No she landed on earth after the nuclear apocalypse around 100 years ago. So she probably treated them with the nightblood that she brought with her from polaris. And the people treated with nightblood pass down the treatment within their blood from there. Remember Unity Day was a story of 100 years ago about how the 12 stations combined together to become one. But the secret was that they bombed the 13th station which was polaris. Which was the same time when Becca escaped on her pod right before it got bombed. So, she would have had around 90 years to pass down the nightblood genetics. So by that calculation they would already have around 4 or 5 generations of people with nightblood by the time The Hundred got down to earth.
