Historical Context
The Omicron variant of COVID-19, first identified in South Africa in November 2021, sent shockwaves through global markets and reignited pandemic fears during the holiday season. The hashtag tracked the variant’s rapid spread, its numerous mutations, questions about vaccine effectiveness, and new travel restrictions.
Initial concern about severity was tempered by evidence that while highly transmissible, Omicron caused less severe illness than Delta, especially in vaccinated individuals. The variant would go on to dominate the 2021-2022 winter, but its discovery in late 2021 marked another pandemic pivot point and prompted booster shot campaigns.
