Me and my wife also. And my dad had it over a year ago and just had his blood checked. AND HE STILL HAD THE ANTIBODIES IN HIS SYSTEM. They are wanting to do booster shots because it’s only good for 6 months. My guess would be we are more immune than others and for longer and against the supposed variant strains coming.
And also my mom had it. We are all good to go.
Not it’s only good for six months .... it good for at least 6 months because that’s how far we are out. It’s likely good a lot longer than that
