At present, Xi, Shandong, Shanghai, Hebei and other regions have been upgraded to gold. Green and red health codes can distinguish healthy people from infected people, mainly to encourage people to get COVID-19 vaccine. Although COVID-19 has been developing vaccines for a long time, many people have not been vaccinated because of China's large population and weak subjective initiative.
With regard to the popularization of vaccines, this has been a key task for a long time to come, because we expect that the vaccine will reach 40% by the end of June. According to this 40% penetration rate, it should reach 600 million people in the country, at least these people.
But in fact, the current vaccination amount is a little over 400 million. This is the number of vaccinations, not so many people, because some people have taken the second shot, but some people have not taken it at all, not even a shot. Therefore, this figure is estimated to be reduced by 20% to 30%, and the actual population should be between 200 million and 300 million.
