A new study on COVID-19 vaccines that looked at nearly 100 million vaccinated individuals affirmed the vaccines’ previously observed links to increased risks for certain adverse effects including myocarditis and Guillain-Barré syndrome.
The study was conducted by the Global COVID Vaccine Safety project and took into account 99,068,901 vaccinated individuals across eight countries: Argentina, Australia, Canada, Denmark, Finland, France, New Zealand and Scotland.
The report specifically looked at adverse events following administration of the Pfizer, Moderna and AstraZeneca vaccines.
The researchers looked for 13 adverse events of special interest that occurred in vaccine recipients for up to 42 days after shots were administered. These conditions included Guillain-Barré syndrome, Bell’s palsy, convulsions, myocarditis and pericarditis.
Researchers observed a “significant increase” in cases of Guillain-Barré syndrome among those who received the AstraZeneca vaccine with 42 days of administration.
They also noted higher-than-expected instances of acute disseminated encephalomyelitis (ADEM), inflammation of the brain and spinal cord, among those who received their first dose of Moderna’s vaccine.
