There is actually an FIP vaccine available, that can be given after 16 weeks of age, however many vets have differing strong opinions on the usefulness of this vaccine. I for one, do not give it. The vaccine is a modified-live, and there is not enough proof of it giving immunity. I have done some research into FIP, but there is varying opinions, as there still isn't much understood with FIP. The only way to be positive the cat died from FIP is with a tissue biopsy or necropsy. Although vets can make an educated diagnosis just by symptoms. There are 2 different types, wet (effusive) FIP and dry (non-effusive) FIP.
Testing for the corona virus is for the most part inaffective, as most cats have been affected with the corona virus.
There has been a lot of research done, and it couldn't be done without people like Kluchetta, helping by donating money. If you would like to help the Winn Feline Foundation has done amazing things.
By research, they have found that genetics may play a large role in the immunity and resistance to FIP.
My research has been through reading a book by Neils Pederson and through information given by Dr. Susan Little.
