A leading American epidemiologist has warned the public that Covid mRNA “vaccines” are a “chemical lobotomy” that “cause severe brain damage and DEVASTATE mental health.”
The warning was issued by renowned McCullough Foundation epidemiologist Nicolas Hulscher.
Hulscher has been one of the leading voices in raising alarms about the dangers of mNA “vaccination.”
During a new interview with Dr. Drew, Hulscher warned that a major study has confirmed that the mRNA injections have caused multiple neurological disorders to surge.
He explains that the spike protein from the Covid shots is entering the brain and causing inflammation.
This inflammation then causes brain damage in the form of severe cognitive impairment.
Hulscher revealed that cognitive impairment has skyrocketed by a staggering 140% among those who received mRNA jabs.

In a post on X, Hulscher said the mRNA “vaccines are essentially a “chemical lobotomy.”
mRNA “Vaccination” = Chemical Lobotomy
A recent study of 558,017 Koreans (Roh et al) found that mRNA shots increase the risk of:
📈Cognitive impairment: +137.7%
📈Alzheimer’s disease: +22.5% https://t.co/eBY5A4eIWQ pic.twitter.com/dQBvRh2Nbn

The study cited by Hulscher was conducted by a team of South Korean researchers led by Dr. Jee Hoon Roh of the Department of Biomedical Sciences at Korea University College of Medicine in Seoul.



The results of the study were published in the prestigious International Journal of Medicine.
Roh et al’s study of 558,017 Koreans found that mRNA shots increase the risk of cognitive impairment by 137.7%.
The researchers also found that Alzheimer’s disease has surged 22.5% in older Covid-vaxxed adults.
Hulscher has previously raised the alarm about the “catastrophic neurological and psychiatric damage” caused by Covid mRNA injections.
In January, he cited a study by Salmaggi et al.
The study of 8,821,812 Italians found that Covid “vaccination” increased the risk of several serious neurological diseases.
Those serious neurological diseases include:
- Ischemic Stroke: 44% increase
- Cerebral Hemorrhage: 50% increase
- Transient Ischemic Attack (TIA): 67% increase
- Myelitis: 165% increase
- Myasthenia Gravis: 71% increase
The majority of patients hospitalized for neurological diseases in 2021 received at least 1 vaccine dose:
