You can use this link to ensure you're eligible for the PDSA's services and what clinic is closest to you (https://www.pdsa.org.uk/taking-care-of-your-pet/eligibility). The PDSA is currently working on an emergency basis only due to Covid-19 so there may be a waiting list for getting Pumpkin vaccinated.
The PDSA doesn't publish their prices for preventative care, however, it would most likely be a similar cost to other charitable organizations; £15-30 range.
Private practice costs will range between £50-70 for a primary course for kittens depending on what part of the UK you're in. Annual boosters tend to be £30-40 afterward.
In the UK, we vaccinate against cat flu, panleucopaenia, chlamydia, and feline leukemia. These are all illnesses that are severe with no specific treatment and can be fatal. Similar to the flu in humans, they can also be quite contagious.
Cat flu - severe flu.
Panleucopaenia - infectious inflammation of a cat's intestines and depression of white blood cells causing severe illness and even permanent damage. Incurable.
Chlamydia - Bacterial infection that affects eyes, nose, lungs, stomach, intestines, and reproductive tract. Highly contagious, treatable but severe illness.
Feline Leukaemia (FeLV) - a viral infection that can lead to cancers developing including lymphoma and leukaemia, etc. Incurable.
The vaccine protocol is two injections 2-4 weeks apart followed by annual boosters. Pumpkin won't require ALL components each year but will need a booster of some components of the vaccines each year.
