But the author wrote
“Antibodies derived from natural infection with COVID-19 are more abundant and more potent….”

The whole point of her article was natural immunity (only from infection) is better than (or at least as good) immunity from vaccination. She started her article misrepresenting the results from the linked study which did not compare antibody levels from just infection vs antibody levels from vaccination.
