Today was the final day of a nation-wide shut down while vaccination teams visit households to administer shots in an effort to stem a deadly measles epidemic.
Josh Green is leading a team of 70 healthcare professionals from Hawai'i assisting in Samoa.
The death toll from the outbreak now stands at 63 measles with one fatality over the last 24 hours.
Mr Green said he had witnessed the toll of the outbreak first-hand but was hopeful of an end in sight, with the government reporting over 17,000 vaccines had been administered over the first day.
