[Asia Economy Reporter Ki Ha-young] The quarantine authorities announced that they are reviewing vaccination plans with the possibility of a COVID-19 resurgence this fall in mind.

Lee Sang-won, head of the Epidemiological Investigation and Analysis Division at the Korea Disease Control and Prevention Agency's Central Disease Control Headquarters, said at a regular briefing on the 5th, "The vaccine's effectiveness has been maintained so far, but there is a possibility of weakening, and due to seasonal effects in the fall, another outbreak could occur. We are reviewing vaccination plans to prepare for the possibility of a resurgence in the fall and winter, in addition to the 4th dose."

Regarding concerns that the amount of vaccine waste will increase due to stagnant vaccination rates recently, he responded, "Vaccination is always necessary," adding, "We are adjusting the timing of vaccine introduction and establishing additional utilization measures considering expiration dates."

This year, 105 million doses of vaccines will be introduced domestically. This quantity was pre-purchased for reasons such as additional vaccinations. However, there are concerns that if vaccinations do not continue, the amount of vaccine waste will increase.

Regarding concerns that vaccine effectiveness may decrease due to the emergence of new variants during the fall resurgence, he said, "Even if it is a variant, the change in vaccine effectiveness can vary greatly. The emergence of a completely novel virus is possible, but a virus that is quite adapted is still possible." He added, "We are continuously analyzing and monitoring variants. We will comprehensively analyze and reflect these factors to establish vaccination plans."

On the opinion of donating surplus vaccines to developing countries, Lee responded, "Since this concerns policies with other countries, it is difficult to comment at this time."

The quarantine authorities are discussing shortening the isolation period for confirmed cases from the current 7 days to 5 days, among other options. They are also considering lowering COVID-19’s infectious disease classification from level 1 to level 2.

Regarding this, Lee explained, "Countries that have shortened isolation periods mostly considered the virus's survival ability while focusing on efforts to prevent social function paralysis. We are reviewing these points. There are pros and cons on both sides." He continued, "It may vary depending on how COVID-19 patients can be accommodated and managed within the general medical system. Once post-Omicron response systems are established, we will provide explanations."
