DA2PPC vaccine
DA2PP, is a multivalent vaccine for dogs that protects against the viruses indicated by the alphanumeric characters forming the acronym: D for canine distemper, A2 for canine adenovirus type 2, which offers cross-protection to canine adenovirus type 1 (the more pathogenic of the two strains) (see Canine adenovirus), the first P for canine parvovirus, and the second P for parainfluenza. Because infectious canine hepatitis is another name for canine adenovirus type 1, an H is sometimes used instead of A. In DA2PPC, the C indicates canine coronavirus.
This vaccine is usually given to puppies at 8 weeks of age, followed by 12 weeks of age, and then 16 weeks of age. This vaccine is given again at 1 year of age and then annually, or every 3 years. Some veterinarians' recommended vaccine schedules may differ from this.
DA2PPC does not include Bordetella. But the combination of Bordetella with DA2PPC prevents kennel cough, by preventing adenovirus, distemper, parainfluenza, and Bordetella.
For distemper
While the DA2PPC vaccine also protects against parainfluenza, parvovirus, adenovirus, and canine coronavirus, it most importantly protects against the debilitating and deadly disease canine distemper, an often fatal viral illness that causes neurologic dysfunction, pneumonia, nonspecific systemic symptoms such as fever and fatigue, and weight loss, as well as upper respiratory symptoms and diarrhea, poor appetite, and vomiting. There is no antiviral drug effective against the canine distemper virus. Treatment is supportive and consists of antibiotics to prevent secondary infections, anticonvulsants for seizures, and intravenus fluids to prevent dehydration. Given the lethality of distemper and the relative rarity of side effects from the vaccine, all reputable veterinarians recommend the DA2PPC vaccine. Also, even if the dog owner is not concerned about adenovirus, coronavirus, parvovirus, or parainfluenza, they should vaccinate their dogs to protect them against distemper.
DHPP, DAPP, DA2PP, and DAPPC are not the same. The names are often used interchangeably but they are different. Distemper, adenovirus type 1 (thus hepatitis), parainfluenza, and parvovirus are covered by all 4. DHPP covers adenovirus type 1 and may or may not cover adenovirus type 2. And only DAPPC covers coronavirus.
DAPP or DA2PP are the most commonly used. Coronavirus has not been proven to cause any significant disease in dogs so it is a useless vaccine.
