PHNOM PENH, Jan 24 (Phnom Penh Post/ANN): Nearly 300,000 people have received their fourth doses of Covid-19 vaccines in the first nine days of the vaccination campaign which started on January 14 at public hospitals and health centres in Phnom Penh, according to the Ministry of Health.
Meanwhile, the ministry said more than five million people have received their third doses. These booster shots, it said, are intended to strengthen immunity and prevent serious illness from highly transmissible variants such as Omicron that are able to infect even the vaccinated.
