This is AWESOME!!!!
A 103-year-old Red Sox superfan beat the hell out of coronavirus ... and then celebrated like she had just won the World Series -- cracking open and chugging a Bud Light!!
The badass great grandma is Jennie Stajna ... and just a few weeks ago, her family didn't think there was any chance the beer celly would ever go down.
Stajna's grandson-in-law, Adam Gunn, tells TMZ Sports ... the die-hard Boston fan was diagnosed with COVID-19 in early May and became seriously ill.
Gunn says Stajna was the first to test positive in her Wilbraham, Mass.
