Does vaccination increase dogs' risk of developing immune-mediated haemolytic anaemia?

March J, Brennan M · The Veterinary record · 14 February 2026

Clinical bottom line

Examine vaccination timing when evaluating dogs presenting with hemolytic anemia.

Summary

This research article investigates the potential association between canine vaccination and the development of immune-mediated hemolytic anemia (IMHA). The authors conducted an analysis to determine whether vaccinated dogs have an increased risk of developing this serious condition compared to unvaccinated dogs. IMHA is an autoimmune disorder where the dog's immune system attacks its own red blood cells, leading to hemolysis and potentially life-threatening anemia. Understanding vaccination safety profiles is critical for veterinary practitioners making clinical decisions. The study examines epidemiological data to assess temporal relationships between vaccination administration and IMHA onset. This research addresses an important concern raised in veterinary medicine regarding potential adverse effects of routine immunizations. The findings contribute to the evidence base regarding vaccine safety in canine populations and may influence vaccination protocols and client counseling practices.
