Researchers presented the results at a meeting of the American Society of Tropical Medicine and Hygiene.
The team hopes for regulatory approval within the next year and a half.
In recent years, there's been loads of research showing cash transfers can have significant benefits for households.
But there's been less research looking at countrywide effects.
To get a broader view, a team of researchers analyzed different health outcomes across 37 low- and middle-income countries with government-sponsored cash aid programs.
Cash transfers helped about 10% more pregnant women get better care, which in turn improved child mortality.
Slightly older kids were more likely to get vaccinated, be fed nutritious food, and about 40% less likely to get diarrheal diseases in places with cash transfers.
Programs that benefited bigger chunks of the population were associated with greater health improvements.
To keep tabs on how influenza is evolving, countries around the globe send samples throughout the year to seven major labs, including the U.S.
Centers for Disease Control and Prevention.
Those labs then analyze the data in collaboration with the WHO.
But sample submission to CDC is down roughly 60 percent as of July, according to Dan Jernigan, a top CDC official who resigned in August.
WHO officials confirmed that other major labs are seeing fewer samples, too, as money for shipping the samples dries up.
If the pattern holds, researchers worry it'll be harder to design a flu shot that keeps up with the virus's evolution.
