A man has been left unable to see, walk, speak or breathe unassisted just days after having the flu vaccine.

Shane and his wife Monique Morgan both had the flu shot on November 2nd to help protect their eight-month-old son Briar against the virus.

Less than two days later, Mr. Morgan started to lose feeling in his arms and legs.

After being rushed to Centennial Hills Hospital in Lone Mountain, Nevada, Mr. Morgan spent four days on a ventilator in intensive care while baffled doctors tried to uncover what was wrong.

He was later diagnosed with Guillain-Barré syndrome, which the Center for Disease Control and Prevention (CDC) recognizes as a “very rare” side effect to vaccines.

GBS occurs when a person’s immune system attacks the nerves that control sensation and movement.

This causes progressive paralysis that starts in the feet and moves up through the rest of the body.

Friends of the couple have launched a GoFundMe page to raise $10,000 to pay for their “compounding medical expenses.”

The CDC claims flu vaccines have a “good safety record,” with hundreds of millions of Americans safely having the jab over the past 50 years.

Side effects tend to be mild and include pain at the site of the injection, headache, fever, nausea and muscle aches.
