Vaccination in the summer
In the hot season, the risk of infection increases significantly due to the favorable environment for pathogenic bacteria such as Staphylococcus and Escherichia coli, which are commonly found in the feathers and skin of livestock and poultry. These microorganisms can easily lead to infections during immunization if proper sterilization is not maintained. It is crucial to ensure that all syringes used for injections are thoroughly sterilized before use. A single needle should be used per animal to prevent cross-contamination. Boiling is an effective method for sterilization; by boiling for 15–30 minutes, most bacterial spores can be destroyed.
Heat stress can severely weaken the immune response of animals, making vaccination less effective. If feeding and management practices are not adjusted, this can lead to immune failure. During summer, it’s essential to implement cooling measures such as adjusting feed formulas, installing high-power exhaust fans, improving ventilation, and using water curtains. In urgent situations, spraying cool water on the animals and providing chilled drinking water can help reduce heat stress. Adding sodium bicarbonate, ammonium chloride, and vitamins—especially vitamin C and E—to the feed can enhance the animals’ ability to cope with heat stress, ensuring better vaccine performance.
When choosing the method of vaccination in summer, opt for less stressful techniques like drinking water immunization. However, it's important to note that the time the vaccine remains in the water should not exceed two hours, as prolonged exposure can cause the attenuated vaccine to lose potency, leading to ineffective immunity. The amount of water must be sufficient to allow all animals to drink and receive the vaccine. Adding interleukins or protective agents to the vaccine solution can further enhance its stability and effectiveness. While spray immunization causes minimal stress, it requires precise equipment calibration to ensure even distribution and optimal coverage.
Timing is also critical when planning vaccinations in summer. It is best to schedule immunizations during cooler periods, such as early morning or on cloudy days, to minimize heat exposure. This helps reduce the overall stress on the animals and improves the success rate of the vaccination.
Lastly, pay attention to the intervals between vaccinations. Each immunization places a certain level of stress on the animal’s body, so they should not be administered too frequently. Ideally, there should be at least a five-day gap between doses to allow the immune system to respond and recover. Repeated vaccinations without adequate rest can weaken immunity and increase susceptibility to diseases. Therefore, it's advisable to simplify the immunization schedule and avoid unnecessary multiple shots whenever possible.
