The real bio-threat:

Currently the United States is experiencing shortages of eight of the eleven vaccines required by law for children: measles, mumps, rubella, diphtheria, tetanus, pertussis (whooping cough), varicella (chicken pox), and pneumococcal disease (meningitis). In response, the Centers for Disease Control (CDC) have revised their immunization schedule from “optimal” to “some protection,” which means that, depending on the vaccine, kids may get the first shot and not the boosters that solidify immunity, or they may not get the first shot at all until several months past the recommended age. In response to the shortages, some states are relaxing their demands that kids get vaccinated before they come to school this September. In Oregon, for example, seven-year-olds will be allowed to forgo chicken pox shots and diphtheria/tetanus boosters; Texas is deferring the diphtheria/tetanus booster shot required for all 14-year-olds. Which is scary, because children aren’t the only ones at risk: Spotty vaccination cycles for diseases such as rubella and chicken pox mean that children may grow to adulthood without immunity, remaining at risk for diseases that cause many more complications for adults and can have devastating effects for pregnant women.
