DAVID SEYMOUR (Leader—ACT): Thank you, Mr Chair. I'd just like to ask the question—two questions actually. First of all, what is the Government's current advice on vaccine fade, the reducing effectiveness of the Pfizer vaccine over time? There appears to be mounting evidence around the world, particularly in Israel, who started first, that vaccine fade is a real thing. And in light of the Government's current advice, what is the Government's plan for purchasing booster vaccines at present? The Minister's insinuated on several occasions that the information that boosters might be necessary is coming from Pfizer, who are commercially motivated to sell them. I don't know if that really is his view. He might like to clarify, but he certainly suggested it several times.
