TAIPEI, Taiwan — Health care workers received the first shots in Taiwan’s COVID-19 vaccination drive Monday, beginning a campaign that won’t use supplies from China amid uneven distribution of the vaccines globally.

Taiwan has on hand 117,000 doses of the AstraZeneca vaccine, which it is distributing to healthcare workers across 57 hospitals.

Taiwanese premier Su Tseng-chang launched the drive by receiving the first shot at National Taiwan University Hospital in the capital Taipei. “After 30 minutes of rest, there’s no signs of any discomfort,” he said.

The rest period is for monitoring recipients for any adverse reactions.
