The country of 1.4 billion has largely abandoned its ¡°zero COVID¡± policy. Though overall reported vaccination rates are high, booster levels are lower, especially among older people. Domestic vaccines have proven less effective against serious infection than Western-made messenger RNA versions. Many were given more than a year ago, meaning immunity has waned.¸ðµç »õ·Î¿î °¨¿°Àº Äڷγª¹ÙÀÌ·¯½º°¡ º¯ÀÌÇÒ ¼ö ÀÖ´Â ±âȸ¸¦ Á¦°øÇϸç, ÀÌ ¹ÙÀÌ·¯½º´Â Áß±¹¿¡¼ ºü¸£°Ô È®»êµÇ°í ÀÖ´Ù. 14¾ï¸íÀÇ ±¹°¡°¡ 'Äڷγª Á¦·Î' Á¤Ã¥À» ´ëºÎºÐ Æ÷±âÇß´Ù.
