TAIPEI (Taiwan News) — A total of 164 passengers boarded a flight to Guam Tuesday (July 6) for a holiday with a dose of the COVID-19 vaccine as the centerpiece.

The formula, known as “Air V&V” for “vacation and vaccination,” includes the first dose of a vaccine of choice, with the possibility of a second shot if the holidaymakers stay in the U.S. territory long enough.

Interest in the trips surged after the government of Guam ended the quarantine requirement for visitors able to show a negative PCR test from within 72 hours before the flight.

Taiwanese passengers boarding the flight Tuesday morning said they had decided to travel overseas because they had been too far down the vaccine waiting list, as elderly people are still given higher priority in Taiwan, CNA reported.

The day after arriving in Guam, the visitors can receive a jab from one of three brands: Pfizer-BioNTech, Moderna, or Johnson & Johnson.

The first of the 164 passengers who left Taiwan Taoyuan International Airport Tuesday will return on July 10 before spending 14 days in quarantine, though some have opted to stay in Guam for more than 20 days so they can receive the second dose there.

The package tour does not include the fee for the vaccine, which ranges from US$100 (NT$2,800) for the Johnson & Johnson shot to US$200 for the Moderna or Pfizer-BioNTech jab, in addition to US$200 for PCR testing.
