"Public health" has been so perverted and distorted under the government / pharmaceutical collusion regime that instead of teaching people how to prevent disease with nutritious foods, vitamin D and low-cost natural cures, the government is all about injecting infants with vaccines, irradiating women's breasts with mammograms, and outlawing dietary supplements while claiming to be working under the label of "public health."The CDC letter suggests that the survey is voluntary, so thank goodness for caller ID.
...The government is now admittedly using weapons technology companies, phone surveillance techniques, immunization tracking and statistical analysis to find out who is not being vaccinated. These are police state tactics now being used by the vaccine industry -- in collusion with dangerous government mandates and rogue CPS agents -- to attack your freedom of choice and your right to make parental decisions about the health of your child.
