Misleading phrase in a GiveWell Youtube ad

In a sponsored segment for GiveWell on a video by the channel Half as Interesting, the narrator Sam Denby says:

[...] Personally, I’d give to the Helen Keller Foundation, which I found through GiveWell, because they help save thousands of lives through distributing Vitamin A supplements to children. Vitamin A supplements can help save the lives of children suffering from vitamin A deficiencies and only cost one dollar to deliver a supplement and save a child.

This seems to reinforce the misconception that saving lives in the developing world is incredibly cheap. GiveWell’s cost effectiveness estimates actually range from ~$1500 to ~$27,000 for Helen Keller’s various regional programs, so this is off by 3 OOMs.

I’m not sure if this quote was under GiveWell’s editorial control, but to the extent it was I’m disappointed. Surely GiveWell should try to prevent this kind of thing from happening in the future, even if the sponsoree is speaking for themself, the misleading statement is brief, the misinformation looks favorable to GiveWell, or other charities’ ads are also misleading.
