You just brought your kitten home, and somewhere between the first vet appointment and the third, you've lost track of which shot is which. That's normal. Most new owners do.
Here's the good news: the schedule follows a predictable pattern, and once you see it laid out, it's easy to follow.
Kittens are born with temporary immunity passed on through their mother's milk, and that protection fades unevenly over the first few months. A vaccine given too early may be neutralized by lingering maternal antibodies before your kitten's immune system has a chance to respond fully.
That's why vets space boosters every three to four weeks instead of giving one dose and calling it done. Each round picks up where the last one left off, until your kitten's own immune system is fully carrying the load.
Your kitten's first vaccine appointment typically happens between 6 and 8 weeks old, and it centers on the FVRCP vaccine. This single shot protects against three serious illnesses: feline panleukopenia, calicivirus, and feline viral rhinotracheitis (caused by feline herpesvirus-1)
At this visit, your vet will also check your kitten's weight, teeth, and general health, and talk through deworming if it hasn't happened yet.
The FVRCP series needs at least two more rounds to build full protection. Expect a second dose around 10 to 12 weeks, and a third around 14 to 16 weeks.
This is also when most kittens get:
If your kitten spends any time outdoors, around other cats, or in a multi-cat household, this is the visit where that risk conversation matters most.
Core vaccines are considered necessary for every kitten regardless of lifestyle, while non-core vaccines depend on individual risk. FVRCP and rabies fall into the core category because the diseases they prevent are common, severe, and in some cases required by law.
FeLV is treated as core for kittens under a year old by many vets, since younger cats are more vulnerable and exposure isn't always predictable early on. FIV, by contrast, is usually reserved for cats with a specific risk of cat bites or outdoor exposure.
A common question that comes up here: do indoor kittens really need all of this? The answer is yes. Some infectious agents can be carried indoors on clothing, shoes, or other objects, and accidental escapes or unexpected exposure to other animals can happen.
Rabies vaccination is also legally required in many areas regardless of lifestyle. Skipping shots because a kitten "won't go outside" is one of the more common gaps in an otherwise complete vaccine record.
Mild tiredness, a small bump at the injection site, or a slightly smaller appetite for a day is common and not a reason to worry. Vaccines work by prompting the immune system to respond, so a little post-shot fatigue is actually a sign it's doing its job.
What isn't normal: repeated vomiting, facial swelling, difficulty breathing, or a kitten who won't perk up after 24 hours. The American Veterinary Medical Association notes that allergic reactions can affect part or all of the body and typically appear soon after vaccination, so these signs warrant same-day attention rather than a wait-and-see approach.
Costs vary depending on your location, your veterinarian, which vaccines are due, and whether the visit includes an examination or other preventive care. Asking for the expected schedule and estimated costs at the first appointment can help you plan ahead.
If you're in the Greater Boston area and researching your options, you can also explore Tandem's vaccination services to learn more about recommended vaccines and review Tandem's services and pricing before scheduling your kitten's first visit.
Around your kitten's first birthday, most core vaccines need a booster to keep protection active. This visit typically also marks the shift from kitten-specific care to annual wellness exams, parasite prevention, and other preventive care based on your cat's age and lifestyle.
If you adopted your kitten with an incomplete shot record, don't panic. A vet can restart or adjust the series based on age and history rather than starting from scratch every time.
If your kitten is due for a shot or you're not sure where they left off, Tandem can help sort it out. We handle the full kitten vaccine series across greater Boston, including Somerville, East Boston, Medford, Quincy Center, and our Cambridge Crossing veterinary clinic, plus catch-up plans for kittens who missed early visits and mobile visits if getting to a clinic isn't easy this week.
