The World Health Organization (WHO) chief scientist said that a better Corona 19 vaccine than the currently available Corona 19 vaccine will be available at the end of this year or next year.
According to Bloomberg News on the 15th (local time), Sumya Swaminatan’s WHO chief scientist said in an online media briefing that “6 to 8 new vaccine systems will complete clinical research within this year and undergo review by regulatory authorities. “There will be more improved vaccines.”
According to Bloomberg News, there are 10 vaccines known to be effective so far since the outbreak of Corona 19. In addition, six to eight new species will be added, according to Swaminatan Chief Scientist. It is known that more than 80 candidate vaccine substances are being tested by each pharmaceutical company.
“Each pharmaceutical company is developing a vaccine that is administered through a nasal spray, a patch applied to the skin, and not a syringe,” said Swaminatan chief scientist. I will do it,” he explained.
He predicted that some of the vaccines under development could be distributed at room temperature, which would increase the spread rate around the world.

Regarding the recent suspension and reservation of AstraZeneca (AZ) COVID-19 vaccine by countries around the world, Swaminatan chief scientist said, “We have not yet found a link between side effects and vaccines.”
“It’s good to have an existing vaccine, but a better vaccine could come out,” he said. “WHO is pushing ahead with a plan to compare 3-4 candidate vaccines under development with placebo (placebo) at the same time.” This is a measure to quickly verify the effectiveness of the vaccine under development.
According to this method, 80% of participants in the trial receive a different candidate vaccine and 20% receive a placebo. “We are discussing with each vaccine pharmaceutical company whether such a clinical trial can be carried out on a global scale,” said Swaminatan chief scientist. “We expect that clinical trials in this way can begin in the first half of this year.”
