Why flu vaccines are targeted
Demand spikes every autumn and winter, supply is limited, and vaccines are bought by individuals and workplaces outside hospital settings. That combination creates an opening for falsified products, as 2026's alerts show.
Features of a genuine flu vaccine
- Prefilled syringe or vial in a sealed carton
- Season (e.g. 2026/2027) and strain information on the leaflet
