182 The Therapeutic Goods Administration (TGA) has robust policies and procedures for managing conflicts of interest. This applies to both staff and expert committee appointments. All procedures were followed during and after the appointment of Michael Nissen. Dr Nissen is no longer an employee of the Department of Health and Aged Care, but this has no relationship to assertions of conflict of interest made by the Senator. 220 It is not clear what evidence the question is referring to and no reference is provided for the figure quoted. The rate of serious adverse events is very significantly lower than 1 in a 1000 for each of the COVID-19 vaccines. Current evidence both within Australia and world-wide confirms that at a population level, the benefits of COVID-19 vaccination remain greater than the potential side effects from each TGA-approved vaccine. 226 This question has been answered previously – refer to SQ22-000154. 247 There are different types of COVID-19 vaccines approved for use in Australia and each type of vaccine can have different side effects. The AstraZeneca COVID-19 vaccine is called a viral vector vaccine and the Pfizer COVID-19 vaccine is called an mRNA vaccine. These vaccines work in different ways at a cellular level to offer protection against COVID-19, and because of their different cellular mechanisms it is not unexpected that their serious adverse events, although rare, differ in nature.
