Here’s a few more studies on the efficacy of Vitamin A in measles.

Hussey GD, Klein M. A Randomized, Controlled Trial of Vitamin A in Children with Severe Measles. N Engl J Med. 1990; 3223:160-164. Doi: 10.1.1056/NEJM199007193230304

Frieden TR, Sowell AL, Henning KJ, Huff DL, Gunn RA. Vitamin A Levels and Severity of Measles: New York City. Am J Dis Child. 1992;146(2):182–186. doi:10.1001/archpedi.1992.02160140048019

Rumore MM. Vitamin A as an immunomodulating agent. Clin Pharm. 1993 Jul;12(7):506-14. PMID: 8354037.

Gerster H. Vitamin A–functions, dietary requirements and safety in humans. Int J Vitam Nutr Res. 1997;67(2):71-90. PMID: 9129249.

I also saved them in an easier-to-look-up-for-the-layperson format, with web link instead of doi, and with the date of publication first, so we can see order of publication date at a glance.  Not sure you’d find that useful, but here it is anyway, including your d’Souza review link:
