Mexican regulatory authorities have granted approval for the use of two Chinese coronavirus vaccines — the Coronavac made by Sinovac and another made by CanSino.
The assistant health secretary says the first bulk shipment of an expected 2 million CanSino doses is to arrive Thursday to be finished and bottled in Mexico.
Mexico has so far received only about 760,000 doses of the Pfizer vaccine, which have almost all been used.
The CanSino vaccine reportedly has an efficacy rate of around 65.7%, while the Sinovac dose has been rated as low as 50.65% at preventing infections.
Mexico also expects to get its first AstraZeneca shipment of 500,000 doses Sunday.
