I'm sorry I couldn't update it completely ^^;
Guam was exempted from quarantine if the vaccination rate was 75.2% and the PCR test was negative within 72 hours of arrival on July 2nd. In addition, vaccination tours from Taiwan and South Korea have begun, and although little by little, we are beginning to accept travelers from overseas. Japan is still in isolation for two weeks after returning to Japan, so I haven't traveled abroad yet, but Guam is gradually getting ready to accept it, but it's starting to get ready.
The CDC (Centers for Disease Control and Prevention) travel risk index has dropped from level 4 to level 3. The government is pushing to vaccinate 80% of the adult population by July to further reduce risk. It was also announced that the 14-day entry quarantine from May 1st could be eased. If the vaccination rate exceeds 50% as of May 1, and there is a negative proof within 72 hours, the quarantine exemption is expected to be applied.
The age of vaccinated cormorants was also reduced to 16 on March 23.
