Harvard Unvaccinated Children Pose Zero Risk. A Harvard immunologist has written an open letter explaining why unvaccinated children pose no risk to their vaccinated counterparts. Vaxxter. Dear Legislator My name is Tetyana Obukhanych. I hold a Ph. D in Immunology. I am writing this letter in the hope that it will correct several common misperceptions about vaccines in order to help you formulate a fair and balanced understanding that is supported by accepted vaccine theory and new scientific findings. Do unvaccinated children pose a higher threat to the public than the vaccinated It is often stated 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 currently being considered by federal and state legislators country wide. You should be aware that the nature of protection afforded by many modern vaccines and that includes most of the vaccines recommended by the CDC for children is not consistent with such a statement. I have outlined below the recommended vaccines that cannot prevent transmission of disease either because they are not designed to prevent the transmission of infection rather, they are intended to prevent disease symptoms, or because they are for non communicable diseases. People who have not received the vaccines mentioned below pose no higher threat to the general public than those who have, implying that discrimination against non immunized children in a public school setting may not be warranted. IPV inactivated poliovirus vaccine cannot prevent transmission of poliovirus. Wild poliovirus has been non existent in the USA for at least two decades. Even if wild poliovirus were to be re imported by travel, vaccinating for polio with IPV cannot affect the safety of public spaces. Please note that wild poliovirus eradication is attributed to the use of a different vaccine, OPV or oral poliovirus vaccine. Despite being capable of preventing wild poliovirus transmission, use of OPV was phased out long ago in the USA and replaced with IPV due to safety concerns. Tetanus is not a contagious disease, but rather acquired from deep puncture wounds contaminated with C. Vaccinating for tetanus via the DTa. P combination vaccine cannot alter the safety of public spaces it is intended to render personal protection only. While intended to prevent the disease causing effects of the diphtheria toxin, the diphtheria toxoid vaccine also contained in the DTa. P vaccine is not designed to prevent colonization and transmission of C. Results. Screening was completed in 8514 patients with singleton pregnancies. This approach to screening identified 85.

Board of Scientific Counselors at the CDC revealed additional alarming data that pertussis variants PRN negative strains currently circulating in the USA acquired a selective advantage to infect those who are up to date for their DTa. P boosters, meaning that people who are up to date are more likely to be infected, and thus contagious, than people who are not vaccinated. Among numerous types of H. Hib vaccine covers only type b. Despite its sole intention to reduce symptomatic and asymptomatic disease less Hib carriage, the introduction of the Hib vaccine has inadvertently shifted strain dominance towards other types of H.

Down Syndrome Screening Risk Calculation Software' title='Down Syndrome Screening Risk Calculation Software' />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 the invasive disease now than it was prior to the start of the Hib vaccination campaign. Discriminating against children who are not vaccinated for Hib does not make any scientific sense in the era of non type b H. Hepatitis B is a blood borne virus. It does not spread in a community setting, especially among children who are unlikely to engage in high risk behaviors, such as needle sharing or sex. Vaccinating children for hepatitis B cannot significantly alter the safety of public spaces. Further, school admission is not prohibited for children who are chronic hepatitis B carriers. To prohibit school admission for those who are simply unvaccinated and do not even carry hepatitis B would constitute unreasonable and illogical discrimination. In summary, a person who is not vaccinated with IPV, DTa. P, Hep. B, and Hib vaccines due to reasons of conscience poses no extra danger to the public than a person who is. No discrimination is warranted. How often do serious vaccine adverse events happen It is often stated that vaccination rarely leads to serious adverse events. Unfortunately, this statement is not supported by science. A recent study done in Ontario, Canada, established that vaccination actually leads to an emergency room visit for 1 in 1. When the risk of an adverse event requiring an ER visit after well baby vaccinations is demonstrably so high, vaccination must remain a choice for parents, who may understandably be unwilling to assume this immediate risk in order to protect their children from diseases that are generally considered mild or that their children may never be exposed to. Can discrimination against families who oppose vaccines for reasons of conscience prevent future disease outbreaks of communicable viral diseases, such as measles Measles research scientists have for a long time been aware of the measles paradox. I quote from the article by Poland Jacobson 1. Failure to Reach the Goal of Measles Elimination Apparent Paradox of Measles Infections in Immunized Persons. Arch Intern Med 1. The apparent paradox is that as measles immunization rates rise to high levels in a population, measles becomes a disease of immunized persons. Further research determined that behind the measles paradox is a fraction of the population called low vaccine responders. Low responders are those who respond poorly to the first dose of the measles vaccine. These individuals then mount a weak immune response to subsequent RE vaccination and quickly return to the pool of susceptibles within 2 5 years, despite being fully vaccinated. Re vaccination cannot correct low responsiveness it appears to be an immuno genetic trait. The proportion of low responders among children was estimated to be 4. USA. 5Studies of measles outbreaks in Quebec, Canada, and China attest that outbreaks of measles still happen, even when vaccination compliance is in the highest bracket 9. This is because even in high vaccine responders, vaccine induced antibodies wane over time. Vaccine immunity does not equal life long immunity acquired after natural exposure. It has been documented that vaccinated persons who develop breakthrough measles are contagious. In fact, two major measles outbreaks in 2. An error occurred while setting your user cookie.
