Efficacy of Vaccines
Question:
Here are a few reasons (with references of course) why I have reversed my original belief in the efficacy of vaccines: -> The CDC reported measles outbreaks in a documented 100% vaccinated population (Morbidity and Mortality Weekly Report [MMWR], 33(24), 6/22/84) -> In 1989 the CDC reported "Among school-aged children (measles) outbreaks have occurred in schools with vaccination levels of greater than 98%. These outbreaks have occurred in all parts of the country, including areas that had not reported measles for years" (MMWR, 38(S- 9), 12/29/89) -> To combat this resurgence of measles, the CDC and the AAP (American Academy of Pediatrics) recommended a second dose of the MMR vaccine just before kindergarten, seventh grade, or when entering college. Evidently, this approach didn’t work either. According to The Pediatric Infectious Disease Journal (13(1), 34-38, 1994): "Thus even after the recommended two dose schedule of the current measles vaccine, some adolescents and young adults lack protective titers of measles- specific antibody…In addition, women lacking protective titers will provide little or no measles-specific antibody transplacentally to their infants. These children will be susceptible to measles infection virtually from birth, and are at much higher risk for complications when infected at younger ages" ***MY EDITORIAL*** The significant measles morbidity and mortality in infants during the 1980’s U.S. measles resurgence could be blamed on government mass vaccination programs. Since vaccinated mothers possess only short-term measles immunity, and do not pass this immunity to their babies transplacentally, these infants are left defenseless again measles, which can be quite serious in infancy. In past years, when women caught measles as children, and acquired strong lifelong immunity, they passed measles antibodies to their babies during pregnancy, giving the newborn measles immunity for about a year.

Vaccination is not 100%. A better question would be, "did the vaccinated population have less disease than an unvaccinated population?" The epidemiological data (see MMWR) would certainly support the efficacy – granted not 100% efficacy – of the MMR vaccine. > -> In 1989 the CDC reported "Among school-aged children (measles) > outbreaks have occurred in schools with vaccination levels of greater > than 98%.

In these outbreaks, the unvaccinated children have a much higher incidence of the epidemic disease. You are taking the above statement out of context. > -> To combat this resurgence of measles, the CDC and the AAP (American > Academy of Pediatrics) recommended a second dose of the MMR vaccine > just before kindergarten, seventh grade, or when entering college. > Evidently, this approach didn’t work either.

Yep, we know that the MMR vaccine does not confer 100% immunity, but it does confer >90% immunity. See: Johnson CE, Darbari A, Darbari DS, Nalin D, Whitwell J, Chui LW, Cleves MA, Kumar ML. Measles vaccine immunogenicity and antibody persistence in 12 vs 15-month old infants. Vaccine. 2000 May 1;18(22):2411-2415. > In addition, women lacking protective titers will > provide little or no measles-specific antibody transplacentally to > their infants.

Also true. However women who have not been vaccinated and who have not contracted the disease will also convey no passive immunity. Women who have been vaccinated and who do have protective titers will provide passive antibodies. The best and safest approach for infants is to have them avoid unvaccinated children and adults. The easiest way to do that is to vaccinate all children. To be 100% certain, we could then test vaccinated children to determine whether they have seroconverted with two doses of vaccine and revaccinate the 2-6% who have not. There is some literature available about the amount of measles antibodies present in breast milk. Even in the unvaccinated population, it appears to be an extremely small amount. See: Adu FD, Adeniji JA. Measles antibodies in the breast milk of nursing mothers. Afr J Med Med Sci. 1995 Dec;24(4):385-8. Choi EK, Lawton JW.

Your editorial is incorrect in its assumptions. There wasn’t much of a 1980’s "measles resurgence". Most of the measles cases that occurred in that time period were among college students who were either not vaccinated or who were vaccinated in the early 1960s with killed vaccine rather than the attenuated, live vaccine used in since 1967. Most children who were affected were infants who had not yet been vaccinated. The number of children affected by the 1980s "epidemic" was a tiny fraction of the number afected prior to mass immunization. You are also confused about the difference between passive and active immunization. Mothers need to breast feed for the a year to provide a year’s worth of passive antibodies. Vaccinated mothers do not possess "only short term immunity", but either way, there doesn’t seem to be a whole lot of protection from breast feeding alone. However, population studies should probably done to determine whether adults need MMR boosters. I was born in 1959 and vaccinated with the killed virus. I was re-vaccinated in 1992 with the attenuated virus. > TO BE CONTINUED > Jessica
The following is an interesting study. In one age group, 5 to 9 year olds, the lack of measles vaccine was found to be a risk factor for diabetes (i.e. the vaccinated children were less likely to have diabetes).

Dr. Holmes had some quite negative comments about homeopathy. I suspect he would have had no higher an opinion of chiropractic. — Democracy is the worst form of government except all those other forms that have been tried from time to time. — Winston Churchill Search peer reviewed medical literature yourself at http://www.ncbi.nlm.nih.gov/PubMed/ View U.S. health statistics at http://www.cdc.gov/nchs/
