Prime Minister Jacinda Ardern got her first shot of the Pfizer COVID-19 vaccine on Friday, as the country steps up efforts to inoculate its population.

The Pacific island nation shut its borders and set strict lockdown measures to become one of the few countries to have virtually eliminated COVID-19 in the community, but the government is facing criticism for a slow rollout of vaccines.

“I’m smiling under the mask,” Ardern said as she sat down to receive the shot at a vaccination center in Auckland, as the media watched on.

“For me, I never wanted to be amongst the first, for me we needed to get those front line workers but I also need to be a role model and this demonstrates that it’s safe, that it’s effective and that it’s really important that everyone is inoculated when they have their opportunity…,” she said after receiving the vaccine shot.

About 1 million doses of the Pfizer vaccine have so far been administered in New Zealand, a nation of 5 million people. The country’s medical authorities are yet to approve the use of any other vaccine, including AstraZeneca.

The country was on track for everyone eligible to be inoculated by the end of the year, Ardern said last week.

Pressure has been mounting on the government to speed up vaccinations and reopen its borders. Ardern has said having more people vaccinated gives the nation more options at the border.
