Vaccine skepticism not only has the potential to harm human health, but it could also spillover to impact pet health, if non-vaccination becomes more common for both humans and pets.
Recent headlines have been dominated by discussions about the resurgence of measles in the United States. This disease, once considered eradicated, has made an unwelcome return. Although the number of cases remains relatively small, these outbreaks have prompted medical professionals to scrutinize vaccination rates in the affected communities and investigate the factors contributing to this resurgence.
One of the primary culprits identified is low vaccination rates, fueled by vaccine skepticism. The rise of vaccine hesitancy, particularly during the COVID-19 pandemic, has led to broader concerns about Americans avoiding all vaccines, not just those targeting COVID-19.
This trend in human healthcare has also impacted the pet health market. A 2023 study by the Boston University School of Public Health revealed that over half (53%) of pet owners expressed skepticism about vaccinating their pets, citing concerns about safety and efficacy. Among dog owners surveyed, 40% believed canine vaccines were unsafe, 30% deemed them medically unnecessary, and over 20% considered them ineffective.
Researchers have noted a “vaccine spillover” effect, where individuals project their negative opinions about human vaccines onto those for their pets. Alarmingly, 37% of pet owners even attributed canine vaccination to autism in their pets, despite a lack of scientific evidence supporting this claim.
This hesitancy has serious implications for pet ownership. If non-vaccination becomes more common, both pets and their owners face an increased risk of contracting preventable diseases, some of which can be life-threatening. Additionally, annual vaccinations are a major impetus for veterinary visits, when vets have the opportunity to discuss other necessary preventative practices with pet owners, including heartworm prevention. Packaged Facts survey data from November 2024 shows that the most common reason pet owners do not give their pets medications is the belief that medications are unnecessary for pet health, with a 68% agreement level. Combine this belief with a lack of trust in vaccines, and the pet market is ripe for an increase in a range of preventable diseases.
The resurgence of measles in the US serves as a stark reminder of the importance of vaccination. As vaccine skepticism grows, it not only threatens human health but also extends its impact to our beloved pets. Ensuring high vaccination rates is crucial to protecting both human and animal populations from preventable diseases.
