it seems pretty clear they want to dramatically decrease the birth rate and population. And even if the vaxes just magically stopped today, they will have achieved that goal to a large extent.

The only positive thing I can see with it is that leftists/socialists are predominantly the ones getting killed and neutered by this thing, so perhaps society in 2030 will be considerably more conservative, high-IQ, and patriotic than it is now. There are other scenarios, however.
