Frequently asked questions
Concise answers about CTI, its evidence, its independence and its work for European decision-makers.
About the initiative
What is the COVID Transition Initiative?
The COVID Transition Initiative is an informal, independent, multi-stakeholder, pan-European group of experts, patient advocates and policymakers. It turns expert insight into evidence-based guidance for decision-makers managing COVID-19 as an ongoing public-health challenge. Learn more about CTI.
What are CTI’s priorities?
CTI works across three connected priorities: Awareness, Adoption and Adaptability. Together they address vaccination decisions, visibility of disease burden and coverage, and the resilience of immunisation systems. Explore the three priorities.
Is CTI independent?
Yes. CTI’s content and recommendations remain the independent opinions and responsibility of its group members. Funding does not determine the initiative’s conclusions. Read about governance and independence.
How is CTI funded?
CTI was initiated and made possible by financial support from Sanofi. Its positions and recommendations remain the independent responsibility of CTI members.
COVID-19 evidence
Does COVID-19 still create a significant health burden in Europe?
Yes. CTI’s evidence review highlights continuing hospital mortality, longer-term cardiovascular risks and under-reporting as testing and surveillance have declined. Review the evidence on disease burden.
Does COVID-19 vaccination still provide protection?
Yes. The evidence presented by CTI indicates that vaccination continues to protect against symptomatic disease, hospitalisation and death, although protection wanes over time and uptake remains low in many higher-risk groups. Review the vaccination evidence.
Does a vaccine need to match the circulating strain exactly?
The evidence reviewed by CTI indicates that exact strain matching is not essential for public-health benefit. Closely related vaccine targets can provide similar real-world protection, supporting broader lineage-level updates. Review the strain-selection evidence.
Does CTI provide personal medical advice?
No. CTI publishes general scientific and policy information. This website is not a substitute for diagnosis, treatment or advice from a qualified healthcare professional. See the scientific and medical disclaimer.
Using CTI resources
Where can policymakers find CTI recommendations?
Policymakers can use CTI’s publications, priority pages and Data and Evidence hub to find concise evidence and recommendations intended for decision-making.
How can journalists contact CTI experts?
