California's AB 2109 was passed into law in 2012 and takes effect January 1, 2014. The new CA law (http://leginfo.legislature.ca.gov) will require parents exercising an exemption to immunizations to provide a letter or affidavit to document which required immunizations have been given and which have not been given on the basis that they are contrary to the parent's beliefs; and beginning on January 1, 2014, the letter or affidavit has to be accompanied by a State Department of Public Health form signed by a health care practitioner saying that he or she provided the parent "information regarding the benefits and risks of the immunization and the health risks of specified communicable diseases," and a written statement by the parent indicating that he or she received the information from the health care practitioner. (Seriously? the doctor's signature alone is not convincing?) California's Governor Brown, when signing AB 2109 into law, directed the Department of Public Health to allow for a separate religious exemption on the form, so that people whose religious beliefs are opposed vaccinations won't be required to seek a health care practitioner's signature. The Department complied, and included a religious exemption in its form.
