Core vaccines (rabies, distemper, parvovirus) are required by law in many states. Non‑core vaccines (Lyme, leptospirosis, kennel cough) are recommended based on lifestyle. The US veterinary medicine market research shows that vaccines are the fastest‑growing product segment, with a CAGR above 7%. Why? Because pet owners are more aware of preventable diseases, and vaccine hesitancy (in humans) hasn't spilled over to pets — yet.
What's new? Recombinant vaccines (modified live virus without the risk) and oral vaccines (no needles). The US veterinary medicine market trends highlight that the fastest‑growing distribution channel is online pharmacies — owners can order vaccines and administer them at home (though many vets discourage this, due to improper storage or technique).
But over‑vaccination is a concern. Some vets now offer titer testing (measuring antibody levels) to see if a booster is really needed. That's especially important for elderly pets or those with immune issues.
The bottom line: vaccines save lives, but not every pet needs every vaccine every year. Talk to your vet about a customised schedule.
