Anti-vaxxer campaigners are leaving one-star reviews on the Government of Samoa's Facebook page, expressing their opposition to vaccinations in the wake of the measles epidemics on the island.
A total of 65 people have died of measles in Samoa since the outbreak and the number is expected to rise.
Most of the deadly victims were under 5 years old.
The government of Samoa launched a mass vaccination campaign to try to stop the spread of the deadly disease as it continues to claim lives.
