Evolutionary biologist and prominent public figure Colin Wright recently disclosed a severe reaction to his second Moderna COVID-19 vaccine shot, while strongly cautioning against extrapolating individual experiences to the broader population. Wright, who holds a significant platform as an evolutionary biology PhD and fellow at the Manhattan Institute, shared his personal health details on social media. His statement underscores the importance of scientific data over anecdotal evidence in public health discussions.
Wright detailed his adverse experience, stating, "Yes, I had a very severe reaction to my second Moderna shot." He further revealed a pre-existing condition, noting, "I also have a rare autoimmune condition called Parsonage-Turner syndrome (diagnosed in 2013), so I may have been particularly vulnerable to side effects." This condition, also known as brachial plexopathy, is a rare neurological disorder characterized by sudden, severe pain in the shoulder and upper arm, followed by weakness and muscle wasting.
Despite his personal decision to avoid future mRNA vaccines due to this experience, Wright vehemently condemned the misuse of such anecdotes. "It would have been incredibly unscientific and highly irresponsible of me to take this personal experience of mine and start telling millions of people online to not get vaccinated for COVID," he stated in his tweet. He drew a parallel to "quack alternative medicine practitioners" who "plaster personal testimonies all over their websites" for manipulative purposes.
Wright emphasized that "Personal testimony, even a large collection of them, isn't a substitute for real, population-level data." He acknowledged his own limitations, asserting, "I am not an expert on vaccines, the COVID vaccine, or epidemiology in general." His severe reaction, he explained, was understood within the context of a "non-zero rate of serious side effects" for any medication, rather than an indication of widespread safety issues. He concluded by urging responsible scientists with large platforms to "resist that impulse" to generalize personal negative experiences.
