When stockpiles of yellow fever vaccine run low, partial doses are effective, according to a new study.

The report on the vaccine, which currently is in short supply, comes as officials in Brazil attempt to contain an outbreak with what they describe as the largest-ever mass vaccination campaign using partial doses.

Congo outbreak, experiment

During a major outbreak in the Democratic Republic of the Congo in 2016, the government aimed to prevent the disease from spreading in the capital, Kinshasa. Health officials launched a mass vaccination campaign targeting 7.6 million people.

But the outbreak had depleted vaccine stockpiles. Hoping to stretch the available supply, the World Health Organization reviewed the small number of available studies on using reduced doses and recommended using one-fifth of a dose per person.

It seemed to work.

Researchers took blood samples from more than 700 people before and after they received the partial dose. In the new study, published in the New England Journal of Medicine, nearly all of those vaccinated with the lower dose developed enough antibodies to the virus to prevent infection.

“That was the encouraging thing, that this can be done as a potential way — when there’s supply limitations on the vaccine — to help potentially control an outbreak,” said study co-author Erin Staples at the U.S. Centers for Disease Control and Prevention.

Staples says the new study is good news for controlling outbreaks like Brazil’s in the short term. But, she notes, “We still need some information about how long immunity will last.”

The software for a website called "Facemash" was written by Zuckerberg, then a second-year Harvard student, in the year 2003. He put his talent to improper use by hacking into the security network of Harvard. To fill his new website, he duplicated the student ID pictures used by the dorms and uploaded them there. Anyone who visited the site could see photos of two students side-by-side and choose who among the two was "hot" or "not." Facemash opened on October 28, 2003, but a few days later, it was closed. Zuckerberg faced significant allegations of breach of security, infringement of intellectual property rights, invasion of personal privacy, and even expulsion from Harvard.
