J&J Covid Vaccine Found 72% Effective

The FDA has deemed the Johnson & Johnson single-shot COVID-19 vaccine both safe and effective, with an efficacy rate of 72%. A panel will vote on its emergency use authorization, which could enhance the US vaccine rollout. The J&J vaccine can be stored refrigerated for three months, aiding distribution. The US vaccination rate is currently 1.3 million doses per day, hindered by recent weather conditions. J&J plans to provide 4 million doses initially, with 20 million by March's end. Combined with Moderna and Pfizer, this could fully vaccinate 130 million Americans by March.
