World Immunization Week, which takes place in the last week of April  every year, is an opportunity to remind families and communities how  effective vaccines can be, and to encourage people to take action to  ensure that more children, and increasingly people in other age groups,  are immunized against deadly and debilitating diseases.
 
 Today, immunization averts 2-3 million deaths each year from diseases  such as diphtheria, measles, pertussis, pneumonia, polio, rotavirus  diarrhoea, rubella and tetanus.
 
 One important driver of this progress has been the Expanded Programme on Immunization (EPI), which celebrates its 40th anniversary in May 2014. The EPI has been established in all countries.  At the global level, EPI brings together partners to work towards  ensuring that everyone has the chance to be fully immunized. Priority is  given to some 40 nations where routine immunization coverage is lowest,  and to the districts within those countries where children are least  protected. When EPI was established, just 5 per cent of the world’s  children were receiving basic immunizations. Now this figure stands at  more than  80 per cent.
 
 Yet, 40 years on, the job is still not done. More than 22 million of the  world’s children (about one-fifth of infants) are still not being  immunized with basic vaccines.
 
 This year, with the slogan “Immunization for a healthy future. Know,  Check, Protect”, the World Health Organization and its partners around  the globe are encouraging people to learn more about which vaccines are  needed to prevent deadly illnesses, to check to see if their family’s  immunizations are up- to-date, and to seek out vaccination services so  that all family members are protected.
 
 One way in which we are working with partners to help this happen is by  encouraging use of new mobile and Internet technologies. A number of  countries are now delivering information about vaccination directly to  people’s mobile phones and social media accounts.
 
 Getting reliable information to those who need it is key to increasing  access, and to helping countries implement the Global Vaccine Action  Plan (GVAP) ― endorsed by the World Health Assembly in May 2012. The  Action Plan aims to prevent millions of deaths by 2020 through more  equitable access to existing vaccines for people in all communities.
