Vaccination Coverage

Hepatitis B (HB) vaccination plays a significant role in controlling HBV infection. Different immune mechanisms govern anti-HBs acquisition, titer, and maintenance. Host pre-vaccination immunological status could be targeted for vaccine efficacy.
This study supports SDGs 3 and 6 by suggesting that current methods of cholera control are insufficient at achieving zero transmission of Vibrio cholerae in Haiti, and that large-scale cholera vaccination campaigns are needed alongside improvements in water and sanitation for long-term cholera elimination.
Background: Hepatitis B causes more than 800 000 deaths globally each year. Perinatal infections are a major driver of this burden but can be prevented by vaccination within 24 h of birth. Currently, only 44% of newborn babies in low-income and middle-income countries (LMICs) receive a timely birth dose. We investigated the effects and cost-effectiveness of implementing ambient storage of hepatitis B vaccines under a controlled temperature chain (CTC) protocol and the use of compact prefilled auto-disable (CPAD) devices for community births.
Few public health interventions can match the immense achievements of immunization in terms of mortality and morbidity reduction. However, progress in reaching global coverage goals and achieving universal immunization coverage have stalled; with key stakeholders concerned about the accuracy of reported coverage figures. Incomplete and incorrect data has made it challenging to obtain an accurate overview of immunization coverage, particularly in low- and middle-income countries (LMIC). To date, only one literature review concerning immunization data quality exists.
Background: The WHO Director-General has issued a call for action to eliminate cervical cancer as a public health problem. To help inform global efforts, we modelled potential human papillomavirus (HPV) vaccination and cervical screening scenarios in low-income and lower-middle-income countries (LMICs) to examine the feasibility and timing of elimination at different thresholds, and to estimate the number of cervical cancer cases averted on the path to elimination.
