ATAGI statement on recommendations on a winter booster dose of COVID-19 vaccine
As part of winter preparedness, ATAGI have provided recommendations for an additional COVID-19 vaccine winter booster dose for select groups who have been identified as being at highest risk of severe COVID-19 disease. These groups include:
- individuals aged ≥ 65 years
- residents of aged care or disability care facilities
- individuals aged ≥ 16 years with severe immunocompromise
- Aboriginal and Torres Strait Islander people aged ≥ 50 years.
The rollout of winter booster doses will commence from April in line with the 2022 influenza vaccination program, with both vaccines able to be co-administered where appropriate. Winter booster doses of COVID-19 vaccines can be administered from ≥ 4 months since the previous booster dose/confirmed SARS-CoV-2 infection (whichever is later).
mRNA vaccines (Comirnaty (Pfizer) or Spikevax (Moderna)) remain the recommended brands for use as booster doses, with Vaxzevria (AstraZeneca) available for those who have a contraindication to mRNA vaccines. Nuvaxovid (Novavax) may be used in circumstances where no other vaccine brand is deemed suitable.
ATAGI suggests that there is currently insufficient evidence at this time to support a recommendation for additional boosters for other individuals. For these groups, protection from a primary course of COVID-19 vaccine followed by 1 booster dose continues to provide good protection against hospitalisation with COVID-19 disease. Further recommendations may be considered in the future as more evidence emerges.

Vocal cord dysfunction/inducible laryngeal obstruction(s) mimicking anaphylaxis during SARS-CoV-2 (COVID-19) vaccination
Researchers at Monash Health have published findings related to vocal cord dysfunction/inducible laryngeal obstruction(s) (VCD/ILO) in relation to incident-associated VCD which may be related to vaccination.
Their findings are related to a case series of ten individuals who were initially labelled as having experienced anaphylaxis following COVID-19 vaccination. These individuals were referred on to a specialist allergy service, where 9 out of the 10 received a second dose of the same COVID-19 vaccine that caused their initial reaction. It was found that 2 out of the 10 individuals met the Brighton Criteria for anaphylaxis, and symptoms recurred in 8 of the 9 individuals who received a second dose, mirroring their initial reactions which had been diagnosed as anaphylaxis.
Clinical features of VCD/ILO overlap with those of the Brighton Criteria for vaccine-related anaphylaxis, with this research demonstrating the need for providers to be able to differentiate between anaphylaxis and VCD/ILO.

The Conversation: Flu, COVID and flurona: what we can and can’t expect this winter
With international borders open and public health measures alleviated, it is highly likely that COVID-19 and influenza will be circulating simultaneously in Australian communities this coming winter.
This article addresses some probable outcomes and provides helpful tips on how people can protect themselves during this flu season.

The New York Times: In Africa, a Mix of Shots Drives an Uncertain Covid Vaccination Push
While many wealthy countries are well on track with their COVID-19 booster rollout using the Pfizer and Moderna vaccines, African countries continue to rely on products and dosing schedules that many researchers believe render lower vaccine efficacy.
With COVID vaccination rates averaging about 14% across the continent, experts reveal that there are several barriers to vaccination to consider and warn that a fifth, potentially more lethal wave is imminent.

CDC: Effectiveness of COVID-19 Pfizer-BioNTech BNT162b2 mRNA Vaccination in Preventing COVID-19–Associated Emergency Department and Urgent Care Encounters and Hospitalizations Among Nonimmunocompromised Children and Adolescents Aged 5–17 Years
A recent study conducted by the CDC and the VISION Network examined 39,217 emergency department (ED), urgent care (UC) encounters and 1,699 hospitalisations among persons aged 5 to 17 years with COVID-19–like illness during April 9, 2021–January 29, 2022. The study employed a case-control test-negative design to estimate the VE of two doses of the Pfizer-BioNTech vaccine in preventing COVID-19 associated hospitalisations in this cohort.

CDC: Effectiveness of 2-Dose BNT162b2 (Pfizer BioNTech) mRNA Vaccine in Preventing SARS-CoV-2 Infection Among Children Aged 5–11 Years and Adolescents Aged 12–15 Years — PROTECT Cohort
The CDC has released the findings of a recent PROTECT study, assessing the efficacy of two doses of Pfizer-BioNTech vaccine in preventing infection from the Omicron variant amongst children 5 to 11 and adolescents 12 to 15 years of age. The study included clinical data from a cohort of 1,364 participants gathered from July 2021 to February 2022.
The report provides evidence that two doses of the Pfizer-BioNTech vaccine is effective in preventing both asymptomatic and symptomatic SARS-CoV-2 infection in this cohort.

New reference page: Japanese encephalitis
An outbreak of Japanese encephalitis virus (JEV), a rare but potentially lethal mosquito-transmitted disease that can cause inflammation of the brain has been detected in Queensland, New South Wales, Victoria and South Australia. While most infections are asymptomatic, it is currently the leading cause of vaccine-preventable encephalitis in Asia.
Our new reference page: Japanese encephalitis addresses key factors including:
- What is JEV?
- What to look for?
- How it is transmitted?
- Epidemiological information
- Prevention
- Vaccine information
