路透社刚报道科兴疫苗对小孩omicron有效率是38%, 考虑到我们这里几乎防不住omicron,这个数字还是很好的。
A real world study in Chile showed that CronaVac, the Chinese COVID-19 vaccine manufactured by Sinovac, can effectively protect children aged between 3 and 5 from infection, hospitalization and intensive care unit admission amid a rampant wave of the Omicron variant.
According to the study, a preprint of which was published on Tuesday on Research Square, the estimated effectiveness of the CoronaVac shot was 38.2 percent against infection, 64.6 percent against hospitalization, and 69 percent prevention of intensive care unit admission.
The effectiveness was modest but protection against severe disease remained high, read the preprint report.
It is the world's first published data on the protective effects of the new coronavirus inactivated vaccine in children aged 3 to 5 and a study on effectiveness of the vaccine for this age group after the Omicron variant ravaged the world, Sinovac said in a statement on Wednesday.
The study is conducted by Chilean researchers from the Ministry of Health of Chile. It lasted from December 6, 2021, to February 26, 2022, and focused on the outbreak of the Omicron variant in Chile. Researchers said they did not estimate the vaccine effectiveness against fatal outcomes because only two deaths were observed in the unvaccinated group on February 26, 2022.
