Hanoi, April 18 : Vietnam has called for an intensified effort in Covid-19 vaccinations by provincial and municipal health sectors, local media reported on Tuesday. The country's National Institute of Hygiene and Epidemiology (NIHE) has allocated 832,900 doses of the AstraZeneca vaccine to all 63 provinces and cities nationwide, Xinhua news agency reported citing local media.
