The Re-Emergence of H1N1 Influenza Virus in 1977

The most famous case of a released laboratory strain is the re-emergent H1N1 influenza A virus which was first observed in China in May of 1977 and in Russia shortly thereafter.

This outbreak marked the return of a seasonal H1N1 human influenza virus after a nearly 20-year absence following its displacement during the 1957 H2N2 pandemic.

Scientists quickly realized that something was unusual about this re-emergent H1N1 strain; it was genetically similar, though not identical, to an H1N1 isolate from 1950.

Initially it was suggested that this virus could have lain dormant or evolved slowly in non-human hosts for decades, but it is now generally assumed that the virus was kept frozen in a yet unidentified laboratory.

Thought I'd share something referring to another lab release from China. Maybe this was Fauci's first grant.

The journal article from 2010 concerns methods in estimating strain divergence times so probably not worth reading in full.

BOTH SWINE/BIRD FLU ARE ACTIVE NOW. So the crap in the flu shot is not accurate. Which leads me to WHY MY 4 YR OLD GRANDDAUGHTER GOT A FLU SHOT, along with 6 FREAKING VACCINES 2 DAYS AFTER COMING OFF AMOXICILIAN FOR THE ‘SEVERE’ FLU? PED NEEDS HIS LICENCE REVOKED.
