Johnson & Johnson’s Covid-19 Vaccine Protects Monkeys, Study Finds

An experimental coronavirus vaccine developed by Johnson & Johnson protected monkeys from infection in a new study. It is the second vaccine candidate to show promising results in monkeys this week.

The company recently began a clinical trial in Europe and the United States to test its vaccine in people. It is one of more than 30 human trials for coronavirus vaccines underway across the world. But until these trials are complete — which will probably take several months — the monkey data offers the best clues to whether the vaccines will work.

“This week has been good — now we have two vaccines that work in monkeys,” said Angela Rasmussen, a virologist at Columbia University who was not involved in the studies. “It’s nice to be upbeat for a change.”

But she cautioned that the new results shouldn’t be used to rush large-scale trials in humans. “We just can’t

Prototype Vaccine Protects Monkeys From Coronavirus

A prototype vaccine has protected monkeys from the coronavirus, researchers reported on Wednesday, a finding that offers new hope for effective human vaccines.

Scientists are already testing coronavirus vaccines in people, but the initial trials are designed to determine safety, not how well a vaccine works. The research published Wednesday offers insight into what a vaccine must do to be effective and how to measure that.

“To me, this is convincing that a vaccine is possible,” said Dr. Nelson Michael, the director of the Center for Infectious Diseases Research at Walter Reed Army Institute of Research.

Scientists are engaged in a worldwide scramble to create a vaccine against the new coronavirus. Over a hundred research projects have been launched; early safety trials in humans have been started or completed in nine of them.

Next to come are larger trials to determine whether these candidate vaccines are not just safe, but
