Australia to wait for data from US children before clearing vaccine here - Sydney Morning Herald

But with low cases and high rates of adult vaccination coverage, Australia will wait to see how the vaccine plays out in reality before approving the shot, with a larger sample size needed to determine the risk of very rare complications, such as the heart condition myocarditis.

Last week, NSW Health Minister Brad Hazzard and Victorian Premier Daniel Andrews expressed optimism about having children in that age group vaccinated this year.

Professor Cheng said another factor in availability of shots for younger children will be acquiring the supply of the lower-dose vaccine, with children in the US approved for a third of the 30-microgram dose given to people aged 12 and over.

In a statement, the Australian and New Zealand Paediatric Infectious Diseases Group said it supported cautious consideration of whether to extend vaccination programs to children aged 5-11, noting their extremely low rates of severe illness from infection with COVID-19.

There were more than 7000 cases and 244 coronavirus hospital admissions in Australian children aged 5-11 from January to the end of October, the group said. But no child under 12 has died from the virus and only a handful have required intensive care.

Professor Robert Booy, an infectious diseases and vaccine expert who has acted as a consultant to vaccine manufacturers including Pfizer, said he supported the decision to wait for more data, noting the US plan to vaccinate its 28 million children in the age group could mean a sample of two million could be available within weeks.

Professor Booy said it was important to note other countries had taken more conservative approaches to vaccination in younger people and the approval process was designed so that health experts could make the best call without bowing to external pressures.
