unvaccinated individuals accounted for 89.8% of cases in patients over the age of 18 [4] . First of all, the vaccine uptake rate should be raised to 80% or higher through voluntary participation rather than legal regulations and coercion. Furthermore, mask use (which has increased by 95% compared to pre-pandemic levels) in public places, subways, and buses; hand-washing; ventilation; refraining from holding or attending events; and social distancing [5] are behavioral changes that should be maintained through voluntary responsibility until the end of the pandemic.

A second question is whether relaxation of these mitigation policies will lead to an increase in the number of confirmed cases. On September 25, 2021, the number of new confirmed cases exceeded 3,000 in a single day, but the daily case load is decreasing again due to the strengthening of social distancing measures. However, the proportion of patients managed within the quarantine network is gradually falling. It is now down to 29.9%, whereas just 3 or 4 weeks ago, that percentage was around 35%. This means that ability of the quarantine network to conduct follow-up of confirmed cases has reached its limit [4] . Therefore, as the number of contact tracing-testing-isolation-quarantine (TTIQ) cases and the workload of health workers are increasing without recruiting new personnel, it is necessary to use an application APP that can reverse-check whether a person has overlapped with a confirmed patient so that people exposed to risk can receive prompt testing. The number of confirmed cases should decrease, thereby reducing the burden on the medical care system.

As a third question, if the vaccine uptake rate rises, will we be able to return to our daily lives? It is not an easy question to answer, due to the possibility of emerging new variants and waning vaccine efficacy; however, for the time being, freedom day such as in the UK can not be suggested. Singapore lifted many social distancing measures at the end of June 2021. However, as the number of patients has increased recently, people are again severely restricting their activities, as follows: gatherings of up to 5 people have recently been reduced to 2, all workplaces are telecommuting and schools have switched to distance learning, and booster vaccinations have been started. However, if social distancing is strengthened again, as was the case before June, small business owners will also suffer considerably. Therefore, Singapore created a disaster relief fund worth $650 million (about 569.8 billion Korean won) to support small business owners [6] . In contrast, in the United Kingdom (UK), the number of patients is increasing to a level similar to that observed during the second wave of COVID-19, but the hospitalization rate and death rate are 1 to 2 per 100,000 people by age group. The UK has implemented the following measures: building defenses through pharmaceutical interventions, identifying and isolating positive cases to limit transmission, supporting the National Health Service and social care, advising people on how to protect themselves and others, and pursuing an international approach [7] .

In summary, how can we prepare for the fourth wave in the Republic of Korea? Even if the number of patients increases, high vaccine coverage will enable our medical care system to cope well with a surge in cases, making it unlikely that deaths will occur without medical intervention if booster vaccinations are given to high-risk groups. Although we had issues last year with the seasonal influenza vaccination, it will be given safely this year. While the United States and the UK, where outbreaks occurred in nursing homes or residential facilities, those facilities were closed and patients and residents were sent home and managed through home care, the Republic of Korea had also several outbreaks in nursing facilities in the early days of the pandemic, but the paralysis of medical institutions was prevented by managing mild cases in residential treatment facilities. In 2021, we will strengthen home care if a large surge occurs, exceeding 3,000 cases per day and continuing for more than several days. In addition, TTIQ plays a major role in interrupting transmission and reducing the number of patients, antiviral drug will support the home care policy if it can be supplied. Furthermore, opening the border requires global cooperation with many countries throughout the world, and vaccine coverage is an important indicator for permitting travel and opening the border. The Korean government will actively contribute to scaling up vaccination production and take steps to ensure the fair distribution and donation of vaccines to control this pandemic.
