Vanuatu has recorded more than 7,600 Covid-19 cases and 13 deaths since the beginning of the year - and has only 38 percent of its population fully vaccinated.
Secretary-general Dickinson Tevi said getting vaccines to other provinces and outer islands so that more ni-Vanuatu people are inoculated is a challenge for the authorities.
Tevi said the movement restrictions currently in place to stop the spread of community transmissions is also slowing down the process.
