Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Identify the clinical issue. A 3-month-old child has recurrent respiratory illness. This suggests likely immunocompromise or at least significant ongoing illness, relevant for decisions about live vaccines.
Step 2: Classify the vaccines in the options.
Conclusion: Measles vaccine (live attenuated) is contraindicated in a 3-month-old with recurrent respiratory illness suggesting immunocompromise.
Step 2: Classify the vaccines in the options.
- Inactivated polio vaccine (IPV): Killed/inactivated vaccine -- safe in immunocompromised patients, no contraindication.
- Measles (MMR/Measles vaccine): Live attenuated vaccine (LAIV). Contraindicated in severely immunocompromised individuals because the attenuated virus can replicate and cause disease.
- DPT: Contains diphtheria and tetanus toxoids + pertussis antigen. Not a live vaccine. Generally safe; mild illness is not a contraindication though severe illness warrants delay.
- DT: Diphtheria-tetanus toxoid -- not live, generally safe.
Conclusion: Measles vaccine (live attenuated) is contraindicated in a 3-month-old with recurrent respiratory illness suggesting immunocompromise.
