The mutated virus has infected 125 people in Guangdong. What is the difference between vaccinated and vaccinated?

The global “breakthrough” of mutated viruses and whether the immune barrier is reliable depends on the speed and strategy of global new crown vaccination.


On June 1, 2021, in Nanhai District, Foshan City, Guangdong, people line up at night for nucleic acid sampling. Picture/People’s Vision The peaceful life of residents in two first-tier cities in China was broken on May 21, 2021. At Yantian Port, Shenzhen, a person who was on board an international freighter performed routine nucleic acid tests and found that he was an asymptomatic person infected with the new crown virus. Liwan District, Guangzhou, 75-year-old Ms. Guo walked to the fever clinic of Liwan District Central Hospital. The nucleic acid test result was positive, and the result of the CDC’s review on May 21 was positive.

Taking the morning tea of ​​this lady Guo as a starting point, dozens of related infected persons appeared in Foshan, Maoming and other places one after another in the next ten days. Among the personnel working on the freighter entering Yantian Port, three Four cases of infection were found within days. As of June 5, the Guangdong epidemic that they have uncovered has reported a total of 125 local infections of new coronary pneumonia, including 89 confirmed cases. At the moment when global navigation is semi-closed, Guangdong, which is responsible for 90% of China’s inbound population flow, will find imported confirmed cases from abroad almost every day. In fact, since the second half of 2020, Dalian, Ruili, Yingkou, etc., where the epidemic has occurred, are mostly port cities.

Guangdong has reported 1,049 confirmed imported cases from abroad until June 5. There have been six local epidemics related to overseas imports in Guangdong before, and the two local infections in Guangzhou and Shenzhen have not touched people’s hearts so often. Following their trajectory, two chains of infection were formed, and two types of virus variants with increased infectivity tried to “break through.” The epidemic came suddenly and quickly. In just ten days, there have been five generations of transmission cases. Huang Guanglie, director of the Guangzhou Municipal Health Commission, pointed out that the virus in this round of epidemic spreads very fast and has a strong spreading power, which places extremely high demands on prevention and control. More than 3.5 million people worldwide have died of new coronary pneumonia. It is estimated that by the end of 2021, the economic losses caused by the new crown will reach 10 trillion US dollars. As the Director-General of the World Health Organization (WHO) Tan Desai said, “The new coronavirus pandemic is far from over.”

The hope of global mobility is pinned on the new crown vaccine. Tan Desai called for every country to be able to vaccinate at least 10% of the population by September, and the vaccination ratio will reach 30% by the end of the year. Guangzhou and Shenzhen are big cities with more than 10 million people. In early May, the coverage rate of the target population of the new crown vaccine exceeded the target of 40%. Not only Guangdong Province, but the entire China’s immune barrier is being built up in an orderly manner. As of June 5, a total of more than 760 million doses have been vaccinated nationwide. In China, the time taken for every additional 100 million doses of new crown vaccination has been shortened from 25 days to 5 days. This wave of epidemic seems to press the fast forward button for a race between virus and vaccine.

With the emergence of multiple variants of the new coronavirus in China, many professionals in the vaccine field told the Caijing reporter that no vaccine can guarantee 100% of vaccinators will not be infected. Even if the infection is only a matter of probability, it does not mean that the vaccine has failed or the quality is not good. This also shows that under the epidemic, even if vaccinated, it is still very important to maintain good hygiene and follow social distancing guidelines. In this round of the Guangdong epidemic, 4 confirmed cases in Guangzhou had received the first vaccination. Lei Chunliang, director of Guangzhou Eighth Hospital, a designated hospital for the treatment of new coronary pneumonia in Guangzhou, said that as long as it is vaccinated, even if two doses of vaccination are not completed, the basic condition is not serious.

Global data show that as of June 4, global vaccination has exceeded 2 billion doses, and more than 440 million people have been fully vaccinated. However, the situation of vaccination in different countries is different. Countries such as Israel, the United Kingdom, the United States, and Singapore have higher vaccination rates. International air navigation cannot be closed for a long time, and exchanges with some countries can be resumed conditionally. This depends on the speed of global vaccine delivery.

Only when everyone is safe will everyone be safe. As Mary Ramsay, head of immunization at Public Health England, said, social isolation and wearing masks may last for several years. Vaccines are the key to returning us to a normal life.
