Please help us understand more about COVID-19 by completing your COVID-19 questionnaire today. It doesn't matter how much or how little you've done in the past - every response matters in the fight against coronavirus.

Children of the 90s is a multi-generational study that’s unique for the breadth and depth of its data, and the information and samples you've given us have already informed more than 2,000 research papers on some of the most pressing health questions of our time, including childhood obesity, air pollution and mental health.

Now, you can really make a difference in the fight against COVID-19. Please fill in your next questionnaire (coming soon) and encourage all your friends and family who are in the study to do the same. Thank you for your support.

It’s never too late to get back in touch, however long it's been since you last took part, and you can choose how little or how much to get involved.
