COVID-19 vaccines that don’t require a needle may be available later this year or next year, a top scientist said.
The experimental vaccines in production use alternative technologies and delivery systems, including oral and nasal administration, and skin patches — methods that are better suited to some groups like pregnant women, Swaminathan said. The promising inoculations are among more than 80 candidate vaccines being studied, some of which are in the early stages and may fail, Bloomberg reports.More Related News
