On Jul. 18, 2022, Moderna announced that the Therapeutic Goods Administration (TGA) in Australia had granted provisional registration for the use of Moderna’s mRNA COVID-19 vaccine, Spikevax, in a two-dose series of 25 ﾵg per dose for active immunization to prevent COVID-19 caused by SARS-CoV-2 in children aged 6 months to 5 years. Until now, children under six were the only age group not eligible for vaccination against COVID-19 in Australia.

Positive interim results from the Phase 2/3 KidCOVE study, announced on March 23, 2022, showed a robust neutralizing antibody response in the 6-month to 5 years of age group after a two-dose primary series of mRNA-1273, along with a favorable safety profile. The antibody titers in the pre-specified 6 month to 23 month and 2 years to 5 years of age sub-groups met the statistical criteria for similarity to the adults in the COVE study, which satisfied the primary objective of the study. Preliminary efficacy analysis on PCR-confirmed cases collected during the Omicron wave showed similar efficacy estimates against Omicron in the 6-month to 5 years of age group to those in adults after two doses of mRNA-1273.
