He urged all countries to start a "massive global effort" to vaccinate at least 10% of the population by September < p > today, 75% of vaccines are given in only 10 countries, while in low-income countries, "only 1% of people get at least one dose," says tandesay < p > tandesay said that the world's failure to share vaccines, tests and treatments, including oxygen, is aggravating the imbalance between the opening and closing of pandemics on different tracks“ This is not only a moral stain, but also self defeating in epidemiology and economy. The longer the inequality lasts, the slower the recovery will be. " He warned that more transmission would lead to more potentially dangerous virus mutations, even greater than the devastating delta variant“ The more mutations there are, the more likely one of them is to avoid the vaccine, so let's all go back to the origin. He reiterated that "we are not safe until we are all safe." < p > according to tandesay, the new crown pandemic has killed more than 4 million people, and the death toll continues to rise. This year's death toll is more than twice the total of last year“ The new crown pandemic has taught us a painful but important lesson, including that when health is at risk, everything is at risk.

He said officials were concerned about seeing more breakthrough infections, even mild ones, among fully vaccinated people in the United States < p > as the mutant virus continues to spread in unvaccinated communities, some counties and private enterprises in the United States may choose to enforce mask orders. At present, less than 40% of counties in the United States are vaccinated < p > fudge said he didn't think he would see a comeback in the near future“ What I've seen is that more people are being tested, and more local protective measures are being introduced, and the impetus to encourage people to get vaccinated is stronger.
