New Zealand opened its first large vaccination clinic on Tuesday, as it scales up efforts to protect people from Covid-19, TVNZ reports. The clinic in South Auckland will initially serve household members of border workers. The country has controlled community spread of the virus, and considers border workers and their families the most vulnerable to catching the disease. According to Director-General of Health Ashley Bloomfield, 150 people per day will receive jabs at the clinic, though the numbers will be increased. Two more clinics will be opened in Auckland over the next few weeks.
