In the near future a great number of women will be unable to conceive.
This is certain to many people who are able to gaze forward in time.

We have only speculated on how this comes about.
However, a strong hypothesis is that this vaccine makes a lot of women sterile.
Billy Gates' vaccines have done just this in third world tests.
And so, i would add a sterility to one of the side effects to watch out for in this vaccine.
