The Wormholes Open in the Lagrange Points

Everybody comes back to earth during vaccine season. Once a century, there is no disease any more. The worm holes open in the lagrange points and they come some. Some come in ships, tiny ones, living spores that carry minds on them. Others already here in virtual realities inside diamond machines. But they make bodies to visit earth and the people here, because it's facine season, so they can remember where they come from.
