At MyDoctor, we provide the Quadrivalent vaccine, which shields you against four distinct strains of the influenza virus—two “A” strains (H1N1 and H3N2) and two “B” strains (Victoria and Yamagata lineages).
By covering both B-strain lineages, these vaccines eliminate the risk of a “lineage mismatch,” ensuring you aren’t left vulnerable to a strain not included in older, trivalent formulations.
Our 2026 Flu Vaccine: Fluarix Tetra and Influvac Tetra
For the vast majority of patients, both vaccines are equally effective at preventing severe illness and hospitalisation. Influvac Tetra, being a subunit vaccine, is often noted for having a very low profile of local side effects (like arm soreness), while Fluarix Tetra has decades of clinical data supporting its efficacy across all age groups.
Our doctors can help you decide which is best based on your medical history, but the most important factor isn’t the brand—it’s the timing.
Timing Your Immunity
It takes approximately two weeks for your body to build full antibody protection after the shot. If you are planning to travel during the Southern Hemisphere winter (June-August) or the Northern Hemisphere peak (December-February), we recommend getting vaccinated at least 14 days before departure.
Who Should Prioritize the 2026 Shot?
- Seniors (65+): To prevent severe complications like pneumonia.
- Young Children: Whose immune systems are still learning to recognize these specific strains.
- Chronic Condition Warriors: Those with diabetes or heart disease, where the flu can trigger systemic inflammation.
