My question is to the Minister representing the Minister for Health, Senator Colbeck. Senator Gerard Rennick has said of the Pfizer vaccine: 'When are these snake-oil salesmen going to be called out? The Pfizer shot doesn't deserve to be called a vaccine.' When asked during Senate estimates what action this minister would take in response, he assured the committee: 'I'm happy to follow up personally with my colleague.' Has the minister personally spoken with Senator Rennick about these comments? If so, when, and what did he say?
