On Jan. 27, 1986, Allan McDonald stood on the cusp of history.

McDonald directed the booster rocket project at NASA contractor Morton Thiokol. He was responsible for the two massive rockets, filled with explosive fuel, which lifted space shuttles skyward. He was at the Kennedy Space Center in Florida for the launch of the Challenger "...to approve or disapprove a launch if something came up," he told me in 2016, 30 years after Challenger exploded.

Vaccination programs work best when as many people as possible get vaccinated, but Latinos in the United States are getting inoculated at lower rates.
