The "vaccine" you refer to here is racotumomab. It's not a vaccine in the common-parlance sense ("prevents disease"), but a different immunotherapy treatment which is only approved for use in Cuba and Argentina. I'm mildly curious why it doesn't exist in the US. All of the clinical trials in the USA which I can find on that drug are either incomplete[1] or completed-but-without-results[2][3][4]. For all of those trials, "Laboratorio Elea" is the sponsor or a collaborator, so I presume they have the rights to the drug in the USA. That's apparently a company out of Argentina[5]. I don't know why they seem to have given up on getting the drug approved in USA, but wikipedia says "[a study] is underway in Argentina, Brazil, Cuba, Indonesia, Philippines, Singapore, Thailand and Uruguay", though the citation for that seems incredibly suspect[6].
