Despite a California law passed after the 2015 Disneyland measles outbreak that got rid of the "personal belief" vaccine exemptions for children entering school, pockets of low vaccination rates have developed in the state. A number of counties are reporting rates lower than 90 percent, the number needed to achieve herd immunity, which occurs when enough people are vaccinated against an infectious disease to protect others in the community who are not.That is likely due to a surge in medical exemptions— a doctor's note allowing a child to go to school without the required vaccinations, according to research published October in the journal Pediatrics. In some schools the medical exemption rate is as high as 20 percent, according to the California Department of Public Health.
California parents opposed to vaccinations have found a way around the law, with help from doctors willing to write medical exemptions for kids who don’t need them. The Pediatrics study found some medical exemptions were being given with inadequate justification, such as “family history of allergies and family history of autoimmune disorders.”..
The study revealed that the exemptions were being generated by doctors who don’t normally treat children and were “coming from physicians who were charging fees.”While some doctors appeared to charge a single fee for a permanent exemption, the researchers discovered that some were giving temporary exemptions, say for three months at a time, and then charging a new fee for each additional exemption...Richard Pan doesn’t mince his words when he talks about the doctors “selling” exemptions: “The thing we need to recognize is that many of the physicians who have broken their oath, they’re doing it for their own pocketbook. It’s not based on their expertise. They’re monetizing their license,” he told NBC News.
There are of course perfectly valid indications to not be vaccinated, primarily based on impaired host immunity (bone marrow transplant, chemotherapy). But these doctors are gaming the system for personal profit. More at NBC News.
