Area of Science:

• Veterinary Medicine
• Immunology
• Public Health

Background:

• Concerns regarding adverse reactions to companion animal vaccines have increased.
• Reported adverse events include inflammatory, allergic, autoimmune, and neoplastic diseases, alongside efficacy issues.

Purpose of the Study:

• To evaluate the prevalence and impact of adverse reactions associated with companion animal vaccination.
• To address public and veterinary concerns regarding vaccine safety in pets.

Main Methods:

• Review of available data and scientific literature on companion animal vaccination adverse events.
• Analysis of reported cases and epidemiological trends.

Main Results:

• The overall prevalence of true adverse reactions to companion animal vaccines is very low.
• Vaccination does not significantly contribute to overall ill-health in companion animals.
• Reduced vaccination uptake can lead to disease re-emergence.

Conclusions:

• Vaccination remains a critical and safe procedure for infectious disease control in companion animals.
• New recommendations and product developments aim to further minimize risks and reduce vaccine load.
• Maintaining high vaccination rates is essential for both animal and public health.
