Vaccine Links

Alright, one of the most popular questions I get asked: can you share your resources on vaccines? I often have to reply with “no.” I last did really in-depth research on this subject when Wally was yet a baby. I wrote a 20 page paper on the subject; it was consequently lost in a computer crash.

I read things here and there, research smatterings of vaccine-related issues when they come up, but I haven’t systematically collected this information and, memory being what it is these days, rarely remember my sources after the initial need has passed.

But here, I’ll collect the information I come across as I come across it. Nothing from Hippie sources, only mainstream sources or actual research studies.    Waning of Maternal Antibodies…

The combined measles, mumps, and rubella (MMR) vaccine has been successfully administered for >20 years. Because of this, protection by maternal antibodies in infants born to vaccinated mothers might be negatively affected.
A large cross-sectional serologic survey was conducted in the Netherlands during 2006
–2007. We compared the kinetics of antibody concentrations in children and women of childbearing age in the highly vaccinated general population with those in orthodox Protestant communities that were exposed to outbreaks.
The estimated duration of protection by maternal antibodies among infants in the general population, most of whom were born to vaccinated mothers, was short: 3.3 months for measles, 2.7 months for mumps, 3.9 months for rubella, and 3.4 months for varicella. The duration of protection against measles was 2 months longer for infants born in the orthodox communities, most of whom had unvaccinated mothers. For rubella, mothers in the orthodox communities had higher concentrations of antibodies as compared to the general population.
Children of mothers vaccinated against measles and, possibly, rubella have lower concentrations of maternal antibodies and lose protection by maternal antibodies at an earlier age than children of mothers in communities that oppose vaccination. This increases the risk of disease transmission in highly vaccinated populations.
