AstraZeneca's coronavirus vaccine is looking especially promising for the elderly

Another potential coronavirus vaccine is moving along, with especially good news for the elderly.

AstraZeneca announced Monday that its COVID-19 vaccine in development with the University of Oxford has produced a similar immune response in both younger and older adults. The vaccine also results in low adverse responses among older people, the pharmaceutical giant said. That's a standout response considering COVID-19 tends to be more severe in older patients.

Several dozen coronavirus vaccines are in the works around the globe, with AstraZeneca's one of many undergoing clinical testing. It's unclear when AstraZeneca will publish the results of its large ongoing trial that will help determine its vaccine's safety, but it is expected to be one of the first vaccine candidates to seek regulatory approval, Reuters reports. This vaccine is expected to protect people from the coronavirus for about a year.
