Joseph Moran v. HHS - Influenza, rheumatoid arthritis (2021)

Joseph Moran, a 55-year-old male, received an influenza vaccine on October 17, 2013. He filed a petition alleging that this vaccine caused him to develop rheumatoid arthritis (RA).

The court considered the medical records, expert reports from Dr. Thomas Zizic for the petitioner and Dr.

Mehrdad Matloubian for the respondent, and testimony from both experts. The petitioner's expert, Dr.

Zizic, opined that the flu vaccine caused Mr. Moran's RA through molecular mimicry, a theory involving the immune system mistakenly attacking the body's own tissues due to similarities between viral antigens and self-antigens.

He argued that Mr. Moran had no prior rheumatic symptoms and that the vaccine was the only significant immune system perturbation at the time of symptom onset.

The respondent's expert, Dr. Matloubian, countered that there is no established link between the flu virus and RA, and that the molecular mimicry theory was not supported by the evidence, particularly the studies cited which did not demonstrate that the same T cells recognize both influenza and collagen peptides.

Dr. Matloubian also highlighted that RA is generally understood to develop over years, with autoantibodies often preceding clinical symptoms by several years, making a rapid onset after vaccination unlikely.

Furthermore, Dr. Matloubian pointed to Mr.

Moran's history of smoking as a significant risk factor for RA, even though he had quit many years prior, as the "insult" of smoking could have initiated a process that continued to develop. The court found that the petitioner failed to establish a sound and reliable medical theory connecting the flu vaccine to RA (Althen Prong One).

The court also found that the petitioner did not prove a logical sequence of cause and effect, noting the lack of persuasive evidence from treating physicians and the presence of alternative risk factors like smoking (Althen Prong Two). While the court found that Mr.

Moran did experience symptoms consistent with RA onset within days of vaccination, it concluded there was insufficient evidence that this timeframe was medically acceptable for RA onset following a flu vaccine, especially given the understanding that RA develops over years (Althen Prong Three). Consequently, the court denied the petition.
