The invention comprises a method of enhancing the immunogenicity of an envelope virus glycoprotein in a host organism. The method comprises administering to the host a composition comprising the virus envelope glycoprotein and at least one oligopeptide derived from the amino acid sequence of the envelope glycoprotein wherein the oligopeptide contains or corresponds to virus-neutralization epitopes. The method and compositions are useful for vaccinating against viruses, such as HIV SIV, HTLV-I, HTLV-II, or any, retrovirus capable of inducing AIDS in its natural host.

Why it's free to use
- Filed March 16, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 16, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
