About 95 percent of Kiwis are getting their second Pfizer vaccine jab within five weeks of their first dose, NZ Herald reveals. That means of the 42,771 people who have had two doses as of Tuesday last week, about 2000 of them had their second jab more than two weeks after the recommended time to receive it. The main disadvantage for them, according to Auckland University vaccinologist Dr Helen Petousis-Harris, is that they may have been more vulnerable to Covid-19 for longer than they otherwise would have been.
