Combination Vaccine Coverage Worldwide and in Selected Countries

Early data show that as of October 2012, 114 countries globally had included pentavalent vaccines in their immunization programs1. According to the World Health Organization and United Nations Children’s Fund estimates for country-level immunization coverage (WUENIC), the number of countries that have included pediatric pentavalent vaccines had grown to 132 in 2017-20182. By 2020, with the support of Gavi, 73 low-income countries had introduced the pentavalent vaccine2. In recent years, some countries have begun to use the hexavalent vaccine to replace the pentavalent vaccine. According to a study, by 2019, the hexavalent vaccine had been marketed and used in over 100 countries worldwide, with 35 countries introducing it into their immunization programs3.

The Global Alliance for Vaccines and Immunization (Gavi) has been providing combination vaccine for children in the world’s least developed countries since 2001. In 2000, only less than 1% of children in the 67 countries Gavi-eligible countries had been vaccinated with pentavalent vaccines. In 2019, pentavalent vaccines reached a full coverage rate of 82% of school-age children in those countries, with declining slightly to 78% and 77% in 2020 and 2021. By the end of 2021, more than 661 million children from Gavi-eligible countries had received pentavalent vaccines4.

In November 2018, the GAVI Secretariat pre-approved a support program for hexavalent vaccines, with the aim of facilitating efforts to eradicate polio and further enhance global coverage of combination vaccines.

There are different strategies to mitigate the VPDs’ disease burden. The combination vaccines included in the National Immunization Programs (NIP) vary in different countries. We outlined the coverage and types of vaccines targeting diphtheria, tetanus, pertussis, measles, mumps, rubella, hepatitis B, Hemophilus influenzae type b, and varicella in selected case countries. Many low- and middle-income countries obtain the pentavalent vaccine through Gavi, while developed countries predominantly use high-valent combination vaccines for childhood immunization programs. For example, in European countries like the United Kingdom, France, and Germany, the hexavalent vaccine has been prioritized in their childhood immunization schedules.

Types and coverage of selected pediatric vaccines among 0-6 years old children against DPT, MMR, hepatitis B,Haemophilus influenzae type b (Hib) and varicella in selected case countries

Case country 1: United Kingdom

The British immunization schedule includes hexavalent vaccines (DTaP-Hib-HepB-IPV) with first, second, and the third primary dose given at 2, 3 and 4 months of age and a booster dose using DTaP-IPV quadrivalent vaccine at 3 years old. The United Kingdom offers monovalent Hepatitis B vaccine to high-risk children who were born to mothers infected by Hepatitis B virus. The administration schedule has three additional doses of monovalent Hepatitis B vaccine at birth, 4 months, and 12 months. The varicella vaccine is not part of the UK Childhood Immunization Program and is only offered to those who are at high risks and have close contact to people with varicella.

According to 2021-2022 National Health Service (NHS) statistics, the coverage rate of the hexavalent vaccine (DTaP-Hib-HepB-IPV) among the British infants aged 12 months was 92.3%, with the highest in Scotland at 96.3%, and in the Welsh, Northern Ireland and England were 95.2%, 93.5% and 91.8% respectively5. Coverage of the hexavalent vaccine (DTaP-Hib-HepB-IPV) was 93.5% among British infants aged 24 months, 97.1% in Scotland, and 96.3%, 95.3%, and 93.0% in Wales, Northern Ireland, and England respectively.

After September 2017, the pentavalent vaccine (DTaP-IPV-Hib) in the British National Immunization Program (NIP) were replaced by the hexavalent vaccine. Additional protection against hepatitis B infection was provided for all infants born after August 1st , 2017.  According to data disclosed by the NHS from 2021 to 2022, among the under-5-years British infants, the coverage of the first dose pentavalent vaccine is 94.8%, with the highest in Scotland at 97.4%, followed by Northern Ireland at 96.7%, and 96.4% and 94.4% in Wales and England5.

Coverage of the pre-school DTaP-IPV booster shot reached 85.3% among children aged 5 years, with Scotland continuing to have the highest coverage rate at 92.7%, followed by Wales at 91.2%, Northern Ireland at 89.7% and England at 84.2%.

First dose MMR vaccine reached 93.8% among 5 years old children, with coverage of over 95% in Scotland, Wales and Northern Ireland, and the proportion of young children with full course immunization (including two doses) was 86.5%. The coverages in Scotland and Wales are over 90%, with Northern Ireland close to 90% and England only 85.7%.

Case country 2: France

The French immunization program includes hexavalent vaccine (DTaP-Hib-HepB-IPV) with different immunization schedule. The first dose is given at 2 months followed by the second and third dose at 4 and 11 months respectively. DTaP-IPV quadrivalent vaccine is given at 6 years old as booster dose. Similar to the United Kingdom, the hepatitis B monovalent vaccine is only offered to newborns who are at risk of hepatitis B infection through mother-to-child transmission.

Vaccines included in the U.S. Vaccines for Children (VFC) program

In the United States, eligible children can receive free government-funded vaccines through the Vaccines for Children (VFC) program, which includes not only the traditional monovalent and low-cost vaccines, but also nearly all of the quadrivalent, pentavalent, and hexavalent vaccines available in the market. The use of higher-valent combination vaccines can be determined by consulting the pediatrician during the vaccination visit.

According to the National Health and Morbidity Survey of Malaysia (NHMS), the first dose coverage of Pentavalent vaccine in 2016 reached 89.8%, and the full vaccination (three doses) rate was 89.0% 11.

Case country 7: Japan

Japan has been relatively conservative in using the pediatric combination vaccines. A series of adverse events after the MMR vaccination in 1989 makes Japanese policymakers be cautious about vaccine-related risks. It was not until 2012 that Japan began using conjugate vaccines containing polio antigens. The Japanese government favors products with excellent safety records when selecting vaccines.

According to the statistics from the Ministry of Health, Labor and Welfare in Japan in 2020, the coverage rate for the first dose of the measles-rubella (MR) bivalent vaccine was 98.5%, and the full-dose coverage rate was 94.7%. For the DTaP-IPV quadrivalent vaccine, the first dose coverage was 101.3%, and the full vaccination rate was 105.5% (the target population refers to the population that newly meets the immunization criteria each year, while the implementation population refers to the total number of people who receive immunization among those who are eligible each year. Hence, the implementation rate can exceed 100%) 12.

Case country 8: Indonesia

Indonesia introduced the pentavalent vaccine (DTwP-Hib-HepB) into its National Immunization Program in 201313. According to data from the World Health Organization (WHO), the pentavalent vaccine in Indonesia applies 4-dose schedule administered at 2, 3, 4, and 18 months of age. The hepatitis B vaccine (HepB) requires only a single dose at birth. The measles-rubella (MR) bivalent vaccine is given by a two-dose regimen, administered at 9 and 18 months of age. The inactivated polio vaccine (IPV) is given at 4 and 9 months. The oral polio vaccine (OPV) is given in a total of four doses, consecutively at birth, 1 month, 2 months, and 3 months of age.
