維生素A Vitamin A × 兒童麻疹死亡率
結論：證據支持
兒童麻疹死亡率使用維生素 A 之證據強度屬最高等級：Cochrane 系統性回顧（Huiming 2005, CD001479）顯示兩劑 200,000 IU 高劑量方案可使兩歲以下住院兒童整體死亡率 RR 0.

兒童麻疹死亡率使用維生素 A 之證據強度屬最高等級：Cochrane 系統性回顧（Huiming 2005, CD001479）顯示兩劑 200,000 IU 高劑量方案可使兩歲以下住院兒童整體死亡率 RR 0.21 (95% CI 0.07-0.66)、肺炎相關死亡率 RR 0.33 (95% CI 0.08-0.92)；WHO 列入 Essential Medicines List 並做出『strong recommendation』；CDC、AAP、Mayo、Cleveland、Harvard 全部一致支持。
Examine 雖未直接列『measles mortality』為獨立 outcome，但 Pneumonia Symptoms 給予 Grade A（n=1713, 5 studies, Moderate Improvement）、Infant Death Risk Grade B（n=1165, 6 studies），與 measles mortality 之治療生理機制高度一致，屬支持性訊號。
所有主要監管/共識來源（WHO/CDC/Mayo/Cleveland/Harvard/AAP）零異議共識，符合 Grade A 標準。

The most common clinical sign of vitamin A deficiency is xerophthalmia, which develops after plasma retinol has been low. The first sign is night blindness, or the inability to see in low light or darkness as a result of low rhodopsin levels in the retina. 來源↗

謹慎
A healthcare professional may give children vitamin A as part of treatment for measles. The dose of vitamin A depends on the child's age. Children with low levels of vitamin A who get measles are more likely to be very sick than are children with recommended levels. Vitamin A supplements do not prevent measles. Getting a measles vaccine is the most effective and safest way to prevent measles. D… 來源↗

The World Health Organization and the American Academy of Pediatrics recommend vitamin A supplementation for all children with acute measles. In developing countries, it has been shown to reduce rates of morbidity and death in measles-infected children. In the United States, children with measles have been found to have low serum levels of vitamin A, with lower levels associated with more sever… 來源↗

In people hospitalized with measles and its complications, especially children 6 months to 2 years, some doctors prescribe high doses of vitamin A. Low levels of this vitamin have been found in children with severe cases of measles. The World Health Organization (WHO) recommends that all children with measles who live in communities where vitamin A deficiency is common should receive vitamin A. 來源↗

Vitamin A may be administered to infants and children in the United States with measles under the supervision of a healthcare provider as part of supportive management. Children with severe measles, such as those who are hospitalized, should be managed with vitamin A. Vitamin A does not prevent measles and is not a substitute for vaccination. 來源↗

台灣社群整體支持「麻疹確診兒童在醫師指示下短期補充高劑量維他命 A」，但更強烈強調疫苗（MMR）優先；對於「平時吃維他命A保健品預防麻疹」普遍持保留或反對態度，並警告脂溶性維他命過量風險。
💬社群實感
資料不足
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為平時補充維他命A可以預防麻疹感染
✓
事實認為CDC偷偷修改維他命A建議＝有陰謀（反疫苗論述）
✓
事實把維他命A當成麻疹「治療藥」而非輔助支持療法
✓
事實以為市售兒童綜合維他命的維他命A劑量足以對抗麻疹
✓
事實誤信「天然療法」可取代MMR疫苗
🩹 社群通報的副作用
- 高劑量過量導致噁心、嘔吐
- 頭痛、頭暈
