The call comes after the doctor suffered his own COVID-19 vaccine adverse event.
Dr. Gregory Poland, the director of Mayo Clinic’s Vaccine Research Group, has called for more rigorous detection of vaccine adverse events after suffering a COVID-19 vaccine adverse event.
“While vaccines have an overwhelmingly positive safety profile, it’s essential to address concerns about potential adverse events comprehensively and compassionately,” Dr. Poland and his co-author Dr. Steve Black of the Global Vaccine Data Network wrote in their commentary published in the journal Vaccine.
“Some of these reactions are immediate and easily observable or measurable … Others however are not immediately obvious, or are even clinically ‘silent’ or cryptic, making them challenging to identify and link directly to a vaccine.”
Dr. Poland, the lead author, suffered from what he deemed a “cryptic” adverse event.
In 2021, soon after his second Moderna shot, Dr. Poland was driving back from the clinic when he suddenly heard a whistling sound in his ears.
“It was like someone suddenly blew a dog whistle in my ear,” he told MedPage Today. “It has been pretty much unrelenting.”
He has since attributed his tinnitus to the COVID-19 vaccine and become vocal in advocating for better vaccine adverse event surveillance programs.
“It is critical to be vigilant about rare, silent, or subtle reactions. Public health agencies and healthcare providers can play a much more favorable and vital role in establishing vaccine trust by enlarging the current vaccine safety paradigm,” Dr. Poland wrote.
Spectrum of Vaccine Adverse Events
Dr. Poland said a spectrum of adverse events exists; some are easily detectable, while others are far more hidden.
Swelling at the injection site and immediate fever, for example, are immediate, easily observed, and measurable. These are thus far easier to detect and link to the vaccine if the symptoms come on soon after vaccination.
Dr. Poland reasoned that an adverse event’s detectability differs by whether it can be measured or imaged, if biomarkers are present, and if the condition is responsive to treatment.
