Dear colleagues,
WHO’s interim guidance “Evaluation of COVID-19 vaccine effectiveness” is now available at https://www.who.int/tools/covid-19-vaccine-introduction-toolkit#Evaluation%20of%20COVID-19%20vaccine%20introduction. From the site you’ll find links to the COVID-19 VE guidance, a sample size calculator, and generic protocols. Hopefully these are useful to you or others you know who might be working in this space.
We are still undertaking our scoping exercise to understand who is planning COVID-19 vaccine effectiveness and impact studies, where they are being planned, and the key characteristics of such studies. This information will help WHO to understand the future availability of data to inform global policy and the gaps that need to be filled. We understand that plans are still being made and are subject to change. To help us, if you are planning on doing a COVID-19 vaccine impact or effectiveness study, please fill out this survey (https://forms.gle/xPAs4wdo6xq8Kswq7) with any relevant details. This form will take less than 5 minutes of your time.
Please forward this email to colleagues who might be conducting such studies. Questions can be addressed to [email protected]
Sincerely, Danny Feikin and Minal Patel, Department of Immunization, Vaccines and Biologicals (IVB), World Health Organization
