Vaccines have likely never made more headlines than they have over the last two years, as the race to develop the COVID-19 vaccine made their importance in ensuring global health security all the more evident. 

But prior to the pandemic, immunizations were already a vital part of not only ensuring health security, but also in saving millions of lives every single year. It is estimated that immunizations prevent 4 to 5 million deaths annually, and they have drastically reduced childhood mortality rates thanks to increased protection against diseases like measles, pneumonia, cholera, and diphtheria.

Still, another 1.5 million deaths could be avoided each year with improved global vaccination coverage, according to the World Health Organization (WHO).

These millions of deaths, caused by vaccine-preventable diseases, are due to lack of access to health care in some parts of the world, as well as the anti-vax movement that stems from misinformation around vaccines. 

And when the pandemic hit, these barriers to vaccine coverage intensified. 

While the usual challenges surrounding delivery, access, and vaccine hesitancy still existed, they were made much worse due to the fact that COVID-19 meant routine immunization programs were forced to come to a halt.

This impacted not only the actual physical delivery of the vaccines, but also the perception around them. Some public health experts now fear that the anti-vax sentiment surrounding the COVID-19 vaccine is causing an increase in hesitancy for routine immunizations, too.

Yet, thanks to organizations like UNICEF, the Global Polio Eradication Initiative, and Gavi, the Vaccine Alliance, health workers from around the world continue to carry out the life-saving work of delivering vaccines.

Because of vaccines, polio cases have decreased by more than 99% and it is on the brink of eradication. Meningitis A epidemics have been controlled and almost eliminated in 26 African “meningitis belt” countries since the introduction of the vaccine in 2010. The global measles mortality rate went down by 73% between 2000 and 2018. The world is seeing more countries implementing the human papillomavirus (HPV) vaccine to help prevent cervical cancer, which caused 342,000 deaths in 2020 alone. 

These wins are not to be understated, but rather replicated, when tackling all vaccine-preventable diseases, including COVID-19. That is why it is so important for the world to continue to invest in immunization efforts at every opportunity. In a few weeks, world leaders have just that — the chance to step up in response to COVID-19 and to prepare for future threats to global health.

The US, Belize, Germany, Indonesia, and Senegal will co-host the second Global COVID-19 Summit on May 12. In the lead-up to the virtual event, the organizers are calling on world leaders, members of civil society, philanthropists, and the private sector to make new commitments to vaccination coverage and global health security.

This World Immunization Week, Global Citizen is calling out the impressive dedication of the health workers around the world that are committed to delivering vaccines quite literally through the jungle, across the desert, up mountains — all around the world.
