Apia, Samoa – 31 January 2025 – The Samoan Government has acknowledged the generous support of 6,000 doses of Boostrix vaccines from New Zealand. The timely contribution comes as Samoa addresses a Pertussis (Whooping Cough) outbreak, providing crucial support to safeguard public health and protect vulnerable populations.

Boostrix is an adult vaccine that protects against Tetanus, Diphtheria, and Pertussis. This particular vaccine has not previously been available in Samoa, making this contribution an invaluable asset during the current health challenge.

The Boostrix vaccine, authorized by Medsafe New Zealand for adults, is especially recommended for pregnant women. Administering the vaccine during the second or third trimester of pregnancy provides vital protection to infants during the first few months of life, when they are most at risk, until they are able to receive their own vaccinations.

Vaccines will be prioritized for healthcare workers, frontline responders, and pregnant mothers as part of the vaccine distribution plan. It is critical to note that this initiative does not replace the importance of routine immunization services for infants and children. Parents are strongly encouraged to ensure that their children receive vaccinations on time.

As Samoa works to mitigate the effects of the Pertussis outbreak, this support from New Zealand will play a pivotal role in reducing the spread of the disease and protecting lives.
