Summary
A German shepherd puppy experienced hindquarter weakness following a multivalent vaccine, suggesting post-vaccinal polyradiculoneuritis. This rare adverse drug reaction may be under-reported in veterinary medicine.
Area of Science:
- Veterinary Neurology
- Immunology
Background:
- Polyradiculoneuritis is an inflammatory condition affecting peripheral nerves.
- Vaccinations can occasionally trigger immune-mediated adverse events in animals.
Observation:
- A 4-month-old German shepherd presented with progressive hindquarter weakness.
- The onset of weakness occurred shortly after administration of a multivalent vaccine.
Findings:
- The clinical signs are highly suggestive of post-vaccinal polyradiculoneuritis.
- This represents a rare suspected adverse drug reaction to vaccination.
Implications:
- Highlights the importance of monitoring for and reporting suspected adverse drug reactions post-vaccination.
- May prompt further investigation into the immunopathogenesis of vaccine-induced polyradiculoneuritis in dogs.
- Emphasizes the need for vigilance in veterinary pharmacovigilance.

01:20Chickenpox
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,...
01:17Poliomyelitis
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...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
