Yesterday, the National Health Commission released the news that China's 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps have reported a cumulative total of more than 2.9 billion doses of covid-19 vaccine.
At present, the Aomi Kerong variant has become the main epidemic strain in some countries, and the pressure of "foreign prevention import" in China continues to increase, and vaccination is still an effective means to strengthen the prevention and control of the new crown pneumonia epidemic. In the face of a constantly mutating virus, is our covid-19 vaccine still effective? How should vaccines work?
