Editor's Notes
- Corneal scarring Associated with vitamin A defiency Historically the most common cause of blindness in children in Africa, India Encephalitis: Older child more typically - High mortality rate Survivors high rate of disability as here Pneumonia & diarrhea: Pneumonia usually bacterial. Most common cause of post-measles death Note also the skin peeling, a characteristic sign of a healing measles rash
- 1. Vaccine does not contain a preservative Needs diluent from manufacturer – not saline, not sterile water, not tap water, etc.
- This is the result of strengthening routine EPI in Bangladesh. As per the data of 2010 CES 52 of 64 district which is more than 80% had already reached > than 80% measles coverage. And the presented figures are valid coverage of children who vaccinated with the first dose before they reach one year of age.
- Imm data: Biases = Recall bias (mostly from verbal recall in absence of imm cards) + Observer Bias as local ANM is often the data collector RJ = Failure to vaccinate; TN = Failure of 1 dose of vaccine.
