Happy World Immunization Week! To reflect the huge range of amazing people and organisations who will be raising their voices for vaccines over the next few days, this week we have a number of different curators looking after the @Vaccines handle on Twitter. Check out their profiles below, and don’t forget to tune in for their daily updates!

Monday, WHO

The World Health Organization kick off World Immunization Week proceedings on Monday by introducing campaigns and celebrations in honour of vaccination from around the world.

Tuesday, PATH

PATH will be tweeting @Vaccines on Tuesday, marking the intersection of World Immunization Week and World Malaria Day – the perfect opportunity to talk about malaria vaccines! Right now, RTS,S is the malaria vaccine candidate that is farthest along in development globally. Follow @Vaccines to learn about the past, present & future of RTS,S, from early research in the 1980s, to the 2001 public-private partnership to develop the vaccine for infants in sub-Saharan Africa, to more recent trials and the announcement of African pilot studies.

PATH will also be sharing key findings from Connecting the Dots, a digital feature about building next generation immunization supply chains. This World Immunization Week, PATH hopes to bring awareness to immunization supply chains. After all, vaccines only work when supply chains do.

Wednesday, Save the Children

On Wednesday @Vaccines will be curated by Kirsten Mathieson from Save the Children. Kirsten advocates for Universal Health Coverage, to ensure that all children can access essential health services, including immunisation, as part of their right to health. She will be tweeting about the importance of driving more equitable immunisation coverage.

Thursday, *mystery curator*

We can’t tell you much about this yet, so watch @Vaccines on Thursday to find out who will be sharing their vaccine views near the end of World Immunization Week.

Friday, Gates Foundation

Orin Levine, Director of Vaccine Delivery at the Bill & Melinda Gates Foundation will be curating @Vaccines on Friday, 28 April. Inspired by the week’s theme of #VaccinesWork, Orin will focus on the actions needed – from supporting health workers to investing in innovation – to ensure that all children, everywhere have access to life-saving vaccines.
