Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One dose (0.5 ml ) Moderna Omicron-XBB containing COVID-19 booster vaccine (Spikevax) and one dose (0.5ml) Seqirus/CSL quadrivalent unadjuvanted Influenza vaccine (Afluria), both administered intramuscularly. A total of 60 participants will be recruited. Participants will be randomised to receive both the COVID-19 and Influenza vaccine in either the same arm (n=30) or in opposite arms (n=30). The same arm group will get both vaccines in the non-dominant arm (left arm for right-handed people). The opposite arm group will get the Moderna Spikevax vaccine in the non-dominant arm (since this vaccine has a higher rate of local reactions) and the Seqirus/CSL Afluria Influenza vaccine in the dominant arm.. Moderna Spikevax will be administered first in both study groups.

Outcomes
Primary outcome [1] 337741 0
The fold difference in the post-vaccination haemagglutination-inhibition (HAI) titre combined to 3 Influenza vaccine strains (H1N1, H3N2 and B/Victoria) in the same arm group vs the opposite arm group.
Timepoint [1] 337741 0
Day 28 post-vaccination
Secondary outcome [1] 433079 0
Number of reported adverse events (AEs) and serious adverse events (SAEs) within 7 days after the receipt of the two vaccine doses. Common side effects from COVID-19 vaccination include a sore arm, redness or swelling of the arm, headache, a fever or tiredness for 1-2 days. Rare side effects include anaphylaxis (severe allergy) and cardiac inflammation (inflammation of the heart). Common side effects of Influenza vaccination include a sore arm, redness or swelling of the arm, tiredness, muscle aches and mild fever. Rare side effects include anaphylaxis (severe allergy) and neurologic (brain and nervous system) conditions such as Guillain-Barre syndrome.

Summary
Brief summary
This study is a randomised open-label trial of administering an Influenza and COVID vaccine on the same day in the same arm or in opposite arms. We will enrol healthy participants who would like to the get the Influenza vaccine and a COVID vaccine booster on the same day. We will randomise participants to receive the two vaccines to the same arm or to opposite arms on the same day and have blood, saliva and nasal fluid tests to follow their immune responses to the vaccines. partcipants have study visits prior to vaccination, day 6 post vaccination and day 28 post vaccination. We are testing the idea that receiving both vaccines the same arm may provide higher levels of immune reponses against Influenza.
