Large HIV Vaccine Clinical Trial to be Conducted in South Africa
A large clinical trial of a new HIV vaccine will begin in South Africa later this year.
Last year, a small trial with 52 healthy volunteers was conducted in the country to test the safety and effectiveness of the ALVAC-HIV/gp120 vaccine, CNN reported.
The new three-year trial will begin in November and include 5,400 people at four sites across South Africa. An earlier version of the vaccine was tested in Thailand in 2009 and provided 60 percent protection against HIV after one year, but that fell to 31 percent by the end of the trial.
It was the first time a vaccine had shown to be effective against HIV.
The vaccine has been improved for use in higher-risk populations of sub-Saharan Africa, where a different subtype of HIV exists. Also, a fifth dose of the vaccine will be given in hope of providing longer-lasting protection, CNN reported.
Pro Wrestlers Sue WWE Over Brain Injuries
Dozens of pro wrestlers have filed a class-action lawsuit against the WWE over brain damage suffered in the ring.
The suit filed Monday alleges the wrestlers incurred "long term neurological injuries" while working for the WWE and that the company "routinely failed to care" for them " in any medically competent or meaningful manner" the Washington Post reported.
The WWE also "fraudulently misrepresented and concealed" the nature and extent of those brain injuries, according to the lawsuit filed in U.S. District Court in Connecticut, where the WWE is based.
The lawsuit states: "Instead of upholding its duty to its employees, WWE placed corporate gain over its wrestlers' health, safety, and financial security, choosing to leave the Plaintiffs severely injured and with no recourse to treat their damaged minds and bodies," the Post reported.
"This is another ridiculous attempt by the same attorney who has previously filed class-action lawsuits against WWE, both of which have been dismissed. A federal judge has already found that this lawyer made patently false allegations about WWE, and this is more of the same," the WWE said in a statement.
