Answer 2

Answer:

Option - D - Nearly 90% of people will be immune to hepatitis B in both regions is the correct answer.

Explanation:

• In the Republic of Kiribati, hepatitis B is very endemic, and coverage of the major technique proved to prevent mother-to-child transmission of the hepatitis B virus, timely birth dose immunisation, was just 66 per cent in 2014.
• Children born at home are particularly vulnerable, as they have restricted access to timely birth dose vaccination (within 24 hours of delivery).
• From November 2014 to May 2015, a project to build relationships between village health volunteers and health workers, as well as educate pregnant women about hepatitis B vaccination, was conducted in 16 communities in Kiribati with poor birth dose coverage.
• Following the project's completion, coverage of timely birth dosage administration rose significantly in both South Tarawa's densely populated capital district and the Outer Islands (from 57 per cent to 83 per cent).
• In South Tarawa, coverage of timely birth dosage administration increased dramatically from 70% to 84 per cent (p=0.001), and in the Outer Islands, coverage increased significantly from 49% to 75% (p0.001).
• Being delivered in a hospital, being born within the research period, and caregivers developing an antenatal birth dosage plan were all linked to a timely birth dose.

Hence, it is proved that nearly 90% of them will obtain immunity to hepatitis B in both regions.
