Animals, vaccines, and COVID-19

Area of Science:

• Veterinary Medicine
• Epidemiology
• One Health

Background:

• The COVID-19 pandemic highlights the significant role of animals, particularly mammals, in disease emergence and spread.
• Zoonotic diseases, like COVID-19, demonstrate the interconnectedness of human and animal health.
• Animals have historically been vital in medical advancements, including vaccine development.

Purpose of the Study:

• To emphasize the critical role of animals in the COVID-19 pandemic.
• To underscore the bidirectional transmission of SARS-CoV-2 between humans and animals.
• To advocate for an interdisciplinary medical approach integrating human and animal health.

Main Methods:

• Review of existing literature on animal involvement in COVID-19.
• Analysis of zoonotic disease transmission patterns.
• Historical perspective on animal use in vaccine research.

Main Results:

• COVID-19 originated in animals, with ongoing transmission between animal and human populations.
• Animals have been instrumental in the research and development of COVID-19 vaccines.
• The pandemic underscores the need to study human-animal interfaces for disease control.

Conclusions:

• An interdisciplinary, One Health approach is essential for managing zoonotic diseases.
• Continued research into animal-human disease dynamics is critical for pandemic preparedness.
• Integrating veterinary and human medicine is vital for global health security.
