According to data provided by the California Department of Public Health, six facilities associated with Google, IBM, Cisco, and Pixar fell below both the state average and what health care professionals recommend to prevent the spread of infectious diseases.

We have some further calibration of those numbers. The California DPH reported that a facility in San Jose run for IBM by the day care provider chain Bright Horizons had an immunization rate of 73 percent overall, with 89 percent of children having received the vaccine for measles, mumps, and rubella, or MMR. But a spokesperson for Bright Horizons, Julie Kane, says this data is inaccurate. According to the company's records, the San Jose facility has 105 kids enrolled, says Kane, including 12 infants who are too young to receive the MMR, which is first administered to children between the ages of 12 and 15 months.
