FDA approves Johnson & Johnson's single-dose coronavirus vaccine

• Emergency-use authorization boosts Biden's vaccination plans
• J&J effort becomes third vaccine available to US public

The Food and Drug Administration has authorized Johnson & Johnson's vaccine for emergency use, making it the third vaccine available to the US public and securing another vital step in the US fight to control Covid-19.

The decision was a formality after an independent expert advisory panel late on Friday afternoon recommended drug regulators approve the one-shot vaccine.
