HONG KONG – Hong Kong reported seven more Omicron infections on Friday as the government announced the expansion of the citywide COVID-19 vaccination program to allow more people get the booster shot.

Starting from Jan 1, all adults could receive the COVID-19 booster shot while adolescents aged 12 to 17, who were previously asked to take only one dose of the BioNTech vaccine, could receive a second jab.

The announcement followed recommendations by the Scientific Committee on Vaccine Preventable Diseases on Thursday.

The city on Friday logged five new COVID-19 cases, taking the tally to 12,555. They comprised four imported infections and one imported-related case. All of them involved mutant strains, the center said.

The imported cases involved a 20-year-old woman from Germany and Ireland, a 46-year-old man from Ghana, a 25-year-old woman from Ethiopia, and another 25-year-old woman from Australia. They have all been fully vaccinated, according to the CHP. 

The imported-related case involved a 64-year-old man who lives in On Hei House in Tuen Mun. He is a cleaner at a designated toilet solely for use by preliminary positive imported cases confined at a designated area at the Hong Kong airport while waiting for transfer to hospital. 

As the man may carry the Omicron variant, the government specified on Thursday night the building he lives as a “restricted area” and required all residents there be tested for COVID-19. All results have been negative.

A total of 72 COVID-19 infections have been reported in the past 14 days and all of them were imported.
