Immunization averts an estimated 2 million-3 million deaths every year. In 2016, global coverage rates for the third dose of the diphtheria, tetanus-pertussis vaccine (DTP3) and the first dose of measles-containing vaccine (MCV1) reached 86 per cent and 85 per cent, respectively, up from 72 per cent for each in 2000. Despite this increased coverage, about 20 million children did not receive three doses of DTP and about 21 million missed the first dose of MCV. Due to the COVID-19 pandemic in 2020, the gradual progress made in the past years with immunization, faces a huge decline. With highly contagious diseases like measles, this poses a bigger risk to the world's children. However, some of the affected countries have already implemented measures to respond and combat this disruption. By combining health campaigns (for vaccines, deworming pills, bed nets, etc.) communities can receive several services all at the same time instead of one by one. This can increase coverage while minimizing exposure during the pandemic. Another viable route to attain this Target is to accelerate COVID-19 vaccination opportunities to people who are often underserved by community vaccination programmes, for example prisoners. Experts have called for people in prisons to be prioritised for the national COVID-19 vaccination strategy, given their risk profile of underlying chronic conditions, age and living environment. Target 3.c: Increase health financing and support health workforce in developing countries The full text of Target 3.c is: "Substantially increase health financing and the recruitment, development, training and retention of the health workforce in developing countries, especially in the least developed countries and small island developing states." Target 3.c has only one Indicator: Indicator 3.c.1 is the Health worker density and distribution. The joint ITU/WHO initiative "Be Healthy Be Mobile" utilizes mobile technology to help countries combat growing burden of non-communicable diseases by bringing mobile health services to scale within national health systems and providing technical expertise on implementing mobile health interventions. Target 3.d: Improve early warning systems for global health risks The full text of Target 3.d is: "Strengthen the capacity of all countries, in particular developing countries, for early warning, risk reduction and management of national and global health risks." Indicator 3.d.1: International Health Regulations (IHR) capacity and health emergency preparedness Indicator 3.d.2: Percentage of bloodstream infections due to selected antimicrobial resistant organisms. The 2016 IHR review process acknowledged the need to include migration and mobile populations in epidemic
