It is the first time the recorded deaths have included older children or teenagers. Only one adult has died during the epidemic - a person aged in their 30s.
Samoa's Ministry of Health said this morning that the total number of measles cases reported in the Pacific nation now stands at 2437.
Yesterday, officials said the numbers of cases reported stood at 2194.
"There were 243 recorded in the last 24 hours," a government statement said.
"There are currently 176 measles cases who are in-patients at all health facilities."
The total number of measles cases admitted to any hospital in Samoa, to date, is 766.
Of that, 558 people have been discharged, the Government said.
Officials today removed an earlier ban on any child aged under 19 travelling between the two main islands of Upolu and Savaii.
