Influenza virus hemagglutinin-binding peptides having amino acid sequences represented by, for example, SEQ ID NOS: 1 to 11. These peptides can bind specifically to hemagglutinin participating in the first step of the infection with influenza virus and thus inhibit the binding of the virus to the receptor of the host. Thus, these peptides are useful as preventives for the infection with influenza virus and remedies for influenza.

Why it's free to use
- Filed March 27, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 27, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
