World Health Organization chief scientist Swaminatan said that later this year or next year, there will be new coronavirus vaccines, including vaccines that do not require injections and can be stored at room temperature.
Bloomberg reported that Swaminatan said in an interview last Saturday (13th) that there will be six to eight new vaccines before the end of this year or complete clinical research and regulatory approval.
According to reports, in the year since the WHO declared the COVID-19 pandemic, there are 10 vaccines known to be immune to COVID-19. However, the continued spread of the virus may cause dangerous mutations, and it is also difficult for pharmaceutical manufacturers to complete orders, so the world needs more vaccines. According to Bloomberg data, currently only 122 countries in 233 countries and regions around the world have started vaccination.
Swaminatan said: “We are very excited about the existing vaccines”, but “we can do better”, “I think after 2022, we will see better vaccines.”
Many current trial vaccines use alternative technologies and medications, including one-dose vaccines, oral, nasal sprays, or skin-permeable vaccines. Swaminathan pointed out that different types of vaccines will be more suitable for specific groups of people, such as pregnant women.
