CNS demyelination and quadrivalent HPV vaccination
1Department of Neurology, St Vincent's Hospital, Darlinghurst, New South Wales, Australia.
Summary
The human papillomavirus (HPV) vaccine, Gardasil, was associated with demyelinating syndromes in five patients. Further research is needed to confirm if the vaccine triggers these neurological events in susceptible individuals.
Area of Science:
- Neurology
- Immunology
- Vaccinology
Background:
- Multiple sclerosis (MS) is an autoimmune neurological disease affecting myelin.
- Vaccination is generally considered safe for patients with MS.
- The human papillomavirus (HPV) vaccine (Gardasil) is widely administered to young females.
Purpose of the Study:
- To report cases of demyelinating syndromes temporally associated with Gardasil vaccination.
- To investigate the potential link between HPV vaccination and neurological events in susceptible individuals.
Main Methods:
- Retrospective case series of five patients.
- Analysis of clinical presentations and temporal relationship to Gardasil immunization.
Main Results:
- Five patients developed multifocal or atypical demyelinating syndromes within 21 days of receiving the Gardasil vaccine.
- The observed events occurred in the demographic group with an inherently higher risk for MS.
Conclusions:
- The temporal association suggests a potential link between Gardasil vaccination and demyelinating syndromes.
- The immuno-stimulatory properties of HPV virus-like particles may contribute to these events.
- Further prospective studies are warranted to establish causality and safety in MS patients.

Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Overview
Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
