Pet Vaccinations are Essential for a Long and Healthy Life

At Leesburg Veterinary Hospital, we realize that vaccines can be a tricky subject. There are plenty of questions regarding what pet vaccinations do, how often your pet needs them, and if they’re even a necessity at all (they are!). At LVH, we're here to clear things up. It’s important to remember that not all vaccines are required for every pet. We customize a personal vaccine plan for each individual based on their unique needs.

Is Your Pet Due for a Vaccine Booster?

How Do 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, 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.

Best vet in Loudoun! The staff here are just outstanding! Every doctor here is super knowledgeable and caring toward your pet. I was invited in the back on one of my visits and they keep the hospital immaculate. I would never go anywhere else!

My animals have been going to see Dr. Melburger for many years. The staff is also amazing. You can tell that they truly love animals as well and it’s not just a job for them. I would recommend this office to anyone.

I cannot say enough kind words about this place. Leesburg Veterinarian has a lifetime client here. Thank you again!

The entire team at LVH works hard to provide excellent care to my pets. Dr. Strickland and his team have been there for my pets for 20 years; from adoption to end of life. I highly recommend them.

I absolutely love Leesburg Veterinary Hospital. It is more than worth it for me to drive the 30 minutes to get there. Thank you guys soooo very much. You are phenomenal!

We just had our first happy visit and it was the most wonderful experience. The staff made us feel so welcome and just let us sit on floor and wander around. They truly care about their patients and about making them feel comfortable. I have recommend them to all of my friends for their animals and they are all as equally impressed as I am.

Visited Leesburg veterinary hospital when I wanted a second opinion and access to better technology. I am grateful for the peace of mind and although it is a bit of a drive I think I will be returning for regular care. Can't say thanks enough!

The staff and doctors were awesome and treated us with the upmost respect. They treat your pets like family and have all the concerns to treat them in a safe and healthy manor. Dr. Henly was Awesome!!!

I have been taking all my animals to the Leesburg Vet Hospital for forever!! I absolutely recommend them to ANYONE looking for a new vet!
