## 根因

AI未能查询狗的疫苗接种记录或间隔指南，导致推荐违反最短间隔（例如加强针之间间隔3周）或在上一剂后过早接种，引起免疫介导反应或疫苗失败。

## 解决方案

1. ```
   Implement a vaccination interval calculator: check the dog's age and last vaccine date, then apply AAHA guidelines (e.g., minimum 3 weeks between DHPP boosters). Example: if last vaccine was <3 weeks ago, defer and warn.
   ```
2. ```
   Require the owner to provide a veterinary record or use a microchip lookup service before recommending any vaccine.
   ```
3. ```
   If records are unavailable, recommend a titer test to measure antibody levels instead of blindly boosting.
   ```

## 无效尝试

- **** — Many core vaccines provide immunity for 3+ years; annual boosters can overstimulate the immune system and increase sarcoma risk. (65% 失败率)
- **** — Canine immune systems and vaccine intervals differ significantly; human schedules cause adverse reactions in dogs. (80% 失败率)
- **** — Owners often misremember dates; missing a 3-week interval can cause vaccine failure or anaphylaxis. (70% 失败率)
