Study Reveals Side Effects of COVID-19 Vaccines – The People’s Pharmacy

Back in the summer of 2020, people could hardly wait for COVID-19 vaccines to be developed so that the pandemic would end. Within a few months, people were starting to report side effects such as Bells palsy or a false-positive result on mammograms. A new study published in the journal Vaccine reveals some interesting discoveries about the side effects of COVID-19 vaccines (Vaccine, Feb. 12, 2024).

This study, called the Global Vaccine Safety Project, included 99 million people from eight countries. Australia, Canada, Argentina, Denmark, Finland, France, New Zealand and Scotland participated. All vaccinated large numbers of people and have good health records for tracking the outcomes.

In general, serious side effects were rare. The researchers predicted how frequently a severe complication might occur based on the rates before the pandemic began. For example, they estimated rates of myocarditis, or inflammation of the heart muscle, in a healthy unvaccinated population. This problem was twice as common following vaccination. Nonetheless, there were relatively few cases.

Guillain Barr syndrome, a neurological complication that causes temporary paralysis, was more common after the AstraZeneca vaccine. The researchers predicted 76 cases of Guillain Barr in healthy unvaccinated people. They actually observed 190 cases. Thats about 2.5 times more than baseline.

Another serious, but rare complication was acute disseminated encephalomyelitis following the Moderna vaccination. Scientists expected 2 cases among 10 million people vaccinated. Instead, they reported 7.

The conclusion seems to be that COVID vaccines do indeed cause vascular and neurological adverse reactions, but the overall incidence is low. An independent study of COVID-19 vaccines demonstrated that vaccinated individuals have a reduced risk for severe outcomes, including Long COVID (Vaccines, Feb. 2024).
