A team in China said it had given the green light to start developing an inhaled version of its COVID-19 vaccine, Reuters reported. CanSinoBIO and the Beijing Institute of Biotechnology recently obtained emergency authorization in Hungary for the injectable vaccine, Convidecia.
The recently issued EUA follows approval already given by Pakistan and Mexico.
“We are delighted with the Hungarian authority’s authorization for our vaccine, which is an important step forward in the global fight against the COVID-19 pandemic,” said Dr. Xuefeng YU, chairman and CEO of CanSinoBIO, said following the EUA of Hungary. “As CanSinoBIO continues to receive approvals from different governments across different continents, we are focusing on sharpening the production capacity to deliver our one-shot vaccines quickly and safely to countries in dire need of mass protection against this pandemic.”

Soumya Swaminathan told the news office that several experimental candidates are using alternative delivery systems, including more single-thrust stitches and those administered orally, via a nasal spray and even possibly through a skin stain.

“We need to continue to support the research and development of more vaccine candidates, especially since the need for continuous population promotion is not yet very clear,” Swaminathan told Bloomberg News. “So we have to be prepared for that in the future.”
