Repeated contact with mumps may overwhelm immunization

A recent study, published in The New England Journal of Medicine, concluded that after an intense face-to-face educational technique, used among Orthodox Jews, apparently led to an outbreak of mumps in 2009 and 2010, despite high vaccination rates in the group. In a one-year period, from June 28, 2009, through June 27, 2010, 3,502 cases of mumps were reported in New Jersey, New York City and New York’s Orange and Rockland counties. The study examined 1,648 of those cases, 97% were Orthodox Jews, and found 89% had received two doses of the vaccine and 8% received one dose, a relatively high rate of vaccination.

Many of the individuals attended a religious school where they practiced an intense training technique called chavruta, which involves close contact with a partner across a narrow table. Partners change frequently, and he discussion is often loud and may involve shouting since a larger group may be close to each other, all trying to make an argument or point. This prolonged contact overwhelmed the immunity, from the mumps vaccination (part of the MMR vaccine), for individuals. The study did find high rates of two-dose coverage reduced the severity of the disease and the transmission to people in settings of less exposure. Also, the study found that mumps did not spread outside of the Orthodox Jewish community in the area, further supporting the overall effectiveness of the mumps vaccine in the broader community.

Measles case confirmed at New York state school

The Dutchess County (NY) Department of Health, in New York’s mid-Hudson Valley, have confirmed a measles case at the Mountain Laurel Waldorf School in New Paltz, NY. The local Departments of Health are recommending that anyone “who has visited this school since September 10th or has had any contact with anyone from this school should immediately make sure that they are up to date with their measles vaccinations.  All medical practices and laboratories in the area should be on high alert that there may be a number of other children and families who have been exposed and could be communicable.”

Nirav R. Shah, the New York state health commissioner, has stated that almost half of the students have not received measles immunizations (MMR vaccine).  Measles immunization is a requirement in the state, but private schools have the authority to make exceptions. The kindergarten and elementary, which has slightly more than 130 students enrolled, is a private school is located in the New Paltz college community.  Continue reading “Measles case confirmed at New York state school”

Erin Brockovich to probe New York ‘mass hysteria’ case

Erin Brockovich to probe New York ‘mass hysteria’ case – latimes.com.

Erin Brockovich is really getting involved with the cluster of alleged neurological issues in teenagers in the Leroy, NY area.  The article describes the symptoms as “Tourette’s-like”, but I’m troubled by the lack of a definitive description (let alone diagnosis).  Brockovich, as discussed previously, is still focused on the 1970’s train derailment which spilled arsenic and tricholorethylene.  The speculation about what is causing these issues run from mass hysteria, even outright feigned behavior, to something environmental, such as vaccines or chemicals.

It’s hard to tell what’s going on.  I am almost certain that during the next few days or weeks, the Centers for Disease Control (CDC) will get involved, interviewing and testing the students, and trying to determine if there is some correlation and possible causal factor.  We probably should wait until the real scientists get involved and provide some real analysis with evidence.
