COVID-19 vaccine development
CoronaVac was an inactivated virus COVID-19 vaccine developed by Sinovac.[9] It had been in Phase III clinical trials in Brazil,[10] Chile,[11] Indonesia,[12] Philippines,[13] and Turkey.[14]
It relies on traditional technology similar to the Sinopharm BIBP vaccine and Covaxin, otherwise known as inactivated-virus COVID-19 vaccines in Phase III trials.[15] CoronaVac does not need to be frozen, and both the vaccine and raw material for formulating the new doses could be transported and refrigerated at 2 –, temperatures at which flu vaccines are kept.[16]
A real-world study of ten millions of Chileans who received CoronaVac found it 66% effective against symptomatic COVID-19, 88% against hospitalization, 90% against ICU admissions, and 86% against deaths.[17] In Brazil, after 75% of the population in Serrana, São Paulo received CoronaVac, preliminary results show deaths fell by 95%, hospitalizations by 86%, and symptomatic cases by 80%.[18][19] In Indonesia, real world data from 128,290 healthcare workers showed 94% protection against symptomatic infection by the vaccine, beating results in clinical trials.[20]
Phase III results from Turkey published in The Lancet showed an efficacy of 84% based on 10,218 participants in the trials.[21]<ref na[22] Phase III results from Brazil previously showed 50.7% efficacy at preventing symptomatic infections and 83.7% effective in preventing mild cases needing treatment. Efficacy against symptomatic infections increased to 62.3% with an interval of 21 days or more between the doses.<ref na[23]

According to an investigative report by Reuters, the United States ran a propaganda campaign to discredit the China's Sinovac COVID-19 inoculation, including using fake social media accounts to spread disinformation that the Sinovac vaccine contained pork-derived ingredients and was therefore haram under Islamic law.<ref na[44]
During the COVID-19 pandemic, China's growing influence by donating vaccines and aid, had prompted US military leaders to initiate a covert propaganda operation. A senior US military officer involved with the campaign had told Reuters that the US failed to effectively share vaccines with partners, leaving them without much options but to undermine China's diplomatic efforts. US military leaders took precedence over diplomats, fearing that China's COVID diplomacy might draw South-East Asian countries closer to Beijing. The US government later justified its covert disinformation campaign by framing it as retaliation for China's disinformation, which had falsely blamed the United States for the spread of COVID-19. Additionally, the campaign reportedly aimed to counter "China’s COVID diplomacy", and so to ultimately undermine closer ties between China and countries like the Philippines as a result of such diplomacy during the pandemic. {{[45] The campaign primarily targeted people in the Philippines
