The deployment of the three vaccines is part of the US$29.7 million System Strengthening for Effective Coverage of New Vaccines in the Pacific Project, which is supporting the introduction of these vaccines in Samoa, Tonga, Tuvalu, and Vanuatu.
Financed by the Asian Development Bank (ADB), the vaccine project was originally established to support the procurement of rotavirus, pneumococcal conjugate, and human papilloma virus vaccines through the United Nations Children's Fund.
