More interesting discoveries from the RV144 trial (Tweeted by ‏@TweetSosa )

A recent paper by a multi-center group looking into the famous "31.2% vaccine efficacy" study (RV144 trial) shows interesting features associated with this protection against HIV-1.

Shuying Li looked at vaccine-induced Fc receptor-mediated antibody function and in this paper, show that a single nucleotide polymorphism in the FcR-encoding genes is strongly associated with protection. Individuals with a  SNP (rs114945036) carrying CC in this SNP had a vaccine efficacy of 15% while those with a CT or TT had a vaccine efficacy of 91% against HIV-1 subtype CRF01_AE with a lysine at position 169 (169K) in the V2 loop.

RV144 is a treasure trove of discoveries.

The world is eagerly waiting for more data and a cure!

Absurd claims by the Nation of Islam regarding Ebola?

A recent article found on finalcall.com is making the rounds on social media.  In a nutshell, the Minister of the Nation of Islam claims that the western world conducted a massive clinical trial of an Ebola vaccine just before the latest  outbreak in West Africa that killed several thousands. Again conspiracy theorists are out to make Ebola as a man-made disaster that is killing Africans. There are some true facts in the story, particularly those about ZMapp being made available to a select few and not available to a large number of patients, especially poor Africans! It would have created quite an outrage if the ZMapp antibody was administered to poor Africans and many died!! The fact that it was tried on some Americans point to the fact that ZMapp did not want to be named and shamed as a company that uses poor Africans as guinea pigs. It is pathetic that scientific facts are not debated intelligently before publication in obscure publications that promote conspiracy theor...
