Researchers are reporting progress in the race to develop a safe and effective vaccine against the new coronavirus. The disease it causes, COVID-19, has killed at least 610,000 people worldwide. More than 14.7 million people have been infected. Two different experimental vaccines have produced strong immune reactions in people involved in the studies. And neither produced serious unwanted effects. The separate research was published Monday in the British medical journal The Lancet.
