Due to a fortuitous run through a hospital parking lot, I secured two doses of Pfizer in March 2021. Back then, we became ‘fully vaccinated’ a full two weeks after completing the course of the COVID vaccine: after your second dose of Pfizer or Moderna or your ‘one-and-done’ Johnson & Johnson. For me, that was mid-April. But is President Biden now ‘more than fully vaccinated’? Or is the definition of ‘fully vaccinated’ about to ‘evolve’ — and are the rest of us Pfizerites set to be downgraded?

It seems worth asking – the goalposts have shifted so many times over the last 18 months as public health officials squabble over what ‘guidelines’ or ‘mandates’ are ‘necessary’ for us all. Even on the booster shot question, the federal government is divided: a CDC advisory committee voted against allowing it for those at risk because of ‘on-the-job’ exposure, while CDC director Rochelle Walensky overruled them and sided with the FDA, who signed off on the booster for the same group of people last Wednesday. ‘I really do hope that it’s going to be a three-dose vaccine,’ Dr Anthony Fauci told Axios last weekend. Wait, so it’s no longer a two-dose vaccine?
