New Zealand says it will now use only the Pfizer vaccine to inoculate its population against the coronavirus, departing from earlier plans to use four different vaccines.
Prime Minister Jacinda Ardern announced the strategy Monday, saying the decision was based on the Pfizer vaccine’s effectiveness. She said this would make it easier and fairer for all New Zealanders to have access to the same vaccine.
However, the strategy may also be driven in part by delays in getting vaccines approved. So far, New Zealand’s medical regulators have approved only the Pfizer vaccine and are reviewing two other shots.
