A 14-month-old girl from Delhi is brought to the immunisation clinic by her mother. The child has received all vaccines as per the UIP schedule up to 12 months of age. The mother reports that the child had a mild upper respiratory tract infection 2 weeks ago but is now fully recovered. What is the most appropriate action regarding immunisation at this visit?

Explanation

## Immunisation Timing and Minor Illness **Key Point:** Minor illnesses such as upper respiratory tract infection are NOT contraindications to immunisation. The child should receive scheduled vaccines as planned. ### Contraindications to Immunisation | Contraindication | Severity | Action | |---|---|---| | **Minor acute illness** (URTI, diarrhoea, low-grade fever) | Not a contraindication | **Vaccinate as scheduled** | | **Moderate to severe acute illness** | True contraindication | Defer until recovery | | **Severe allergic reaction to vaccine component** | Absolute contraindication | Avoid that vaccine | | **Immunocompromised state** | Varies by vaccine type | Assess case-by-case | **High-Yield:** WHO and Indian guidelines state that minor illnesses (URTI, mild diarrhoea, fever <38.5°C) are **NOT reasons to postpone vaccination**. Delaying vaccination due to minor illness increases the risk of vaccine-preventable disease. ### Vaccines Due at 14 Months (16–24 Month Window) According to the UIP schedule, at 14 months the child is due for: 1. **DPT booster 1** (first booster of DPT) 2. **OPV booster** (first booster of OPV) 3. **Measles/MR booster** (if first dose was given at 9–12 months) **Clinical Pearl:** A history of mild URTI 2 weeks ago is completely resolved and poses no contraindication. The child is well at the time of the visit and should receive all scheduled vaccines. **Mnemonic:** **"Minor Illness = Vaccinate"** — Remember that minor acute illnesses are not contraindications; they are actually a good opportunity to vaccinate because the child is already being seen.
