Shane Morgan and his wife Monique decided to get flu shots on November 2, believing it would help protect them and young family members ahead of the busy holiday season.

But what they thought was a pro-active measure turned to horror when Shane began losing feeling in his arms and legs.

“About 36-hours after he got the flu shot he started to get sick,” Monique explained to KSNV.

“I never dreamed that any of this could ever happen,” Shane told local media.

Doctors at Centennial Hills Hospital diagnosed Shane with Guillain-Barré Syndrome, a known vaccine adverse reaction characterized by the CDC as an “autoimmune disorder in which a person’s own immune system damages the nerves, causing muscle weakness and sometimes paralysis.”

Monique blames the flu shot for triggering the adverse reaction, which has left Shane in need of a ventilator and a feeding tube.

“It’s the last time anyone in my family will ever get one,” she said, adding Shane would rather have the flu “ten to one” than suffer the debilitating disorder.

Despite Shane’s horrific vaccine injury, a Nevada health official interviewed by KSNV still encouraged people to get the flu shot, saying Guillain-Barré Syndrome is a “rare” condition.

Guillain-Barré Syndrome, or GBS, has also been reported in patients who received the whooping cough (pertussis) vaccine, Gardasil (HPV), and M-M-R II injections, to name a few.

A GoFundMe page has been created seeking donations to help the Morgan family.
