People who received mRNA COVID-19 vaccines may be experiencing mood swings and hormonal imbalances due to spike protein damage to the pineal gland, a top researcher claims.

Fabio Zoffi, the founder of Zero Spike – an organization researching spike protein toxicity and detoxification – described an Italian pathologist's discovery showing spike proteins damage the pineal gland, a pea-sized organ inside the brain that regulates sleep, mood and hormones, causing erratic personality changes in vaccinated people.

"I want to add also a comment…about the change in personality, depression, and all these things," Zoffi told a group of researchers during a People's Health Alliance roundtable in August 2023.

"This is very real. And we have identified the reasons from the theory," Zoffi said, "and some doctors in Italy have, some pathologists have confirmed that the spike protein, unfortunately, attacks and destroys also the endocrine system. So the glands producing hormones, and hormones are what make our emotions and feelings and all these things."

Zoffi continued: "And so an Italian pathologist near Venice, he went on a newspaper telling that all the brains he had investigated, he found the pineal gland completely destroyed on all the people who were vaccinated."

"So, the spike protein is also very dangerous for the endocrine system. That's why people have these changes in personality."

Elsewhere during the conversation, Zoffi discussed findings from lab tests showing Augmented NAC (N-Acetylcysteine) was highly effective – up to 99.8% – at helping detoxify spike proteins.
