New immunisation reference page: Febrile seizures (Febrile convulsions)
Febrile seizures are typically triggered by a sudden rise in temperature and more commonly occur in very young children. Febrile seizures can be classified as simple or complex, with 1 in 30 children experiencing a febrile seizure at some point during their childhood.
Although vaccines can cause fevers, febrile seizures following vaccination are not common.
Our new reference page provides an overview of febrile seizures and outlines the recommendations following a vaccine proximate seizure.

ATAGI Advice on mRNA COVID-19 vaccine dose intervals and COVID-19 vaccination post infection
ATAGI have provided updated advice on mRNA COVID-19 vaccine dose intervals and COVID-19 vaccination post infection.
It is now recommended that the dose interval between primary doses of mRNA COVID-19 vaccines should be extended to 8 weeks, with the extended dose interval shown to improve effectiveness and immune response to vaccination, as well as potentially also reduce the risk of myocarditis and pericarditis.
ATAGI have also recommended that COVID-19 vaccination is deferred 3 months following COVID-19 infection to optimise protection.

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.

VIC DH: Japanese encephalitis virus detected in Victoria
Several cases of Japanese encephalitis virus (JEV), a rare but potentially serious infection have been detected in pigs in the state of Victoria, New South Wales and Queensland. At this stage, no cases have been reported in humans, but there may be a risk of transmission in regions near the border of Victoria and New South Wales.
More than 90 per cent of JEV infections are asymptomatic, transmitted to humans through the bite of an infected mosquito. The incubation period is usually between 6 to 16 days and illness usually begins with sudden onset of fever, headache and vomiting.
Public health officials have advised clinicians to consider and test for JEV and other arboviruses in patients with unexplained encephalitis, after other common causes such as Herpes Simplex Virus (HSV), Varicella Zoster Virus (VZV) and enteroviruses have been excluded.
Furthermore, it is recommended individuals limit their exposure to mosquitoes and monitor for symptoms if they have travelled around the impacted areas.

ABC News: Chickenpox defies COVID-19 restrictions, prompting vaccination warning
Throughout the pandemic, the highly transmissible varicella zoster virus, which causes chickenpox has continued to spread with more than 10,000 cases recorded in Queensland last year and similar levels observed in 2020.
While the pandemic has shown social and physical distancing to be very effective in limiting the spread of diseases, this article reveals that we can expect to see a number of infectious diseases increase as measures are relaxed.
Immunising against the varicella zoster virus is the best way to protect against infection. Data shows that the vaccine is 95 to 99 per cent effective at preventing severe chickenpox so there is a need to encourage individuals – especially pregnant women – to ensure they are up to date with their vaccinations.

Moderna's COVID-19 vaccine (SPIKEVAX) provisionally approved for use in individuals 6 years and older
The Therapeutic Goods Administration (TGA) has provisionally approved the Moderna COVID-19 vaccine, SPIKEVAX, for use in individuals aged 6 years and older. This follows provisional approvals granted by the TGA to Moderna for the use of SPIKEVAX in individuals aged 12 years and older on 3 September 2021, and on 7 December 2021 the SPIKEVAX booster dose for use in adults 18 years and older.
The TGA carefully assessed the data following the KidCOVE clinical trial which included up to 4,000 participants aged 6 to 11 years across the US and Canada, demonstrating that the immune response to the vaccine in children was similar to that seen in older age groups.
In addition to this, clinical data showed that the safety profile in children is similar to that seen in adults. The most frequent side effects in this age cohort were short term and non-severe. These included injection site pain, redness and/or swelling, axillary (groin) swelling or tenderness, fatigue, headache, fever and muscle pain.
Further advice on the rollout of SPIKEVAX to this age group will be provided to the Government by the Australian Technical Advisory Group on Immunisation (ATAGI).

The Washington Post: Coronavirus vaccine for young children further delayed as FDA reverses course, says it will wait for data on three doses
The Food and Drug Administration (FDA) have announced it won’t make a decision on whether to authorise a COVID-19 vaccine for children younger than 5 until data on a third dose becomes available.
The vaccine trial that commenced on 20th January, was designed to test the safety and efficacy of a lower dose of vaccine and was reported to include 3,900 children between the ages of 6 months and 4 years.
To understand if two doses would provide sufficient protection in children younger than 5, Pfizer and BioNTech have been testing two 3-microgram doses, a small fraction of the adult dose. Smaller doses are expected to trigger an equivalent immune response in children, indicating strong protection.
With the study advancing at a rapid pace, Pfizer and BioNTech will opt to wait for the three-dose data suggesting it may provide a higher level of protection in this age group.

ATAGI recommendations for use of Pfizer COVID-19 vaccine as a booster dose in adolescents aged 16-17 years
The Australian Technical Advisory Group on Immunisation (ATAGI) has made recommendations for use of Pfizer COVID-19 vaccine as a booster dose in adolescents aged 16-17 years.
Evidence demonstrates that waning of protection against the Omicron variant occurs after a two-dose primary vaccination schedule and a booster dose is required to increase protection against infection and severe disease.
This statement addresses the safety, efficacy and epidemiological considerations.

ATAGI Statement on the use of Novavax COVID-19 vaccine (Nuvaxovid)
Following two phase lll clinical trials conducted in the USA/Mexico and in the UK, the Therapeutic Goods Administration (TGA) has granted provisional approval of the Novavvax COVID-19 vaccine in Australia.
Novavax COVID-19 vaccine, also known as Nuvaxovid (Biocelect Pty Ltd/Novavax Inc) is a spike protein-based vaccine with each 0.5mL dose containing 5 micrograms of the of SARS-CoV-2 spike protein and 50 micrograms of Matrix-M as an adjuvant.
Novavax COVID-19 vaccine demonstrated to be highly effective in preventing symptomatic COVID-19 disease in adults in a primary schedule. ATAGI continues to monitor the safety, efficacy and immunogenicity data of Novavax COVID-19 vaccine including in high-risk priority groups and will provide updated recommendations as required.

CDC: COVID-19 Vaccine Safety in Children Aged 5-11 Years November 3 – December 19 2021
Following the administration of approximately 8 million Pfizer COVID-19 vaccine doses in children between the ages of 5 to 11 years, local and systemic reactions were closely monitored and assessed. The incoming data was reported to VAERS and v-safe, the national passive vaccine safety surveillance system, jointly managed by the CDC and FDA. During the span of 3 November to 19 December, 4,249 reports were submitted, of which 97% were for nonserious adverse events.
For the most recent clinical data regarding the safety and efficacy of the Pfizer COVID-19 vaccine in children aged 5 to 11 years, read the full VAERS report.
