Doubts about the effectiveness of Chinese vaccines raise concerns at home and abroad

The Omicron range pressured governments around the world to tighten border controls, speed up vaccination and restore social cohesion last week. But in Dalian, China, officials also put the virus at risk in some areas of the northeast port from “middle” to “low”.

In contrast, Chinese health officials and experts said, it shows how Beijing’s unwavering zero-Covid conclusions proved a “magic bullet”, preventing at least 200m deaths and dying 3m. Western hubris, argued, caused a stir and now the Omicron spread could potentially disrupt.

“Western countries could be targeted by Omicron if the nation were to become more contagious, because of their avoidance of epidemics without science and high reliance on vaccines,” reports Global Times.

Boma media crying, however, challenged the skepticism in the minds of many Chinese people about the effectiveness and robustness of the vaccine manufactured in the country as Beijing launched a stimulating shot and offered to three-year-olds.

Doubts about the complexity of the jabs are not limited to the most populous country in the world, with a rate of 2.5bn given to 1.4bn. It also affects the hundreds of millions of people who have received the vaccine developed by Sinovac and Sinopharm – all of them using the non-genetic vaccine that replaces the genes used with mRNA vaccines such as BioNTech / Pfizer and Moderna.

Ben Cowling, a professor of epidemiology at the University of Hong Kong, said “there is a little more uncertainty about the effectiveness of an unused vaccine compared to other widely used vaccines, such as the mRNA vaccine and the AstraZeneca vaccine”.

China cha the recent eruption of Delta – which spread to more than half of the country and closed the population – showed that Chinese vaccines “against disease and spread could not be expensive because strong public health measures were still needed to stem the tide”, Cowling said.

But the epidemic also said “vaccination benefits in the dangerous Covid seem to be high because recent epidemics have included very few cases”.

Variation of Omicron, which is rapid spread to London, New York and Seoul, offering new vaccines and tests.

According to the first detailed study by epidemiologists in South Africa, Omicron has been linked to a higher rate of recurrent coronavirus infection compared to previous waves.

In many developing countries, the Chinese vaccine was needed to save lives at the beginning of the epidemic after the Covax vaccine operation led by Gavi, a UN-sponsored treaty, struggled to achieve it. Distribution goals. Despite the speed and size of the release, uncertainty about vaccination has been established in China and abroad.

This is one of the first things that has happened to the Chinese government. Since the coronavirus was first discovered in Wuhan about two years ago, readers in Beijing have eliminated any signs of opposition or suspicion.

The lack of openness Due to the strength of the jab and its durability it has worried many Chinese people, especially the parents of young and old. According to interviews with social networking sites seen by the Financial Times, parents in recent months have quietly tried to refuse to accept the shooting of their children.

Latin America and the Caribbean, home to about 8 percent of the world’s population, suffer from about a third of all deaths from Covid. While China has almost doubled the number of vaccines such as the US – most of which were distributed through Covax – countries are completely changing the manufacturers.

Last year, the Brazilian state of São Paulo entered into an alliance with Sinovac, as did President Jair Bolsonaro. was criticized in response to his government’s concerns about the Covid-19 crisis. The Chinese vaccine made several injections at the beginning of a vaccine campaign in Latin America that was popular but was won by the Oxford / AstraZeneca jab.

São Paulo officials earlier reported that the CoronaVac vaccine, developed by Sinovac, showed 78 percent effectiveness against mild or severe complications in local trials. But following criticism for the lack of transparency of the data, scientists announced that the total interest rate was 50.4 percent after 50.4 days – beyond the required level of approval – “very few” cases were included.

Researchers at the Butantan Institute in the state, who complete and complete the CoronaVac vaccine in Brazil, said that with 21 days or more between the two doses, they could reach 62.3 percent. But doubts have been raised about the length of the immune system.

Butantan has donated over 100m of CoronaVac, most of which were made from its site. However, there were no other agreements regarding domestic work or any negotiations with the federal government, the spokesman said.

In Singapore last week, the health ministry said people who had received two doses of Sinovac or Sinopharm vaccine would need a third dose starting next month to be considered “vaccinated”.

Although the Chinese vaccine seems to be falling apart, the pace of Beijing vaccine ambassador it will not be easily changed.

“They [the Chinese] took advantage of the smart window and pushed some of the geostrategic priorities – [the acceptance of] Huawei [network technology], Taiwan recognition, ”said Daniel Runde, at the Center for Strategic and International Studies, a think tank in the United States.

Many health experts have also warned that politics are undermining scientific cooperation and negotiations to end the epidemic, especially between the West and China.

Jerome Kim, an immunologist and director of the UN International Vaccine Institute, who has worked with Chinese and Western vaccine manufacturers, warns that jabs are not the only solution.

“All over the world we have seen the effectiveness of vaccines, but still diseases, infections and deaths from Covid-19 are still there,” he said.

“Have we forgotten that vaccines are very effective as a preventive measure, a method that Covid-19 also includes masks, isolation, avoidance, isolation, testing and additional injections?”
