Cat Vaccinations: Ensuring Your Cat’s Health Preventative Vaccines
As a responsible cat owner, one of the most important aspects of your cat's health is ensuring they receive the proper vaccinations. Vaccines play a vital role in preventing infectious diseases that can be serious or even life-threatening to cats. By adhering to vaccination guidelines, you can safeguard your cat’s health while also preventing the spread of certain diseases to other animals.
1. Why Are Cat Vaccinations Important?
Vaccinations are a fundamental part of feline healthcare and help to prevent a range of infectious diseases that can affect your cat’s overall health and quality of life. These vaccines work by stimulating the immune system to recognize and fight off pathogens without causing the disease itself. Without proper vaccination, your cat could be at risk for a variety of preventable illnesses, many of which can be severe or fatal.
Vaccinations not only protect individual cats but also help to reduce the spread of diseases in the broader pet population, including shelters and communities. In particular, vaccination programs are essential for controlling contagious diseases like feline panleukopenia (also known as feline distemper), feline herpesvirus, and feline leukemia virus (FeLV).
2. FelineVMA Guidelines for Cat Vaccinations
The FelineVMA (Feline Veterinary Medical Association) guidelines provide a comprehensive framework for the vaccination of cats based on their age, health status, and lifestyle. These guidelines are set by a group of leading veterinary professionals and organizations and are widely recognized for promoting the best practices in feline vaccination.
The FelineVMA guidelines categorize vaccinations into two groups:
1. Core Vaccines: These vaccines are considered essential for all cats, regardless of their lifestyle, and are recommended to protect them from the most common and severe diseases. Core vaccines include:
○ Feline Herpesvirus Type 1 (FHV-1): A virus that causes upper respiratory issues, including conjunctivitis and nasal discharge. It is one of the primary causes of the feline respiratory disease complex.
○ Feline Calicivirus (FCV): A virus that also contributes to upper respiratory infections and oral diseases, including ulcers in the mouth.
○ Feline Panleukopenia Virus (FPV): Also known as feline distemper, it is a highly contagious virus that attacks the immune system and can cause severe gastrointestinal distress, vomiting, and death.
○ Rabies: Rabies vaccination is legally required in many areas and is crucial for preventing the spread of this fatal disease, which can be transmitted from animals to humans.
2. Non-Core (Optional) Vaccines: These vaccines are recommended based on specific risk factors, such as your cat’s lifestyle (indoor vs. outdoor), health, and geographic location. Some non-core vaccines include:
○ Feline Leukemia Virus (FeLV): This vaccine is especially important for cats that are at higher risk of exposure to FeLV, such as outdoor or multi-cat household cats. FeLV can cause immune suppression and is often fatal.
○ Chlamydia felis: A bacterium that can cause conjunctivitis and upper respiratory infections, particularly in multi-cat environments.
○ Bordetella bronchiseptica: A bacterium that causes respiratory issues in cats, especially in environments with high-density cat populations, such as shelters.
The FelineVMA guidelines emphasize the importance of tailoring vaccination schedules to each individual cat’s needs, taking into consideration their age, exposure risks, and underlying health conditions.
3. purevax vaccines: a leading option for feline health
Purevax vaccines are a line of feline vaccines developed by Merial (now part of Boehringer Ingelheim) to provide advanced protection for cats against common infectious diseases. Purevax vaccines are designed to offer a combination of effective immunity with fewer adverse reactions compared to some traditional vaccines. This is due to the fact that Purevax vaccines are modified-live or recombinant vaccines, meaning they are formulated in such a way to reduce the likelihood of side effects while still offering robust protection.
Benefits of Purevax Vaccines:
1. Reduced Risk of Adverse Reactions: One of the primary benefits of Purevax vaccines is the reduced risk of adverse reactions. Cats, especially those with sensitivities, can sometimes experience reactions to traditional vaccines, such as lethargy, fever, or more severe symptoms. Purevax vaccines, due to their advanced formulation, are designed to minimize these risks while still providing high levels of immunity.
2. Fewer Injections: In some cases, Purevax vaccines combine multiple protections in a single injection, reducing the number of visits and the overall stress on your cat. This is particularly helpful for kittens or adult cats that may find multiple injections overwhelming.
3. Longer Duration of Immunity: Many Purevax vaccines are designed to offer extended protection, meaning fewer booster shots are required. This can reduce the overall stress on your cat and minimize the frequency of vet visits for vaccinations.
4. Safety in Special Populations: Purevax vaccines are often considered safer for certain groups of cats, such as those with compromised immune systems or older cats, due to their more targeted approach to vaccination.
5. Non-Adjuvented Vaccines: Merial Purevax vaccines are known to be the only complete line of non-adjuvented vaccines. See below for the importance of non-adjuvented vaccines in cats.
Common Purevax Vaccines:
● Purevax Feline Rabies: This is a rabies vaccine designed to provide effective protection against rabies while reducing the risk of adverse reactions. It’s important to note that rabies vaccines are legally required in many areas for cats and can help prevent the spread of the disease to humans and other animals.
● Purevax Feline Upper Respiratory Combination (FVRCP): This vaccine combines protection against feline herpesvirus, calicivirus, and panleukopenia, offering comprehensive protection against the three most common upper respiratory and gastrointestinal diseases in cats.
