WHO pledges nasal spray vaccines

Several pharmaceutical companies around the world are working on a nasal spray vaccine for the coronavirus. This was announced by Sumiya Swaminathan, Chief Scientist of the World Health Organization (WHO), a recording of the broadcast of the briefing is available on Twitter.

Answering the question about the oral vaccine against COVID-19, the representative of the WHO stressed that currently there is no vaccine in this form: all of them are still in the form of injections. However, several nasal spray formulations are under development, Swaminathan said.

Earlier, the WHO said that in the event of a COVID-19 pandemic, there could be more than one primary infection, since the transmission of the pathogen to humans is possible from several animals. So, the coronavirus could spread through multiple sources and even at different periods of time.

As of November 23, there are more than 58.9 million people infected with coronavirus in the world, of which more than 1.39 million have died, and another 37.6 million have recovered. Most of the infected are registered in the USA, India, Brazil, France, and Russia.
