They are updating the guidance every month based on the ongoing results. I think they first announced 3 months or 4 months of immunity, and theyve revised that guidance now up to 6 months, I believe.

At some point, a statistically significant number of people in the trial may start to contract COVID, and that will tell us that immunity wanes in that timeframe. I assume they're then test boosters.

On you statements on natural immunity, the issue isn't with who is saying it.

The issues are:

1)The word "usually."

2)Defining a stronger immune system response as "better". It does not follow that the continuing immunity is necessarily stronger, and the statement I quoted from your article in my last post speaks directly to that point.


The only reason that one would need to include natural immunity in any sort of vaccine "passport" (which I'm against anyway) is for someone who does not want to get vaccinated, isn't it? Otherwise, they simply need to go get the shot and the point is moot.
