The extent to which the ARCoV vaccine is officially approved depends on the results of the Phase III study. Not all mRNA vaccines are successful candidates,” Gao said. If approved, he added, ARCoV could be used as part of the country’s standard Covid-19 vaccination program and as a booster shot.
Dilemma epidemic China
Studies have shown that booster injections are very important, especially for older adults In omicron infection To protect against serious illness and death. However, in mainland China, only 60 percent of people over the age of 60 receive booster injections, leaving 100 million people in that age group unvaccinated. For those over 80, vaccination coverage was much lower – less than 20 percent of them had received a booster dose in March, when the Omicron wave hit.
Zhao said it was difficult to say whether unvaccinated people would receive an approved RNA vaccine because the technology is new. “But from a scientific perspective, they should do so because mRNA vaccines tend to elicit a stronger immune response, especially in more susceptible individuals,” he added.
While the rest of the world is now trying to live with the virus, the most populous country still has very strict policies on Corona. However, the government relaxed entry rules there at the end of June 2022: from now on, incoming passengers will only need to spend seven days in hotel quarantine plus three days at home. Previously 21 days.
But even with a highly effective mRNA vaccine, the Chinese authorities are unlikely to back down from their “zero-Covid” approach. Although it contained most of the pandemic outbreak, it was less successful against the highly contagious variant of omicron.
“The situation will not change until officials change their attitude and allow infection to some extent.”(Yanzhong Huang, Chinese health policy specialist)
