Getting vaccines to people who need them isn’t always easy. Many vaccines require cold storage, making it difficult to ship them to remote areas that don’t have the necessary infrastructure. MIT researchers have come up with a possible solution to this problem: a mobile vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day. This kind of printer, which can fit on a tabletop, could be deployed anywhere vaccines are needed, the researchers say. “We could someday have on-demand vaccine production,” says Ana Jaklenec,…
