At the beginning of the vaccination campaign against Govit-19Chinese vaccines have saved countless lives. They started projects in Asia, Latin America and the Middle East, and rich countries stockpiled some vaccines with messenger RNA technology. Pfizer And yes Modern.
But many governments have relied on vaccines in the past Sinovac Biotech Or Synoform is now looking for options United States And yes Europe Among the concerns about the effectiveness of Chinese vaccines against delta strain and limited regulation of MRNA supplies in the West.
This option may already appear in customs data China, Gradually rising from December 2020, human vaccine exports fell 21% in August to $ 1.96 billion from $ 2.48 billion in July.
Nicholas Thomas, an associate professor at Hong Kong City University, who edited several books on foreign policy and public health, said that when the Govt vaccines first became available, “people basically took what they could.”
“But then the general public – and not just doctors – got more information about the differences,” he said. “They realized that not all vaccines are equal in terms of safety.”
That change came during a deadly Govt-19 wave in Thailand earlier this year. As cases increased and Southeast Asia emerged as a new hub for the epidemic, the country actively sought to buy vaccines. Only one supplier arrived on time: China’s Sinovak.
Vaccines allowed 70 million people to start the vaccination campaign sooner than expected, but Thailand soon faced the challenge facing authorities in developing countries.
The effectiveness of inactivated vaccines in China ranges from about 50% to 80% in clinical trials. But they are less potent than MRNA vaccines and raise doubts about their effectiveness against delta variability, which is highly contagious.
As a result, the Thai government was the first to use the vaccine. AstraZeneca In people who have already received one dose or two of coronavac prepared by Sinovak.
Although not an MRNA vaccine, Thai studies have shown that the Cambridge-based virus vector vaccine is as potent as the Chinese vaccine, and Pfizer’s dose is still effective.
In a written response to Bloomberg, Sinovak said being admitted to Koronavak Hospital would be effective in preventing deaths from being admitted to the intensive care unit and during infections.
A spokesman said some countries had first used the Sinovac vaccine for the elderly, who would be hospitalized with Covit-19, while younger people would later receive different vaccines, “and this should be taken into account when evaluating Coronavac’s effectiveness.”
Many countries, including Thailand, have “purchased vaccines from multiple suppliers to increase the number of doses available to the population,” the company said.
Even in Pakistan, although the Beijing government’s ally and Chinese vaccines have contributed 84% to its vaccination campaign at all times, few are looking to find Western vaccines: Muhammad Kashif, a 41-year-old delivery boy in Karachi, had to take a rare dose of Moderna’s vaccine agent who came after the vaccine.
Although Sinovak had allowed Thailand to launch its campaign earlier than planned, the 6 million dose coming in October would be the last ship. By 2022, at least 75% of government orders will come from Astra and Pfizer.
Chinese companies have exported about 884 million doses of vaccines from the country, mainly through agreements with countries such as Brazil and Indonesia. This week, Chile began offering coronavirus to children under the age of 6, a strong endorsement of the vaccine underlying the country’s immunization program.
