On January 14, Maldives Police Service launched an investigation into a Viber (social media messaging application) group campaigning against vaccination, reports The Edition. Police also said that the activity of the group based on the social media platform was initially brought to their attention last year. Having concluded interrogations with those in connection to the case, they were looking further into the matter. Three fresh cases of measles in the island nation that was declared as measles free by the World Health Organization (WHO) in April 2017 have brought the notice of authorities to hard-line extremists refusing to vaccinate their children.
