Of the nearly 6,000 babies targeted to be vaccinated for MMR in Samoa, over 480 are still to be immunised.
TV1 Samoa reports the Ministry of Health had aimed to have 5,812 babies vaccinated.
The figures were disclosed on the second day of the Commission of Inquiry into the deaths in July of two babies soon after being administered the Measle, Mumps and Rubella vaccine.
The programme was put on hold after the deaths and several investigations into the Ministry of Health were set in motion including the inquiry ordered by Cabinet.
Police investigations have seen two nurses charged with the manslaughter of the two one year olds.
It is not clear when the MMR immunisation programme will resume.
