Dealing with Failed Canine and Feline Vaccination: Solu

1. Strategies to Prevent Nutritional Deficiencies in Dogs and Cats.

Maintain scientific feeding practices by selecting a nutritionally complete diet for your pets. For puppies under three months, ensure they receive a variety of vitamins and trace minerals. Opt for puppy or kitten milk replacer in their diet, and if possible, use pet goat's milk to soften the food before feeding. Aim for small, frequent meals, ensuring at least three meals a day, and avoid feeding them highfat, highsalt human food. Additionally, maintain a clean and sanitized living environment for your pets, and avoid taking them out, bathing them, or exposing them to unfamiliar dogs and cats until their vaccines are complete. After three months, as dogs and cats enter a rapid growth phase, increase their food intake and supplement with calcium.

2. Preventing Maternal Antibody Interference.

High levels of maternal antibodies can interfere with vaccines, leading to ineffective immunization. Conversely, low levels of maternal antibodies can also result in failure to produce sufficient antibodies to fight off infections. It's best to administer the first vaccine when the puppy or kitten is six weeks old, as the maternal antibody levels are low enough not to interfere with the vaccine but still offer some protection.

3. Preventing Parasite Infections.

Regularly conduct both internal and external deworming to prevent infections. For puppies and kittens over one month and under three months old, deworm for roundworms every two weeks, with Bayer's internal deworming medication as the first choice. For all ages, deworm for protozoa every three months, using options like Baycox or D800. For those already infected, deworm twice to thrice with a one to twoweek interval between treatments. External deworming depends on the environmental temperature, with monthly treatments recommended when temperatures exceed 15°C. Dogs should use products like PetLift or Frontline, while cats, which typically do not go outside, can use Frontline Plus.

4. Avoid Vaccinations During Subhealth Conditions.

Do not vaccinate dogs and cats that are in a subhealth state. New pets should be observed for a week at home before vaccination. For dogs and cats over three years old, it's advisable to have a health check before vaccination. Avoid vaccinations after a change in environment or after a long journey, ensuring the living conditions remain the same for at least a week postvaccination.

5. Drug Use During Vaccination Period.

Choose medications based on the nature of the disease, symptoms, and severity, avoiding unnecessary or excessive use. Avoid using disinfectants, antibiotics, antiprotozoal drugs, and antiviral drugs a few days before and after vaccination. Use immunostimulants like levamisole and interferon to enhance the immune response. Be cautious with corticosteroids, cytotoxic drugs, and sex hormones to prevent harm to the immune system. If vaccination timing conflicts with deworming, prioritize the vaccination schedule, and delay deworming accordingly, ensuring at least a oneweek interval between the two.

6. Vaccine Efficacy.

Vaccines have specific storage requirements. Refrigerate wet vaccines at around 5°C to maintain effectiveness, and store freezedried vaccines in a frozen environment below 0°C. Contrary to some beliefs, vaccines should not be frozen; failure to meet storage conditions can shorten their shelf life.

7. Vaccine Interval.

The timing of vaccinations can vary depending on the pet's breed, the type of vaccine (domestic or imported), and the start of the immunization. Veterinarians should tailor the vaccination schedule to the pet's specific needs. Pet owners should strictly follow the vaccination schedule provided by the veterinarian to ensure a complete vaccination program. In China, dogs can receive Pfizer vaccines starting at six weeks old, with a series of three injections given at 21day intervals, followed by an annual booster. Cats can receive Pfizer's Trifelvax vaccine, starting at two months old, with a series of three injections at 21day intervals, followed by an annual booster.

Summary

Pet ownership demands a "prevention is better than cure" approach. Vaccinate pets at the appropriate age and when they are in good health, visiting a qualified veterinary clinic or hospital. Follow the vaccination schedule provided by a practicing veterinarian. Enhance pet care by ensuring adequate nutrition, regular deworming, prompt veterinary care for illnesses, and avoiding selfadministration of human medications. Since dogs and cats cannot express discomfort and have a high tolerance for pain, it's recommended that older pets over three years old receive an annual health check to catch and treat issues early.
