SMH: The flu shot: when is it safe to get it after having COVID?
With flu season underway in Australia and an increasing number of cases already confirmed, people are encouraged not to delay their yearly influenza vaccine, which is recommended for anyone 6 months of age and over.
The article features MVEC’s A/Prof Nigel Crawford, who addresses the key considerations such as ideal timing for the influenza vaccination, considerations for people with underlying medical conditions, advice for parents regarding children, and when to get the influenza vaccine post COVID-19 infection.

Moderna: COVID-19 Vaccine Phase 2/3 Study in Children 6 Months to ≤ 6 Years successfully meets its primary endpoint
Moderna has announced interim data from the Phase 2/3 KidCOVE COVID-19 vaccine study ahead of its submission to global regulatory bodies.
Approximately 4,200 children aged 2 to <6 years and 2,500 children aged 6 months to <2 years were recruited across the U.S. and Canada with participants receiving 2 doses of 25 μg, 28 days apart (a lower dose compared with older age groups).
Moderna reports immunogenicity consistent with that seen in adults (18-25 years) receiving doses of 100mcg with a vaccine efficacy of 43.7% in those aged 6 months to <2 years and 37.5% in those aged 2 to <6 years. Omicron was the predominant COVID-19 strain circulating during this trial.
Adverse events following vaccination were reported as mild or moderate and more frequently associated with dose two. No deaths, myocarditis, pericarditis, or cases of multisystem inflammatory syndrome in children (MIS-C) were reported. Independent safety monitoring will continue for 12 months following the second dose.

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.

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 resource: NCIRS Decision aid (5–15 years): Should I get the COVID-19 vaccine for my child?
NCIRS have designed a new decision aid resource to help families make an informed decision about whether COVID-19 vaccination is right for their children.
The tool provides evidence-based information about the disease and the vaccine and takes the user through five simple steps to help weigh up the risks and benefits of vaccination.

Clinical recommendations for COVID-19 vaccines- updated booster advice
The Australian Technical Advisory Group on Immunisation (ATAGI) have provided updated recommendations on the use of booster doses of COVID-19 vaccines:
- Individuals aged 18 years and above are recommended to receive a single booster dose of either mRNA vaccine (Pfizer or Moderna), 3 months after the completion of a primary course of vaccination.
- Individuals aged 16-17 years are recommended to receive a single dose of Comirnaty (Pfizer) as their booster, 3 months following the completion of their primary course. Alternate COVID-19 vaccine brands are not registered for use as a booster dose in this age group.
- Whilst Nuvaxovid (Novavax) is not TGA-registered for use as a booster dose, ATAGI recommends that it may be used as a booster in individuals aged 18 years or older in circumstances where there is a contraindication to mRNA vaccines. There is limited safety and efficacy data to support the use of Nuvaxovid as a booster dose, however there are no theoretical concerns.
- Vaxzevria (AstraZeneca) is no longer recommended for use as a booster dose. Individuals who have already received Vaxzevria (AstraZeneca) as their booster dose do not need a repeat booster dose of an alternate brand.

ATAGI recommendations on the use of Spikevax (Moderna) COVID-19 vaccine in children aged 6 to 11 years
Following the TGA’s provisional approval, ATAGI has put forth a guideline that recommends the use of Moderna’s COVID-19 vaccine (Spikevax) in children aged 6 to 11 years.
Clinical data supports that Spikevax produces a strong immune response and reduces the likelihood of children in this cohort developing COVID-19.
This statement addresses the recommendations, considerations and rationale for the use of Moderna’s COVID-19 vaccine in children aged 6 to 11.

The Conversation: The Moderna vaccine is now available for 6 to 11 year olds. Here’s what parents need to know
The Moderna COVID-19 vaccine is now approved for use in children aged 6 to 11 years. With just under half of Australian primary-school-age children having received their first COVID vaccine dose, the approval of Moderna’s COVID vaccine provides parents with an additional opportunity to protect their children against severe disease.
Following the KidCOVE clinical trial, this article explores the ongoing safety and efficacy as well as the considerations and administrative recommendations for the use of Moderna’s COVID-19 vaccine in the 6 to 11 years cohort.
