UPDATED COVID BOOSTER UPDATE 2023
ATAGI have recently released updated COVID booster advice for 2023 which has been accepted by the Government and includes availability of new bivalent vaccines. These contain both the original COVID-19 variant and also an updated vaccine against Omicron variant.
• ATAGI recommends a 2023 COVID-19 vaccine booster dose for adults in the following groups, if their last COVID-19 vaccine dose or confirmed infection (whichever is the most recent) was 6 months ago or longer, and regardless of the number of prior doses received:
o All adults aged 65 years and over.
o Adults aged 18-64 years who have medical comorbidities that increase their risk of severe COVID-19, or disability with significant or complex health needs.
• MG would reasonably be considered a medical comorbidity that increases the risk of severe COVID-19, so this applies to essentially all adults with MG.
ATAGI also recommends: bivalent mRNA booster vaccines are preferred over other vaccines.
The bivalent vaccines include: Pfizer Original/Omicron BA.4/5, as well as Pfizer Original/Omicron BA.1 or Moderna Original/Omicron BA.1. Note: Moderna Original/Omicron BA.4/5 is currently under evaluation by the Therapeutic Goods Administration.
Kind regards to all, Stephen Reddel
