On reports of declining effectiveness of Chinese vaccines, the director of China’s Centers for Disease Control said that in order to increase the effectiveness of Chinese corona vaccines, the dose or dose of the vaccine may have to be increased.
Dr. Gao Fu has advised more than 60 countries using Chinese vaccines to increase the dose of the vaccine to increase its effectiveness.
He said the dose should be increased or the interval between vaccines should be reduced.
Dr. Gao Fu said that the effectiveness of vaccines made around the world changes over time.
Last month, some people were given a third dose of the Chinese vaccine after the first two doses failed in the UAE.
