Nicole Shanahan, a prominent figure associated with the Children's Health Defense (CHD) organization, recently asserted that two peer-reviewed studies from 2015 "conclusively" revealed "measurable differences in the blood of children before receiving the vaccine and after." Shanahan, whose remarks were shared via a tweet from Children's Health Defense, claimed these studies indicated that "These vaccines impact the immune systems of children in really significant ways." She further alleged that these findings "couldn't get published for fear of retribution," expressing hope that "some of the information that’s been hidden from us" will now emerge.
Shanahan, who recently served as Robert F. Kennedy Jr.'s running mate in his presidential campaign, has frequently questioned the scientific consensus surrounding vaccine safety and efficacy. Her public statements and associations, including with CHD, align with a broader movement that promotes skepticism about established public health guidelines. Robert F. Kennedy Jr., founder of Children's Health Defense, has a long history of advancing debunked claims, notably linking childhood vaccines to autism and asserting that vaccine safety data is suppressed by government and mainstream medical institutions.
Despite these assertions, extensive searches for the specific "2015 peer-reviewed studies" detailing "measurable differences in the blood of children before receiving the vaccine and after" that were allegedly suppressed have not yielded verifiable results from reputable scientific databases. Mainstream scientific and medical organizations, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), consistently affirm the safety and efficacy of approved vaccines. These organizations state that vaccines undergo rigorous testing and continuous monitoring, and that claims of vaccines causing significant immune system harm or autism have been thoroughly debunked by a vast body of research.
The Children's Health Defense organization itself has been involved in legal challenges, including a lawsuit against Meta Platforms (Facebook) alleging censorship of vaccine-related content. Court documents from this case highlight CHD's view that their speech on vaccine safety has been suppressed. However, these legal proceedings primarily concern content moderation policies and not the scientific validity of the specific 2015 studies mentioned by Shanahan. The scientific community maintains that vaccines are a critical public health tool, preventing millions of deaths annually and significantly reducing the incidence of infectious diseases worldwide.
