The University of Hong Kong has developed a nasal spray that contains a vaccine for both common flu and COVID-19. They plan to start trials on humans next month, reports Nature microbiology. It is assumed that the spray will help destroy viruses, in particular COVID-19, immediately in the nose - from where they usually enter the human body. If immunization against influenza with nasal sprays is already known, the new drug should, as the research scientists hope, also provide protection against coronavirus. Through trials on Syrian hamsters, Chinese scientists in Hong Kong have found certain drugs used to treat infectious diseases are effective in suppressing coronavirus symptoms.. First, for clinical trials of the spray vaccine, they plan to attract about 100 people. During testing, Chinese scientists will investigate, in particular, the safety of the vaccine, as well as the optimal dose for each person.. Scientists have already filed a US patent for the manufacture of such a vaccine. The Ministry of Health predicted the cost of the COVID vaccine Earlier it was reported that in South Korea, biologists have developed a coronavirus vaccine that can be administered not by injection, but through a nasal spray.
