No, because this claim that "more than 90 percent" of ob-gyns in
California "refused" to be vaccinated is utter bullshit.

... died in 1988.

Also, stating a "statistic" without saying where the original data come from
is meaningless.

Actually the question "Is 90% statistically significant?" is
meaningless. I'll post the actual abstract that seems to be
referred to in this quotation and why don't you honestly post
whether you think this information from 1981 is of any relevance
to anything:

Rubella vaccine and susceptible hospital employees. Poor physician
participation.

Orenstein WA, Heseltine PN, LeGagnoux SJ, Portnoy B.

A serosurvey of 2,456 high-risk employees of the Los Angeles
County-University of Southern California Medical Center showed that 345
(14%) were susceptible to rubella. Of 197 seronegative personnel
followed up for participation in a vaccination program, 105 (53.3%) were
vaccinated. However, only one of the 11 known susceptible
obstetrician-gynecologists was vaccinated. Thirty-eight seronegative
employees who were vaccinated with RA 27/3 rubella vaccine were queried
four to six weeks after vaccination and compared with 32 unvaccinated
seropositive control subjects. Although the reaction rate was 50% among
vaccinees and 3% among control subjects, each vaccinee lost only an
average of 0.2 workdays compared with 0.1 workdays for control subjects.
The high rate of susceptibility to rubella among hospital employees
supports the need for screening. Although vaccine reactions are common,
they are generally mild. Means must be found to ensure greater employee
acceptance of vaccine.

So to ask this another way, do you believe it is significant that
in 1981 they could only get one out of eleven obstetricians who
had not already been vaccinated to show up for vaccination.

Note that the above quote from Dr. Mendelsohn is a complete
distortion of what the study showed. It did not find that more
than 90& of obstetricians in California refused vaccination. It
dealt only with eleven obstetricians in California who presumably
had already neither been vaccinated nor developed natural immunity
to rubella.
