What happened
With the onset of cold season, the quest for a vaccine against the common cold has resurfaced. Colds are caused by various viruses, predominantly rhinoviruses, with around 280 variants complicating vaccine development. Previous attempts to create a cold vaccine in the 1960s and 70s were unsuccessful, and interest has waned since then. However, the economic impact of colds, estimated at $40 billion annually in the U.S., highlights the need for effective prevention. Some researchers are exploring ways to bolster immune responses in at-risk populations, while others have made strides in animal studies. Despite the challenges, there remains cautious optimism about the potential for a cold vaccine in the future.