● Purevax Feline Leukemia: This vaccine protects against feline leukemia virus (FeLV), a potentially fatal disease transmitted through direct contact between cats. FeLV is highly contagious, and vaccinating high-risk cats is essential, particularly for outdoor or multi-cat household cats.
4. when to vaccinate your cat
Vaccination schedules for kittens typically begin at 6 to 8 weeks of age, with booster shots given every 3 to 4 weeks until they are about 16 weeks old. After the initial series of vaccinations, adult cats generally require booster vaccines every 1 to 3 years, depending on the type of vaccine and the cat’s lifestyle.
Cats that are particularly at risk for certain diseases (such as FeLV or rabies) may require more frequent vaccinations or additional vaccines based on geographic location and exposure risks.
5. post vaccination care
After vaccination, most cats experience only mild, temporary side effects such as slight swelling at the injection site or mild lethargy. These side effects usually resolve within a day or two. If you notice more severe reactions, such as difficulty breathing, vomiting, or swelling beyond the injection site, contact us immediately.
It’s also important to continue monitoring your cat’s behavior and health after vaccinations to ensure they are recovering well. Keep in mind that vaccines may take a few days to trigger a full immune response, and full immunity will not be established immediately after the first dose.
6. What is Feline Injection Site Sarcoma (FISS)?
Feline injection site sarcoma (FISS) is an aggressive cancerous growth that forms at the site of an injection, usually a vaccine, antibiotic, or other injectable medication. It is most commonly seen in cats, and while it is a rare occurrence, it is a serious condition because of its potential to grow quickly, spread to other areas of the body, and be difficult to treat.
FISS tumors are fibrosarcomas, which are cancers that arise from fibrous tissue, including connective tissues like tendons and ligaments. The tumors are typically firm, raised masses that may be felt under the skin at the injection site. They are often slow to develop, with the first signs sometimes appearing months after the injection.
7. How Are Adjuvanted Vaccines Linked to FISS?
Adjuvants are substances added to some vaccines to enhance the immune response. They help the body produce a stronger and longer-lasting immunity to the disease targeted by the vaccine. While adjuvants have been successful in boosting vaccine effectiveness, they can sometimes cause an undesirable reaction at the site of injection.
When an adjuvanted vaccine is administered, the adjuvant can cause chronic inflammation at the injection site. This inflammation, in some cases, can lead to abnormal cell growth and the development of tumors. FISS is thought to be a result of this chronic inflammation stimulating the abnormal growth of cells in the tissue surrounding the injection site, which eventually forms a sarcoma.
The development of FISS is believed to be a multifactorial process, where the inflammatory response triggered by the adjuvant plays a central role. Additionally, cats with certain genetic predispositions or immune system responses may be more likely to develop sarcomas.
8. What Vaccines Are Linked to FISS?
FISS is most commonly associated with vaccines that contain adjuvants, particularly rabies and FeLV (feline leukemia virus) vaccines. These vaccines are essential for preventing serious diseases in cats, but the inclusion of adjuvants in some formulations can increase the risk of injection site sarcomas.
The rabies vaccine has a particularly high association with FISS, given its widespread use and mandatory status in many regions. However, it is important to note that not all rabies vaccines contain adjuvants. There are non-adjuvanted alternatives available that are associated with a significantly lower risk of causing FISS.
Other vaccines, such as the FeLV vaccine, may also be linked to FISS when they contain adjuvants. While these vaccines are highly effective in preventing serious diseases, they have been identified as a potential risk factor for sarcomas.

9. Signs and Symptoms of FISS
FISS can develop gradually, and in its early stages, it may not be immediately noticeable. However, there are several signs that may indicate the presence of a tumor at the site of an injection:
● Lump or swelling: A firm, raised mass that is felt under the skin at the injection site is often the first sign. This mass may grow over time.
● Pain or discomfort: The area around the lump may be painful to the touch, and the cat may exhibit signs of discomfort, such as limping or avoiding movement.
● Skin changes: The skin around the injection site may become reddened or warm to the touch, indicating inflammation.
● Slow growth: Tumors associated with FISS tend to grow slowly over time, and it may take several months or even years before the tumor is large enough to notice.
If you notice any unusual swelling or changes in your cat's skin after an injection, it is important to schedule a consultation as soon as possible. Early detection and diagnosis are key to managing the condition effectively.
10. preventing fiss: alternatives to adjuvanted vaccines
The risk of FISS associated with adjuvanted vaccines has led to changes in vaccination practices. Many veterinarians now recommend non-adjuvanted vaccines when available, particularly for rabies and FeLV vaccines, as these vaccines are less likely to cause inflammation and tumor development.
In addition to choosing non-adjuvanted vaccines, pet owners can also take the following precautions:
-
Vaccine Location: We always administer vaccines in specific areas of your cat's body where the risk of developing a sarcoma is lower. The hind limb is typically recommended for rabies and FeLV vaccines because it allows for easier identification and removal of tumors if they develop.
-
Regular Monitoring: After each vaccine injection, monitor the injection site for any signs of swelling, lumps, or changes in the skin. Report any unusual findings to us promptly.
-
Use of Adjuvant-Free Vaccines: When possible, choose vaccines that do not contain adjuvants. Many manufacturers now offer adjuvant-free formulations of core vaccines, including rabies and FeLV vaccines.
