Findings from a 2023 survey study conducted by researchers at Texas A&M University School of Public Health and published in the journal Vaccine has provided evidence there is a correlation between the attitudes of people toward human vaccines and pet vaccines. They found that people concerned about the safety, effectiveness and necessity of human vaccines are also concerned about pet vaccines, and that concern is a strong predictor of whether pet owners will choose to get their pets vaccinated.1
The study analyzed data from an August 2023 survey of more than 2,000 dog owners and more than 1,400 cat owners to evaluate pet vaccination rates, attitudes towards vaccination, and support for pet vaccination requirements.2
Respondents were asked if they owned a dog, a cat, or both. Dog and cat owners were also asked about their pets’ vaccine status for three diseases that affect dogs and three diseases that affect cats, which
included rabies vaccine for dogs and cats, canine parvovirus and canine distemper vaccines for dogs, and feline panleukopenia and feline Bordetella bronchiseptica vaccines for cats, which is related to B. pertussis (whooping cough) in humans. The respondents were then asked to rate their support for vaccination requirements for each of the listed diseases.3Survey Questions Respondents About Trust in Scientists and Vaccine Mandates
In addition to the questions about pet vaccines, respondents were also asked about their level of trust in scientists, support for vaccine mandates for children, political ideology, religious beliefs, non-veterinary expenses and frequency of exposure of their dogs to other dogs outside of their home. The respondents were also asked about their perceptions of safety, efficacy and importance of human vaccines.
The results of the study highlighted that a majority of pet owners had vaccinated their dogs and cats against rabies, although cats were vaccinated less often than dogs. Other core vaccines (vaccines recommended for all pets regardless of lifestyle) had slightly lower rates, but generally still had a high overall uptake. Pet owners had the highest vaccine hesitancy for non-core vaccines.4
Hesitancy for Human Vaccines Spills Over to Hesitancy for Pet Vaccines
In the last decade, surveys show that a growing number of Americans are choosing to opt out of getting vaccinated, especially over the past three years following declaration of a COVID-19 pandemic and promotion of COVID shots. However, research investigating pet vaccine hesitancy has been very limited.
The researchers of the 2023 survey study hypothesized that there are good reasons to believe that there is “spillover,” which causes individuals, who are skeptical of human vaccines, to transfer their concerns to pet vaccines. Researchers define “spillovers”as situations where behavioral or attitude changes with regard to one concept exert influence on attitudes or behavior in a related concept.5
The positive correlation between vaccine hesitancy for human vaccines and pet vaccines suggests the potential for spillover effects, but vaccine hesitancy for pets is not as high as it is with human vaccination. This is particularly true for parents hesitating to give their children vaccines like annual flu and COVID shots, which fall outside of the “core” vaccines recommended for children, such as tetanus, pertussis, polio and measles vaccines.6 7
