The rabies vaccine is mandatory for dogs—it is a clear legal requirement, not a personal choice, much like compulsory third-party liability insurance for driving a car.
Imported vaccines boast high stability, but this unchanging stability is not always an advantage. Strains and excipients that remain the same for decades cannot combat mutated viral strains, especially highly variable upper respiratory viruses.
Domestic vaccines offer greater flexibility, tailored for pets in China. Though their stability may be slightly lower, they deliver better efficacy and cause milder adverse reactions in pets.
Newborn puppies and kittens have maternal antibodies in their bodies, which boost their innate protection but also interfere with vaccine immunity, preventing the pet from producing its own antibodies in response to vaccination.
Maternal antibodies gradually decline between 6–12 weeks after birth, which is why the first vaccine dose is typically given during this period. Antibodies form 21 days after each dose; for ease of memory, the second dose is usually administered one month later.
Maternal antibodies reach their lowest level at around 16 weeks of age—this is the pet’s most vulnerable stage for immunity. If the first (8 weeks) and second (12 weeks) doses are for preventive defense, the third (16 weeks) dose is for full immune coverage and is critically important.
Core vaccines are the fundamental, mandatory vaccines for all pets, regardless of their living environment or breed. They significantly reduce the severity and mortality of life-threatening pet diseases.
Feline Core Vaccine (3-in-1): Protects against feline panleukopenia, calicivirus, and feline herpesvirus.
Canine Core Vaccines (4-in-1 + Rabies): The 4-in-1 vaccine covers canine parvovirus, canine distemper, canine adenovirus type 2, and canine parainfluenza virus; the rabies vaccine is a mandatory separate core vaccine.
Other non-core vaccines (6-in-1, 8-in-1) are optional based on individual needs. More vaccine combinations do not equal better protection: while multi-in-1 vaccines cover more diseases, they may cause mutual interference between antibody responses. Single vaccines deliver stronger efficacy for specific diseases—for example, the rabies vaccine is always a single vaccine.
