Vaccinations

How Do Pet Vaccines Work?
Vaccines are actually made from the very disease they protect against. A small amount of the virus or bacteria is chemically altered so that it stimulates the body’s immune system without actually making your pet sick. Antibodies will react to the vaccine’s altered virus and will remember their response. In the future, if your pet comes in contact with the virus, their immune system will react immediately to suppress the virus causing little to no symptoms.
Sticking to a Vaccine Schedule
In time, cat and dog vaccines lose their efficacy and your pet’s immunity weakens. That’s why regular boosters are an important part of your pet’s routine wellness care. Different vaccines, however, are on different schedules. Additionally, not all pets need all vaccines—while some are required (called core vaccines), others are only recommended depending on your pet’s level of risk (noncore vaccines). We’ll design an individual vaccine plan for your pet based on their needs.
