ATAGI backs Novavax shot as ‘last resort’ booster

Both the Novavax and AstraZeneca COVID-19 vaccines should only be used as boosters in special circumstances, says the expert group

ATAGI has endorsed use of Novavax’s COVID-19 vaccine as a booster when no other vaccine is suitable and tweaked its advice on AstraZeneca’s shot in an update for immunisation providers.

The committee previously suggested AstraZeneca’s vaccine, Vaxzevria, was a booster option for people who had it as a primary course but now recommends it as a booster “in those who have a medical contraindication to or who decline a booster dose of mRNA vaccine”.
