Airline and other travel stocks fell Tuesday after U.S. authorities called for a pause in the use of Johnson & Johnson's Covid-19 vaccine due to rare reports of blood clotting.

The Food and Drug Administration asked states to halt use of the single-dose vaccine after six people in the U.S. developed a rare blood clotting disorder after receiving the shot. J&J said "no clear causal relationship" has been identified between the blood clots and the vaccine and said it is working with regulators to assess the issue.
