BA2 is VERY contagious. If they don’t show a bump in numbers of infected it’s due to natural or otherwise immunity after two years.

Yep. You're right. But how long will that immunity last? Something to keep an eye on.

Efficay of the mRNA vaccines is now shown to be 20-25 weeks, with efficacy only starting between 2-4 weeks. After that period efficacy drops to between 15-20%. If the second show is administered in a timely manner, it will have the same time frame of efficacy. Then the booster should be administered in a similar fashion, after which efficay will drop off on or before 20 weeks, dropping to only 10%. These are the most reliable assessments available on the numbers and time frame.

So 2 shots and a booster will last perhaps a year and 3 months before efficacy drops to close to an unvaccinated individual.

Anyone trying to vaccine-shame anyone else really has no legs to stand on at this point.

It's either continual boosters forever or they are the same as any unvaccinated individual after the above time frame.

This Doctor has been very pro-vaccine. He is a good source for validating the numbers above.
