COVID-19 immunizations have unequivocally shielded individuals from dire outcomes such as hospitalizations, severe complications, and mortality. However, their influence on the enduring enigma of long COVID has remained elusive.
A study disseminated through Brain Communications revealed that inoculation preceding COVID-19 infection exerts negligible influence on neurological symptoms in individuals grappling with long-term COVID.
This finding encompasses both those who endured severe infections necessitating hospitalization and individuals with milder afflictions who evaded hospitalization. Neurological manifestations commonly reported by long COVID sufferers include cognitive haze, paresthesia, cephalalgia, vertigo, olfactory and gustatory impairments, and profound exhaustion, according to news.nm.org.
New research finds COVID-19 vaccination prior to infection does not affect the neurological symptoms of long COVID.

Dr. Igor Koralnik, a venerated authority in neuroinfectious diseases and global neurology at Northwestern Medicine, oversees the Neuro COVID-19 Clinic and co-directs the Northwestern Medicine Comprehensive COVID-19 Center.
Reflecting on these findings, Dr. Koralnik stated, “Given the capacity of COVID-19 vaccines to attenuate the acuteness of infections, we postulated that they might similarly mitigate the neurological ramifications of subsequent long COVID. Our endeavor was to elucidate whether pre-infection vaccination modulates neurological symptoms, quality of life, or cognitive acuity in our patients. The revelations are disheartening, indicating that pre-infection vaccination does not alleviate the neurological burden of long COVID,” as per news.nm.org.
Salient Findings of the Study
- This pivotal investigation evaluated the inaugural 1,300 patients presenting with neurological long COVID symptoms at the Northwestern Medicine Neuro COVID-19 Clinic from May 2020 through March 2023.
- Among these participants, 200 had endured severe COVID-19 requiring hospitalization, whereas the remainder experienced mild initial symptoms and were not hospitalized.
- This study represents a pioneering exploration within Northwestern Medicine into the interplay between pre-infection vaccination and neurological symptoms of long COVID.
- Employing rigorous quantitative analyses, researchers discerned substantial impairments in quality of life across domains such as cognition, fatigue, sleep, anxiety, and depression, with no discernible disparities between the pre-vaccination and post-breakthrough infection cohorts, as reported by news.nm.org.
- Cognitive assessments revealed a significant decrement in performance across a spectrum of cognitive evaluations relative to the general populace, irrespective of vaccination timing.
Dr. Koralnik emphasized, “Long COVID constitutes a profoundly incapacitating syndrome, exerting multifaceted repercussions across organ systems and substantially undermining an individual’s functional capacity and quality of life. In light of the revelation that pre-infection vaccination fails to diminish the neurological encumbrances of long COVID, it becomes imperative to prioritize the safeguarding of communities against both acute COVID-19 infection and its protracted neurological sequelae.”
