Intense efforts have been set to describe clinical and epidemiological features to guide both the interruption of transmission, prevention and treatment. These emergency efforts have been resource consuming, affecting human and economical capacities worldwide, as well as a potential impact on other research and on the quality of everyday healthcare activities. Needless to say the effect this sudden overload of work and resources can have over preventive immunization activities. According to data collected by the World Health Organization (WHO), UNICEF, Global Alliance for Vaccines and Immunization (Gavi) and the Sabin Vaccine Institute, provision of routine immunization services is substantially hindered in at least 68 countries and is likely to affect approximately 80 million children under the age of 1 living in these countries.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">1</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Disruption of immunization services around the world puts children at risk of diseases like diphtheria, measles and polio. Efforts have to be deployed to help maintain immunization programs and mitigate the impact of the pandemic, especially in lower-income countries. The Covid-19 pandemic has turned on an alert on how much collective health depends on the responsibility of each individual and also on how important the role of vaccines is to keep global population safe and healthy.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Since March 2020, routine childhood immunization services have been disrupted on a global scale in a way that has not been ever seen since expanded programs on immunization (EPI) in the 1970s were implemented. More than half (53%) of the 129 countries where data were available reported moderate-to-severe disruptions, or a total suspension of vaccination services during March–April 2020. The reasons for disrupted services vary. Some parents are reluctant to leave home because of restrictions on movement, lack of information or because they fear infection with SARS CoV-2 virus. Also, many health workers are unavailable because of restrictions on travel, or redeployment to Covid-19 response duties, as well as a lack of protective equipment.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">2</span></a></p><p id="par0025" class="elsevierStylePara elsevierViewall">The progress achieved worldwide for polio eradication is now under threat, risking the resurgence of the disease even though 2 wild polioviruses have been already eradicated. On the 25th of March, the Global Polio Eradication Initiative (GPEI) circulated the first update of the interim guide to help ensure continuity of the program's operations in the context of the Covid-19 pandemic, as well as its support to the pandemic response while also ensuring the safety of its personnel and the communities it works with. SARS CoV-2 transmission will likely continue worldwide in multiple overlapping waves throughout 2020 and, possibly 2021 until sufficient herd immunity to the virus is achieved either through populations’ exposure to the virus or mass vaccination. Until that happens, countries will focus on achieving containment of transmission keeping it at a low level whilst enabling a “new normality” of economic and social life.</p><p id="par0030" class="elsevierStylePara elsevierViewall">In late March, concerned that mass gatherings for vaccination campaigns would enhance transmission of Covid-19, WHO recommended countries to temporarily suspend preventive campaigns while assessments of risk, and effective measures for reducing Covid-19 transmission were established.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">3</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">Many countries have temporarily and justifiably suspended preventive mass vaccination campaigns against diseases like cholera, measles, meningitis, polio, tetanus, typhoid and yellow fever, due to risk of transmission and the need to maintain physical distancing during the early stages of the Covid-19 pandemic.</p><p id="par0040" class="elsevierStylePara elsevierViewall">Measles and polio vaccination campaigns, in particular, have been badly hit, with measles campaigns suspended in 27 countries and polio campaigns put on hold in 38 countries. At least 24 million people in 21 Gavi-supported lower income countries are at risk of missing out on vaccines against polio, measles, typhoid, yellow fever, cholera, rotavirus, HPV, meningitis A and rubella due to postponed campaigns and introductions of new vaccines<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">3</span></a> (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia><p id="par0045" class="elsevierStylePara elsevierViewall">WHO has since monitored the situation and has now issued advice to help countries determine how and when to resume mass vaccination campaigns.

Of course a Covid-19 vaccine is indeed eagerly expected but in no case must it despise the benefits all other vaccines have achieved to improve community health. It is a must to alert healthcare professionals of the need to maintain high uptake of routine schedule vaccines for the preservation of the well-being of the population especially when it is faced by this unprecedented pandemic threat.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "multimedia" => array:1 [ 0 => array:8 [ "identificador" => "tbl0005" "etiqueta" => "Table 1" "tipo" => "MULTIMEDIATABLA" "mostrarFloat" => true "mostrarDisplay" => false "detalles" => array:1 [ 0 => array:3 [ "identificador" => "at1" "detalle" => "Table " "rol" => "short" ] ] "tabla" => array:1 [ "tablatextoimagen" => array:1 [ 0 => array:2 [ "tabla" => array:1 [ 0 => """ <table border="0" frame="\n \t\t\t\t\tvoid\n \t\t\t\t" class=""><thead title="thead"><tr title="table-row"><th class="td" title="\n \t\t\t\t\ttable-head\n \t\t\t\t " align="left" valign="\n \t\t\t\t\ttop\n \t\t\t\t" scope="col" style="border-bottom: 2px solid black">Vaccination campaigns \t\t\t\t\t\t\n \t\t\t\t\t\t</th><th class="td" title="\n \t\t\t\t\ttable-head\n \t\t\t\t " align="center" valign="\n \t\t\t\t\ttop\n \t\t\t\t" scope="col" style="border-bottom: 2px solid black">Total number of countries with postponed campaigns as of 15 May \t\t\t\t\t\t\n \t\t\t\t\t\t</th></tr></thead><tbody title="tbody"><tr title="table-row"><td class="td-with-role" title="\n \t\t\t\t\ttable-entry\n \t\t\t\t ;
