Do antibodies equal immunity? Maybe not.

Study Calls Into Question Primary Justification for Vaccines

 

A study, B cell maintenance of subcapsular sinus macrophages protects against a fatal viral infection independent of adaptive immunity, published in Immunity, March 2012, found that mice infected with vesicular stomatitis virus (VSV) can suffer fatal invasion of their central nervous system even in the presence of high concentrations of "neutralizing" antibodies against VSV.

The researchers found that while B-cells were essential for surviving a systemic VSV infection through the modulation of innate immunity, specifically macrophage behavior, the antibodies they produce as part of the adaptive immune response were "neither needed nor sufficient for protection."  These findings, according to the study authors, "…contradict the current view that B cell-derived neutralizing antibodies are absolutely required to survive a primary cytopathic viral infection, such as that caused by VSV."

Thanks for the info.

 

I'd love to hear thoughts on this.
