A former Chicago White Sox pitching prospect has launched legal action against the club, alleging he was pressured into receiving the COVID-19 vaccine and that the injection caused a permanent autonomic nervous system disorder that brought his professional baseball career to an abrupt end.
Isaiah Carranza, who was drafted by the White Sox in 2018, claims team officials told him refusing the two-dose vaccine would effectively end his chances of continuing in professional baseball, warning he could be blacklisted from the sport if he did not comply.
According to the lawsuit the vaccine requirement applied to minor league players while major league athletes were not subject to the same pressure because of union protections negotiated through Major League Baseball. Carranza argues that minor league players had little bargaining power and faced losing their careers if they declined.
The legal filing states that shortly after receiving the Pfizer-BioNTech COVID-19 vaccine, Carranza began suffering severe dizziness, nausea, episodes of near-fainting, and major fluctuations in heart rate. He alleges club medical staff initially attributed the symptoms to dehydration, anxiety, and the pressures of being a young player entering professional baseball.
His lawyers say the condition caused permanent damage to his autonomic nervous system, ending his pitching career before it had fully developed. They estimate future medical treatment could cost more than $557,000, while projected lost earnings range between $3.4 million and $19.9 million.
The case also revives wider debate over vaccine mandates introduced across professional sport, universities, and workplaces during the pandemic, particularly around whether lower-tier athletes and workers had meaningful freedom to refuse.
Carranza’s legal team argues that vaccine injury compensation pathways have been difficult to access, noting that although more than 14,000 claims have reportedly been lodged through compensation programmes, only a small number have qualified for payment.
