While it's true that SinoVac is less effective against Omicron, that's not the primary issue. My family got 3 doses, but the last dose was a year ago. The government went for zero COVID as the national strategy and stopped pushing booster shots. Any protection has long worn off if you didn't receive a dose in the past 6 months.China need western vaccines to suvive this wave. mRNA baby!

A large phase 3 trial in Brazil showed that two doses, administered at an interval of 14 days, had an efficacy of 51% against symptomatic SARS-CoV-2 infection, 100% against severe COVID-19, and 100% against hospitalization starting 14 days after receiving the second dose."
