Sinopharm announced on 30 December that phase three trials of the vaccine showed that it was 79% effective - lower than that of Pfizer and Moderna.
However, the United Arab Emirates, which approved a Sinopharm vaccine earlier this month, said the vaccine was 86% effective, according to interim results of its phase three trial.
company spokeswoman declined to explain the discrepancy, and said detailed results would be released later, said a Reuters report.
But even ahead of the phase three trial results, the vaccine had already been distributed to nearly a million people in China under an emergency programme.
Professor Dale Fisher, of the National University of Singapore, said then that it was "unconventional" to ramp up a vaccine programme without first going through last stage trials.
"It is normal to wait for an analysis of phase three trials before ramping up a vaccine programme through emergency use authorisation," he told news site CNBC.
