It’s an extremely important vaccine combination against three different highly contagious life-threatening viral infections in order to help your cats keep protected.

Now, I shall explain how this abbreviated terms derived or what does FVRCP stand for.

This term comes from the name of three different viruses or diseases combining which the vaccine is produced. These are as follows –

Feline Viral Rhinotracheitis (FVR)

The causal agent for this condition is feline herpesvirus 1 or FHV-1 which is considered to be the cause of around 90% of all upper respiratory tract infection (UTI) in cats.

The virus can cause severe inflammation in the trachea, larynx, and inner membrane of nasal passage which are the parts of upper respiratory tract in your cat. This leads to sneezing, runny nose, itching sensation, nasal congestion, and etc.

However, the disease is not so severe in healthy adult cats. The symptoms show often in milder form. The kitten, immunosuppressed cats or older cats are comparatively more susceptible to this virus.

The disease condition can become more complicated due to secondary bacterial infection.

In milder form of disease, the symptoms can disappear within 5-7 days where as in severe form it can last even up to 6 week or longer.

Once recovered from the disease, the virus is not completely eliminated from the cat’s body. The infected cats remain as the carrier of the virus in dormant state.

Now, let’s see the next part of FVRCP.

Feline Calicivirus (FCV)

Here, the ‘C’ from FCV comprises the ‘C’ of FVRCP which stands for calicivirus. The full scientific name is feline calicivirus or VCV. The way how FVR causes disease effect to the cats, FCV works in the similar way to strengthen their combined force to affect.

Symptoms also are almost same as the former one. In addition, there might develop a painful and irritating ulceration on the tongue surface, lips, palate or nose due to the infection caused by FCV. The eyes can also be affected which shows swollen symptom and there might have watery discharge as a common phenomenon.

This is important to note that there are different strains under this virus group. Some strains are milder and some are more sever. The intensity of the disease depends on the types of virus strain affected your cats. Depending on the severity, the disease symptoms can move to some other internal organs causing pneumonia, joint ill, and lameness and so on.

Sometimes, the disease becomes fatal due to infection by more severe strain of the virus.

Now, let’s move toward the next part of the vaccine.

Feline Panleukopenia Virus (FPV)

This is the last disease out three against which this combined vaccine works.

The ‘P’ from FPV makes the last letter ‘P’ of the FVRCP.

The feline panleukopenia is another important and highly contagious virus in this combination that can cause deadly effects in your cats. It’s another name is feline parvovirus. The mortality rate is usually higher for kitten affected with this virus.

Though the disease starts with mild symptoms like loss of appetite or decreased energy, after that the condition progresses towards diarrhea and vomiting.

This virus has a detrimental effect on white blood cell by affecting bone marrow of the cat that ultimately suppresses body immune system. This is how your cat becomes more vulnerable to secondary infection due to infection with this virus.

When should your cats get FVRCP vaccine shot?

In order to get the best possible result, you should start FVRCP vaccine shot for your cat at around 6-8 weeks of age. As the disease is more serious for kitten and mortality rate is usually higher in kitten, you should emphasize more to start vaccination from this age.

After that, a booster shot need to be provided at every three to four weeks interval until 16-20 weeks old.

When your cat will be one year old, another booster should be given. Then continue at every one year interval until expire.

This is how, FVRCP vaccine may protect your cats producing a uniform level of antibody to fight against those microbes.
