Now, why do you think this happened? Pfizer gave Australian employees Covid shots from a separate batch than used for the general population. According to NTD News: "According to two executives at Pfizer Inc., Australia-based staff at the pharmaceutical company were provided with their own separate batch of specially imported COVID-19 vaccines. The executives spoke at a hearing in the Australian Senate, where they were questioned by Queensland Senator Malcolm Roberts. An excerpt from the hearing was subsequently shared by Mr. Roberts on his YouTube channel. The shared segment depicts the Pfizer representatives—Dr. Krishan Thiru, Medical Director for Pfizer Australia and New Zealand, and the company’s Head of Regulatory Sciences, Dr. Brian Hewitt—fielding the senator’s questions."
