(CNN) The US just added another powerful tool against Covid-19 to its inventory: a third vaccine.

“Starting tonight, 3.9 million doses of J&J will be distributed across all channels, states, tribes, territories and pharmacies and community health centers,” one senior administration official said in a Sunday night briefing call. “Those J&J doses will be delivered as early as this Tuesday morning.”
