Think I actually received my J&J shot in late June so I was waiting for six months or so to take the booster... I'd much rather take Generex's 'complete' vaccine which could thwart any virus here and to come, would likely be better than anything out there and last for years to come.... it's too bad the FDA is holding us all hostage, while continue to financially help BP and probably itself... and miserable letting so many die while there's a great therapeutic like LERONLIMAB.
