Remember what they say when vaxx first come out, do your part to end the pandemic.

Last ON data shows unvaxx is 4 times likely contracting virus than vaxx, for now. And we all know the trend but I can leave that part alone.

Now, Delta R0 is about 6.0 to 7.0, and we all know R0 need to below 1 to see infection shrinking. So for the vaxxer, delta R0 is significant lower, about a quarter of original, so about 1.5 to 1.75. Unfortunately means it is still greater than 1, thus pandemic won't be over.

So same logic, DO YOUR PART, TAKE THE BOOSTER! Really double vaxxer should have no excuse to avoid booster.
