COVID-19 in South Korea: Proper Timing for Easing Mask Mandates After COVID-19 Vaccination

Kang, Yun-Jung

OBJECTIVE: As of July 25, 2021, the Korea Disease Control and Prevention Agency reported 1,422 new coronavirus disease 2019 (COVID-19) cases, 188,848 total cases, and 2,073 total deaths (1.10% fatality rates). Since the first severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) case was reported, efforts to find a treatment and vaccine against COVID-19 have been widespread. METHODS: Four vaccines are on the World Health Organization’s (WHO’s) emergency use listing and are approved of their usage; BNT162b2, mRNA-1273, AZD1222, and Ad26.COV2.S. Vaccines against SARS-CoV-2 need at least 14 d to achieve effectiveness. Thus, people should abide by prevention and control measures, including wearing masks, washing hands, and social distancing. RESULTS: However, a lot of new cases were reported after vaccinations, as many people did not follow the prevention control measures before the end of the 14-d period. There is no doubt we need to break free from mask mandates. CONCLUSIONS: But let us not decide the timing in haste. Even if the mask mandates are eased, they should be changed depending on the number of reported cases, vaccinations, as well as prevention and control measures on how circumstances are changing under the influence of mutant coronavirus.
