Abstract:
Given that international and domestic flights now require only adults
to be vaccinated or have negative PCR test results, adolescents’ vacci nation of COVID-19 for safe travel needs urgent consideration. As adults
benefit from vaccination policies that give them priority, now children
may become a source of infection transmission leading to new COVID-19
wave outbreaks [1].
With the new cases surging, 12–17 years old adolescents are rec ommended for vaccination (https://www.cdc.gov/coronavirus/20
19-ncov/vaccines/recommendations/adolescents.html). However, the
hesitation and decreasing roll-out make further worrisome because ad olescents’ immune system development or the elevation of hormones
may let them become more vulnerable to the infection of SARS-CoV-2
and emerging variants.
