A potential coronavirus vaccine developed by a tiny biotech appeared to show positive early results in humans.
The results, published Tuesday, are the latest encouraging sign in the global effort to develop a vaccine for the novel coronavirus, which has killed nearly 700,000 people around the world. But the Novavax data, much like results recently published by Moderna and AstraZeneca, are too preliminary to draw any conclusions about how well the vaccine might protect against Covid-19, experts said.There are more than 160 coronavirus vaccine candidates being developed.
The best responses came from volunteers who received two injections of Novavax's vaccine three weeks apart, plus an adjuvant meant to boost its effects. After 35 days, those participants had neutralizing antibody levels that, on average, were roughly four times higher than what was seen in a group of 32 patients who had recovered from the disease.
It's also impossible to directly compare Novavax's product, NVX-CoV2373, against other vaccines in development, said Kathryn Edwards, scientific director of the Vanderbilt Vaccine Research Program in Nashville, Tenn.
