In 2021, we published a scoreboard of preferences for four vaccine brands by age and district. Some elderly people did not like AstraZeneca (news of blood clots in Europe) and preferred Moderna. Some preferred BNT (Pfizer‑BioNTech, secured via TSMC); younger people preferred Medigen (homebrew), others distrusted it. The scoreboard turned what could have been vax Vs. anti‑vax energy into “my team Vs. your team” dynamics. People competed vigorously; at the end, everybody got vaccinated. There was no oxygen for an anti‑vax political faction. The principle is pre‑bunk, not de‑bunk.
