My anecdotal impression is that many traditional Orthodox Jews in Los Angeles do not get vaccinated for measles etc.
A measles outbreak in Los Angeles County, California, is centered on the Orthodox Jewish community, according to reports.
Some 20 people have been infected in the outbreak, with 18 in LA County, 15 of whom, according to the LA County Department of Public Health “either knew one another or had a clear social connection, ” the Los Angeles Times reported over the weekend.
None of the 18 people could show proof of vaccination, according to the health department’s interim health officer Dr. Jeffrey Gunzenhauser. Most of those infected were in their 20s but the infected also included young children and older adults, according to the newspaper.
The outbreak comes six months after California passed a strict vaccine law, making vaccines mandatory beginning in first grade.
