I haven't looked deeply at the first appearance of the virus, but I've always thought that the Samoan mandatory measles vaccination was suspicious. Like it was a test run. It gets even weirder now RFK jr is implicated.

Timeline:
June 2019 - RFK visits Samoa. He is accused of campaigning against vaccines but claims it was to study the effects of a largely unvaccinated against measles population. After the death of 2 babies in 2018 the vaccination rates in Samoa plummeted.
August 2019 - allegdly an infected visitor to Samoa starts a measles outbreak
December 2019 - Samoa makes vaccination against measles mandatory.
