Officials at a Los Angeles high school said Tuesday that a lack of vaccinations does not explain an outbreak of whooping cough.
Thirty students at the private school have reportedly been diagnosed with whooping cough, also known as pertussis, recently.
Engelberg also told reporters that only 18 of Harvard-Westlake’s roughly 1,600 students have medical exemptions allowing them to opt out of immunizations. He added that none of those students have contracted the disease.
Los Angeles County officials warned area doctors in an email last week about three clusters in the county, according to the Times.
