The new Omicron variant is far from the only thing changing about the COVID-19 pandemic. Vaccines, vaccine doses, medical advice concerning vaccines, and the language we use to discuss all of it continue to evolve, so YouGov continues to monitor how we ask people about their vaccination status and what results we’re getting. We’ve tested different kinds of questions and found that question language has only minor effects, but we want to get out ahead of all the changes, especially with boosters, so we’re moving to a longer series of questions that ask for more specifics.
