The largest-ever vaccination campaign in the southern metropolis is scheduled to last for about five to seven days. 

About 1,000 sites across the city have been ready for the vaccination. Local authorities will mobilise the entire medical workers, including those deployed from central establishments, for the drive. 

Checking the vaccine preservation at a cold storage warehouse in the Cat Lai Industrial Park on Thursday, Deputy Minister of Health Nguyen Truong Son said a batch of vaccine delivered to Vietnam will undergo examination, which will take 48 hours, at the Hanoi-based National Institute for Control of Vaccines and Biologicals, and only when the vaccine gets the quality certificate can it be put into use.
