommendations on infantile and childhood immunization include all other vaccines used in infants in this country with an increasing number of vaccines and increasing frequency thereof and is being reccomended by the WHO and by the department of Health and Human Services and CDC. Such immunizations though they may protect a given population carry risks for each individual, especially if immunizations are given duing the first 2.5 to 3 years of life when the CMI system is immature.
