Abstract
Maternal and neonatal tetanus (MNT)* remains a major cause of neonatal mortality with an 80%-100% case-fatality rate among insufficiently vaccinated mothers after unhygienic deliveries, especially in low-income countries (1). In 1989, the World Health Assembly endorsed elimination of neonatal tetanus; the activity was relaunched in 1999 as the MNT elimination (MNTE) initiative, targeting 59 priority countries. MNTE strategies include 1) achieving 80% coverage with 2 doses of tetanus toxoid-containing vaccine (TTCV2+)** among women of reproductive age through routine and supplementary immunization activities (SIAs) in highrisk districts, 2) achieving 70% of deliveries by a skilled birth attendant, and 3) implementing neonatal tetanus case-based surveillance (2). This report summarizes progress toward achieving and sustaining MNTE during 2000-2020 and updates a previous report (3). By December 2020, 52 (88%) of 59 priority countries had conducted TTCV SIAs. Globally, infants protected at birth*** against tetanus increased from 74% (2000) to 86% (2020), and deliveries assisted by a skilled birth attendant increased from 64% (2000)(2001)(2002)(2003)(2004)(2005)(2006) to 83% (2014)(2015)(2016)(2017)(2018)(2019)(2020). Reported neonatal tetanus cases worldwide * Tetanus occurring during pregnancy or within 6 weeks of the end of pregnancy; maternal tetanus infection occurs during abortion, miscarriages, or birth with unhygienic delivery. Neonatal tetanus occurs during the first 28 days of life, either following the cutting of the umbilical cord under nonsterile conditions or applying nonsterile traditional remedies to the umbilical stump in an infant without passively (transplacentally) acquired maternal antibodies. The occurrence of less than one neonatal tetanus case per 1,000 live births per year in every district in every country. Neonatal tetanus elimination is considered a proxy for maternal tetanus elimination; the same strategies for elimination are shared. Initially, the total number of priority countries was 57. The creation of Timor-Leste in 2002 and South Sudan in 2011 increased the number of priority countries to 59. ** Tetanus toxoid (TT2+) or tetanus-diphtheria toxoid (Td2+).
