Booster shots safer than initial COVID-19 vaccine doses: study

The study from health data science company nference found people who have had three doses of the same vaccine weren’t more likely to develop problems like myocarditis or anaphylaxis.

But booster shots were more likely to result in mild reactions like fatigue or nausea.

The study involved 48,000 Americans who had received Moderna or Pfizer vaccines.

The researchers noted the study may under-represent people who refused to get a booster shot after a bad reaction to the first two jabs.

The study from the San Francisco Veterans Affairs Health Care System and the University of California found people suffering from depression, anxiety, PTSD, bipolar disorders, ADHD and eating disorders were more likely to get sick from COVID-19.

This was despite the participants being double vaccinated. The study was conducted from February 2020 to November 2021, before booster shots were being used.

Though the researchers were careful to note while there was an observable link, there was no clear indication mental illness was linked to breakthrough infections.
