@Duke:
For Distemper and Parvo, plasma cells produce antibodies and program memory cells that persist for life. I sensed they are convinced.
This is what studies are beginning to show. That after the 1 year booster shot immunity in most dogs is probably lifetime though the current recommendation by vet schools and vets is to vaccinate every 3-5 years unless you are doing titers.
@Duke:
For Bordetella in dogs, an injectable vaccine does not provide mucosal immunity. An intranasal vaccine is now available. BUT they do not indicate if it's a lifetime immunity like for Distemper and Parvo. (I might assume that it is if it creates immunity.) Then they say it doesn't protect from infection, but would provide a lesser degree of symptoms. So I'm confused about how often this vaccine should be administered.
Bordatella gives a maximum of 3-4 months of protection. It is usually recommended that you give it if you are going to board your dog.
@Duke:
For Corona, they say adult dogs do not get disease from the Corona virus. So they don't need that vaccine once they're adults? Again - confused
My vet has never even suggested I vaccinate against this virus and I have never vaccinated against it.
If Daisy is turning 1 year old this year then I would do the DHLPP minus the L for lepto 2 -3 weeks apart from the Rabies vaccine and have the heartworm test done. I never give two shots on the same day because if there is a reaction, I want to know what caused it.
