Wang Huaqing, chief expert of immunization program of China CDC, said: The reason why COVID-19 vaccine was approved for use in the market actually met the most basic requirements. In this case, the state will determine where to supply what vaccine and make unified deployment. We hope to vaccinate as soon as possible, establish an immune barrier as soon as possible, and try not to consider individual differences, because if there is a big difference, there must be a way.

In terms of vaccine research and development in COVID-19, China has always been in the first phalanx in the world. At present, COVID-19 vaccines from five domestic manufacturers have been approved for conditional marketing or emergency use, and all of them are vaccinated free of charge.

Extended data

COVID-19 vaccine cannot wait forever.

At home, there are still people who have a wait-and-see attitude towards the vaccine and don't know whether to fight it or not. At least 70 countries and regions around the world approved or agreed to buy China vaccine, and many foreign leaders were vaccinated with China vaccine early. However, due to the strong control of the domestic epidemic, some people are still waiting to see and expect better vaccines.

Wang Huaqing said: "If everyone delays vaccination, our immune barrier will never be established, and our desire to take off the mask may not come true. If everyone is vaccinated quickly, this barrier may come one day earlier, and we can return to our normal life as soon as possible. "
