“…The Global Pertussis Initiative (GPI) recommends vaccination during pregnancy as a primary prevention strategy, or vaccinating all individuals who have close contact with infants younger than 6 months [ 105 , 107 ]. In Asia, Singapore, South Korea, and Hong Kong, aP vaccination for pregnant women is included in the NIP [ 83 , 87 , 108 ], and whereas it is recommended in Japan and Taiwan, it is not state funded [ 72 , 79 ].…”

“…In East Asian countries, including Japan and China, the NIPs currently include DTP4, and in South Korea, Hong Kong, and Taiwan the NIPs currently include DTP4, plus a DTP5 booster at age 6 years in Hong Kong, age 7 years in South Korea, and age 5–7 years in Taiwan [ 31 ]. In Japan, there is a voluntary recommendation for booster doses at age > 7.5 years and 11–12 years, yet this is not state funded [ 72 ]. Among ASEAN countries, Cambodia, Laos, Myanmar, and the Philippines provide DTP3, Indonesia, Malaysia, and Vietnam provide DTP4, and Brunei, Singapore, and Thailand provide DTP5 [ 17 ].…”

“…The vaccination schedule in Japan includes DTP at 3, 5, 6, and 18 months, yet the routine national immunization program (NIP) does not currently include boosters for adolescents, pregnant women, and adults [72,73]. DTP4 coverage in Japan is more than 98%; however, between 1975 and 1981, wP was not used in Japan because of adverse neurological effects, and although an aP vaccine was introduced, many Japanese adults born during 1975-1981 did not receive vaccination [24].…”

Cyclic epidemics of pertussis (whooping cough) have been observed globally over the past twenty years despite high infant vaccine coverage. The resurgence of pertussis in high-income countries is partly due to waning vaccine immunity in older children and adults, as well as better surveillance and diagnostics. Moreover, in adolescents and adults, pertussis symptoms are mild and similar to common cough syndromes, meaning that it is under-diagnosed in older populations. A systematic search of MEDLINE, EMBASE, and BIOSIS was undertaken to identify studies published between 1 January 1990 and 17 June 2019, with information on pertussis epidemiology, burden of illness, and mortality in school-aged children, adolescents, and adults in Asia. Studies identified for inclusion were reviewed narratively because a statistical comparison was not possible due to the mix of methodologies used.The results showed that in East Asia, including Japan, South Korea, China, and Taiwan, pertussis is circulating in older children and adults. Diphtheria-tetanus-pertussis (DTP4) coverage is high in East Asia, yet outbreaks observed in Japan and South Korea suggest that vaccine-acquired immunity had waned in adolescents and adults. Several school outbreaks in China show that pertussis is circulating in young children, with continued circulation in adolescents and adults. There was a lack of information from Southeast/South Asian countries, although pan-Asian serosurveys showed that recent pertussis infection was common in adolescents and in adults with persistent cough. To conclude, the circulation of pertussis in Asian countries with high DTP4 coverage supports the expansion of routine vaccination to include booster doses for children at school entry and adolescents. However, surveillance is weak or absent in many countries, meaning that the true burden of pertussis, particularly among older populations, is unknown.
