There are 3 vaccines commonly known as “core” vaccinations to protect your dog and 2 for cats.
Dogs
The C3 vaccine protects against parvovirus, distemper, and hepatitis. The C4 vaccine also protects against parainfluenza, while C5 protects against all the above as well as Bordetella bacteria.
Generally, the C3 vaccine is given to your puppy at 6 to 8 weeks of age, all other future vaccinations will be C5.
Cats
The F3 vaccine protects your cat against both enteritis and cat flu (rhinotracheitis and calicivirus). The FIV vaccine protects your cat from feline aids virus.
