The Chinese Sinopharm vaccine for Covid-19 can offer immunity for nine months, a top expert said after assessing the data collected so far from the clinical trials of the inactivated SARS-CoV-2 vaccine.
Last year, Abu Dhabi-based G42 Healthcare and Sinopharm CNBG successfully conducted the world’s first Phase 3 clinical trials in the UAE. The Phase 1 and 2 trials done by Sinopharm in China saw 100 per cent of volunteers generate antibodies after two doses in 28 days.
Dr Walid Zaher, chief research officer and vaccine project leader of G42 Healthcare, said data from the trials and further follow-ups hold the key in determining how long the immunity lasts.
