Moderna's vaccine protects 16 monkeys, 30,000 humans await

Moderna Inc.’s vaccine candidate against Covid-19 protected against the virus in a trial that inoculated 16 monkeys, an encouraging step on the path to a defense for humans against the pandemic.

Two injections of the vaccine protected against heavy exposure to the virus at two different levels of dosage. The primates didn’t show any sign of creating enhanced disease, a problem that has occasionally been associated with vaccines.
