World Immunisation Week 2021

This week (24 - 30 April 2021) marks World Immunisation Week. Immunisation is one of the safest and most effective public health interventions in the world and saves between 2 and 3 million lives per year. Last year, the emergence of SARS-CoV-2 brought into sharp focus our need for vaccination, not only to maintain global health, but also to bring economic stability and allow our societies to thrive.

With over 4,200 members around the globe, the BSI represents the voice of researchers who work on vaccines as well as the wider immunology community. Building on the success of our #CelebrateVaccines campaign, we're continuing our mission to strengthen public understanding of how vaccines work and the importance of vaccination. Our new #ExploreVaccines campaign, gives immunologists the spotlight to engage with the public around vaccination by listening and addressing common questions and concerns.

For World Immunisation Week, we have pooled a range of activities and resources related to immunisation and will be posting on social media throughout the week. We would like to encourage everyone to join in promoting the use of safe and effective vaccines to protect people of all ages against COVID-19 and other infectious diseases.

There has never been a more important time to recognise the huge role that vaccines play in keeping our communities safe. Join us online with the #ExploreVaccines hashtag for a week of vaccine engagement and education!

Activities & resources

To begin the week, we're running a special live Q&A with immunologists Dr Jenna Macciochi and Dr Viki Male. Viki is a reproductive immunology scientist at Imperial College London who has been looking at the data on COVID-19 vaccination during pregnancy and Jenna specialises in understanding how nutrition and lifestyle interact with the immune system in health and disease. They will be answering questions from the public about pregnancy, fertility & COVID-19 vaccines on Monday 26 April at 12:30 BST. Head to our Instagram @britsocimm!
