The unvaccinated do not put the vaccinated at risk.
It is often claimed that those who choose not to vaccinate their children for reasons of conscience endanger the rest of the public, and this is the rationale behind most of the legislation to end vaccine exemptions. It should be noted that the nature of the protection afforded by many modern vaccines - which includes most of the vaccines recommended by the CDC for children - is not consistent with such a statement.
The list of vaccines below cannot prevent the transmission of the disease, either because they are not designed to prevent the transmission of the infection (rather, they are intended to prevent the symptoms of the disease), or because they are for diseases non-communicable. People who have not received the vaccines do not pose a threat to the general public who have received them, which implies that discrimination against unimmunized children in a school is not justified.
Diseases and Contagion
IPV (inactivated poliovirus vaccine)it cannot prevent the transmission of the polio virus. Wild poliovirus has been non-existent in the US for at least two decades. Even if wild poliovirus is re-imported by travelers, vaccination against polio with IPV cannot affect the safety of public spaces. Note that the eradication of wild poliovirus is attributed to the use of a different vaccine, the vaccine, OPV, or oral polio. Despite being able to prevent the transmission of wild poliovirus, the use of OPV was phased out long ago in the US and replaced with IPV due to safety concerns.
Tetanus is not a contagious disease, but rather acquired from deep-puncture wounds contaminated with C. tetani spores. Vaccination against tetanus (through the combined DTaP vaccine) cannot alter the safety of public spaces; it only gives personal protection.
While intended to prevent the disease-causing effects of diphtheria toxin, the diphtheria toxoid vaccine (also contained in the DTaP vaccine) is not designed to prevent colonization and transmission of C. diphtheriae. Diphtheria vaccination cannot alter the safety of public spaces; it is useful only for personal protection.
Whooping Cough - Pertussis
The acellular pertussis (aP) vaccine (the final element of the DTaP combination vaccine), now in use in the US, replaced the whole cell pertussis vaccine, beginning in the late 1990s and there was a unprecedented resurgence of whooping cough. An experiment with pertussis infection in primates revealed thatthe aP vaccine is not able to prevent colonization and transmission of B. pertussis. The FDA has issued a warning regarding this crucial finding. [one]
At the 2013 meeting of the CDC Scientific Advisory Council, he revealed alarming additional data on pertussis variants (PRN-negative strains) currently circulating in the US that gained a selective advantage in infecting those who are up to to date with their DTaP boosters, which means that people who are up to date are more likely to be infected, and therefore infect, which people who are not vaccinated do not.
Influenza - Flu
Among the many types of H. influenza, the Hib vaccine covers only type b. Despite its sole intention to reduce symptomatic and asymptomatic Hib (decrease disease),the introduction of the Hib vaccine has inadvertently shifted the dominance of the strain to other types of H. influenza (types a to f). These types have been causing invasive disease of high severity and increasing incidence in adults, in the era of Hib vaccination of children. The general population is more vulnerable to invasive disease now than it was before the start of the Hib vaccination campaign. Discriminating against children who are not vaccinated for Hib makes no scientific sense in the era of H. influenza type b non-disease.
Hepatitis B is a blood-borne virus. It is not spread in a community setting, especially among children who are unlikely to engage in high-risk behaviors, such as sharing needles or sex. Vaccination of children against hepatitis B cannot alter the safety of public spaces. Also, school admission is not prohibited for children who are carriers of chronic hepatitis B. To ban school admission for those who are simply not vaccinated - and do not even carry hepatitis B - would constitute unreasonable and illogical discrimination.
