New Covid-19 vaccines, including ones that don’t require needles and can be stored at room temperature, may be ready for use later this year or next year, the World Health Organization’s top scientist said.
Six-to-eight new immunizations may complete clinical studies and undergo regulatory review by the end of the year, Soumya Swaminathan, the Geneva-based agency’s chief scientist, said in an interview Saturday…
The current crop of experimental vaccines use alternative technologies and delivery systems, and include more single-shot inoculations, and vaccines that are administered orally, via a nasal spray, and through the skin using a type of patch. These could bring immunizations that are better suited to specific groups, such as pregnant women, according to Swaminathan.
