The Spin
Narrative A
A norovirus vaccine will mark a crucial breakthrough. Norovirus's ability to spread rapidly in close quarters makes it a public health concern. With no current treatment and prevention reliant on hygiene, a vaccine would be a game-changer — potentially reducing the burden of outbreaks and preventing severe cases.
Narrative B
The increase in norovirus cases is a natural consequence of returning to normal social interactions after a long period of COVID-era cloistering. The human immune system needs exposure to common viruses to maintain strength. While a vaccine is always welcome, overreacting to a situation could lead to unnecessary panic and disruption of daily life.
Metaculus Prediction
There is a 60% chance an orthomyxoviridae pathogen will cause the next pandemic, according to the Metaculus prediction community.
