Un vaccin contra virusului care produce SIDA a fost dezvoltat de o echipă de cercetători francezi şi chinezi condusă de profesorul Jean-Marie Andrieu, de la Universitatea Paris-Descartes, şi de Louis Wei Lu, director la Institutul de Cercetare şi Dezvoltare din Monpellier.
Testat pe macaci, animalul cel mai apropiat cu omul din punct de vedere genetic, vaccinul a protejat 15 animale din 16 de infecţia cu virusul imunodeficienţei maimuţelor, echivalentul HIV la oameni.
Vaccinul, care se administrează oral, este foarte promiţător, spun oamenii de ştiinţă.
Încă de la descoperirea HIV (1983) de către o echipă de cercetători de la Institutul Pasteur din Paris, oamenii de ştiinţă au făcut eforturi susţinute pentru un vaccin contra acestui virus. Astfel, au fost făcute 187 de studii clinice de vaccinare, iar pentru cercetare s-au cheltuit peste 8 milioane de dolari.
