This question resolves Yes if GiveWell recommends a grant to support cash transfers.
This question will resolve No otherwise.
This question resolves according to GiveWell's spreadsheet here https://docs.google.com/spreadsheets/d/1TG7WRU85p1SEjir-5qvIEg4kVG9a4Lnzdgwcub8aKSs/edit#gid=0 or equivalent or a public statement.
Nathan reserves the right to edit this question within the spirit of the question to make the information more useful to GiveWell in the first 3 months, though will pay anyone who feels they lost out. After that, he will only clarify resolution cases.
That spreadsheet shows that they're actively supporting at least one (conditional) cash transfer program already.
@NathanpmYoung New Incentives (newincentives.org) runs a conditional cash transfer (CCT) program ... seeks to increase uptake of routine immunizations through cash transfers ... makes cash transfers conditional on infants receiving vaccines. [They also do other stuff, but CCT seems a big part of what they do.]
I would guess row 3 in the sheet? "Conditional cash transfers to increase infant vaccination as run by New Incentives"
