Studies and Research
The body of research on the effects of intramuscular injections is vast and detailed. However, the highly technical language in these studies can be difficult for the general public to understand.
In public health research, authors often soften their wording due to pressure from journals to downplay negative findings on side effects and adverse reactions. As a result, important insights are frequently obscured or carefully phrased in the papers themselves—though they remain visible in the data sets and discussion sections upon close review.
To address this, HFDF has created this searchable compendium of studies, each paired with clear, plain-language summaries and notes prepared by our team. Our goal is to cut through technical complexity, bias, and ambiguity so individuals can access the key facts and make informed health decisions.
This resource will continue to grow, with new studies and improvements added regularly.
Please note that HFDF does not necessarily endorse or support any policy arguments or specific assumptions made by the authors. HFDF commentary describes and summarizes the role this study plays in the scientific discourse and provides abbreviated notes.

Preliminary Findings of mRNA Covid-19 Vaccine Safety in Pregnant Persons
This CDC study was used early to claim broad safety of mRNA vaccines in pregnant women in 2021, and as evidence to censor dissent online. It is now notorious for methodological fraud (found in original table 4) which resulted in a large NEJM correction but not a retraction. Lack of promised follow-up, and possible data destruction by this team is under investigation by a US Senator. Initially, this study claimed that miscarriage and stillbirth rate among vaccinated women generally was similar to rate of general population, but used statistical sleight of hand to achieve that result. Upon outcry and correction, the key claims were nullified but the media had already circulated them and never corrected them at scale in the public record.
