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!!

It is pathetic that scientific facts are not debated intelligently before publication in obscure publications that promote conspiracy theor...

RV144: New discoveries from Old Trials.

There have been a series of papers describing the " Antibody Profile " of participants in the partially successful RV144 Trial that I had described earlier. The first paper looking at the antibody type is a paper by Nicole Yates that appeared in Science Trans Med (2014) . Very little is known about the protective role of vaccine-induced IgG3 antibodies for HIV-1. Previously, it was found that a best known anti-HIV-1 antibody, 2F5, is of IgG3 origin. In the paper by Yates et al., they compared antibody profiles of RV144 trial and the VAX003 trial, which was a modification of the RV144 vaccine. Background: RV144 consists of (cladeB/E) ALVAC prime plus 2 protein boosts rgp120 boost VAX003: consists of (cladeB/E) gp120 protein immunogen. Results: *It was found that IgG3 response rates were significantly higher in RV144 compared to VAX003 at peak immunogenicity time point. **V1-V2 IgG3 antibodies correlated with decreased risk of infection in RV144. ...
