[Asia Economy Reporter Seo So-jeong] The decision on whether to administer a booster shot for those vaccinated with the Janssen COVID-19 vaccine will be made before December.

The COVID-19 Vaccination Response Promotion Team announced on the 7th through a press release that "the general public, including those vaccinated with the Janssen vaccine, will reach six months after completing the primary vaccination starting in December," and "a plan for additional vaccination will be established accordingly."

The team explained, "We will thoroughly review overseas cases and vaccination standards to determine the detailed plan, including the target group for additional vaccination and the type of vaccine."

Unlike Pfizer and Moderna, which require two doses, the Janssen vaccine is considered complete after just one dose. However, as breakthrough infections after vaccination have increased, the need for additional vaccination has been continuously raised.

According to the Central Disease Control Headquarters, the breakthrough infection rate among Janssen vaccine recipients was 0.193% (192.8 per 100,000 people), the highest among vaccines administered domestically. This was followed by AstraZeneca at 0.049% (49.3 per 100,000), Pfizer at 0.040% (40.0 per 100,000), and Moderna at 0.004% (3.5 per 100,000). Among those who received heterologous vaccination?different types of vaccines for the first and second doses?the breakthrough infection rate was 0.038% (38.4 per 100,000).

Meanwhile, Janssen announced on the 5th (local time) that it has applied to the U.S. Food and Drug Administration (FDA) for emergency use authorization of a COVID-19 booster shot for individuals aged 18 and older. According to the Phase 3 clinical trial results submitted by Janssen to the FDA, the booster shot administered 56 days after the first dose showed a 94% effectiveness in preventing symptomatic infection and 100% effectiveness in preventing severe disease.
