Live attenuated vaccine sheds after 28 years

With the global eradication of polio drawing nigh, some researchers are directing their attention to the small fraction of immunodeficient people who can carry strains of the virus derived from the live attenuated vaccine. These prolonged excreters” can shed the virus in their stool for years without ever becoming sick. One man has been shedding the virus since he was vaccinated nearly 30 years ago, researchers reported yesterday (August 27) in PLOS Pathogens. This is the longest that the virus has ever been found to remain in a person who received the live attenuated vaccine.

So far.
Because for once, they looked!

A group of scientists at the National Institute for Biological Standards and Control in Hertfordshire, U.K., have analyzed 185 stool samples from the man over the last two decades. They estimated that the pathogen has circulated in the male patient for 28 years using a molecular clock based on a viral capsid gene sequence; the researchers tracked mutations that may have enabled the virus to diverge from its once avirulent state, according to Live Science. However, this strain does not seem to pose a threat to vaccinated individuals because antibody levels in the blood of immunized people were sufficient to kill the virus, the researchers showed.

Keyword there.
And which group of immunized people, specifically? One dose, two, full, scheduled, childhood, adult, post-illness? What? I always get suspicious of vague immunologists. They’re sneaky bastards that’ll skip town in the dead of night before sending you a note reading: btw you might have Black Death. Like, thanks guys, could have used this information earlier?

In their paper, the authors noted that there may be other long-term asymptomatic shedders of the virus and that sewage monitoring and antivirals could help prevent disease spread from virus shed by prolonged excreters. “Currently no effective strategy to treat these patients,” they wrote.

I’m bored of this.
I”m bored of findings like this coming out, which were theoretically plausible, yet anybody questioning the Mighty Vaccine is supposed to be anti-science? 

cool nothing shocks me scientist indiana jones calm haha amused

Here we have a disease problem, public health risk, caused by vaccines, undeniably, and where is the media attention? The BBC and Guardian are trying to fob it off.
