The director-general of health, Dr Take Naseri, said Samoa's health system had improved since the deaths of the two toddlers, who were given a deadly anaesthetic mixed with their Measles, Mumps and Rubella vaccine.
Dr Naseri said there was no panic about measles in Samoa but parents are have more confidence in vaccines now and understand the importance of vaccinating their families against the disease.
Parents who refused to vaccinate were also quick to seek treatment from the hospital when their children got sick, he added.
