Should I Vaccinate My Pet? Ask the Holistic Vet
Dr. Marcie Fallek on informed consent, risk and rethinking routine pet care

As more pet owners begin questioning routine medical practices, one topic continues to spark debate: vaccines.
For Dr. Marcie Fallek, a holistic veterinarian and author of Little Miracles Everywhere, the conversation isn’t just about whether to vaccinate — it’s about informed consent, individualized care and understanding risk.
“Your allegiance is to your pet, not your vet,” she says.
A Conversation Many Pet Owners Are Afraid to Have
For many, raising concerns about vaccines in the exam room can feel uncomfortable. Pet owners often worry about being dismissed — or even dropped — by their veterinarian.
Dr. Fallek encourages a different approach: come prepared, stay calm and ask questions.
Whether the concern is repeat injections, multiple shots at once, or vaccinating a sick animal, she advises starting with an open dialogue. Ask your veterinarian to provide evidence supporting claims that vaccines are “safe and effective,” and be willing to share your own experiences or research.
At the same time, she cautions that many veterinarians are trained within a system that does not prioritize these questions.
If the response is dismissive, she says, it may be time to reconsider the relationship.
Dr. Fallek believes many pet owners already sense when something doesn’t feel right.
In her view, that instinct matters.
“If something doesn’t feel right, it probably isn’t.”
Rather than defaulting to routine schedules, she encourages pet owners to think critically, especially when it comes to repeat interventions over an animal’s lifetime.
Measuring Immunity Instead of Repeating Injections
One alternative to routine boosters is titer testing, which measures antibodies in the blood.
But not all titers are the same.
Dr. Fallek emphasizes the importance of end-point titers, which quantify antibody levels and may indicate long-term protection. By contrast, standard vaccine titers only confirm whether antibodies are present — offering little insight into how long immunity may last.
This distinction, she says, can make a significant difference in avoiding unnecessary repeat injections.
Puppies receive maternal antibodies through their mother’s milk, which typically decline between 12 and 16 weeks.
According to Dr. Fallek, vaccinating too early can be ineffective if those maternal antibodies neutralize the injection — potentially leading to additional doses.
She suggests that, for those who choose to vaccinate, delaying core vaccines like parvo and distemper until around 16 weeks may offer longer-lasting immunity.
But that decision comes with trade-offs.
During the window when maternal antibodies are fading, puppies may be more vulnerable — making risk assessment a key part of the decision.
A Minimalist Approach to “Core” Vaccines
Rather than following broad vaccination schedules, Dr. Fallek advocates for a more limited approach.
In her practice, this typically includes only core vaccines: parvovirus, distemper and rabies.
Even then, she recommends spacing injections apart and avoiding combinations whenever possible.
“More antigens create more problems,” she says.
Rabies vaccination is mandated in most jurisdictions, creating a tension between legal requirements and individualized care.
Dr. Fallek questions both the timing and frequency of these injections, particularly in young animals. She notes that earlier administration may carry greater risk, while later administration may offer longer-lasting immunity. At the same time, exemptions are difficult to obtain, and many veterinarians are reluctant to issue them.
Combination shots and multi-dose appointments may be convenient, but Dr. Fallek sees them as problematic.
Her recommendation is simple: one vaccine at a time, spaced at least two weeks apart.
She also advises against vaccinating animals that are sick or under anesthesia, when the body may not respond appropriately.
Looking Beyond Vaccines
In her clinical experience, Dr. Fallek has observed that many chronic conditions appear shortly after vaccination — often within a six-week window.
She points to patterns such as neurological symptoms, digestive issues and autoimmune conditions. For pet owners, she says, the timeline matters. Tracking changes in behavior or health following any medical intervention can provide important clues.
The conversation doesn’t end with vaccines.
Dr. Fallek also urges caution with routine flea, tick and heartworm medications, noting that these products are designed to kill living organisms — and therefore carry inherent toxicity. Instead, she recommends assessing actual exposure risk.
An indoor cat or a dog with limited outdoor exposure may not require the same level of intervention as an animal in a high-risk environment.
Nutrition, she says, is one of the most powerful tools pet owners have. Dr. Fallek recommends choosing foods made with recognizable, human-grade ingredients and avoiding vague labels like “meat by-products.”
While raw or minimally processed diets may be more expensive, she argues that investing in food can reduce long-term health issues — and veterinary costs.
A Shift Toward Informed Pet Care
For pet owners who choose a different path, challenges remain. Boarding facilities often require full vaccination, and some veterinary practices may refuse unvaccinated clients. Dr. Fallek suggests looking for alternatives, including in-home pet care or smaller providers with more flexible policies.
At its core, Dr. Fallek’s message is about moving away from one-size-fits-all medicine.
Pet owners, she says, should feel empowered to ask questions, weigh risks and benefits, and make decisions based on their individual animal — not just standard protocols.
In a system built on routine, that shift may not always be easy. But for many, it’s a necessary step toward protecting the long-term health of the animals in their care.
