There are tons of references to this kind of thing all the way through the original series: smallpox vaccines used to gather DNA samples for identifying human remains after a nuclear war, vaccines developed to counter an alien virus and leaving a standing army immune to biological weapons following an alien invasion, mind-reading data chips implanted in people’s necks (the removal of which causes cancer), allusions to experimentation by the 731 unit and the post war capture of axis scientists, frequent references to PCR tests, homeland terrorism, cabalistic shadow government, experimentation on the human population without their knowledge or consent, AI taking over buildings... the list is endless. All sounded a bit fantastical in the 90s, but worryingly prescient now technology has caught up.
If you were to write a novel about the last two years, it would be rejected on the grounds that it is too dramatic/not believable.
