COVID-19 study on vaccinated and unvaccinated adults

Answer a few simple questions digitally without any risk of infection.

Why it's important

Help us fight COVID-19! By sharing your experience during the pandemic, you can help researchers better understand:

The impact of coronavirus vaccines

Side effects and adverse reactions to coronavirus vaccines

Common symptoms of COVID‑19

Frequency and types of testing

Your participation in the eCOV study provides the research community with the data they need to gain useful insights on how to stop the spread of coronavirus. 

Who can participate

The eCOV study is open to anyone over the age of 18. You’re welcome to join regardless of whether or not you received a coronavirus vaccine or tested positive for COVID-19. In fact, we need people with both experiences for a good comparison.

What to expect

Once you’ve created a Data4Life account, we’ll send you the initial eCOV questionnaire. It consists of 21 general health questions and only takes about 5 minutes. 

For the next 8 weeks, we’ll ask you to give us a weekly update. You’ll receive a few follow-up questions each week on the topic of COVID-19, testing, and vaccines.

FAQs

The "COVID-19 study for vaccinated and unvaccinated adults," or eCOV study for short, aims to better understand the impact of COVID-19 vaccines.

Participants are asked to answer digital questions about their experiences during the pandemic. The questions are about COVID-19 symptoms, vaccines, side effects, and testing.

By participating, you can help researchers find new ways to effectively fight coronavirus. Participation is voluntary, and every contribution counts.

The eCOV study is conducted by Data4Life and supported by the Hasso Plattner Foundation in Potsdam. The lead physician of the study is PD Dr. Cornelius Remschmidt, Chief Medical Officer at Data4Life.

The study is open to anyone over the age of 18.

For meaningful results, we need a good representation of the entire population. You’re welcome to participate regardless of whether or not you already had COVID-19, have been vaccinated, or have pre-existing conditions.

Study participation is purely digital. All you have to do is answer a few simple questions. You can do this from the comfort of your own home using your smartphone, tablet, or computer. There are no physical requirements, appointments, or hygiene risks.

Simply create a personal Data4Life account to get started.

The eCov questions relate to both your general health and coronavirus. This includes questions about past COVID-19 infections, vaccination, side effects, and COVID-19 testing.

The initial eCOV questionnaire contains a total of 21 questions. It takes no more than 5 minutes to answer. You will then be asked a few follow-up questions each week. This requires around 2 minutes per week.

Ideally, all participants would participate for at least 8 weeks. You are welcome to continue supporting vaccine research by participating for longer.

All information in your Data4Life account is private and encrypted.

Before researchers see your answers to the eCOV questions, we remove all personal identifiers (e.g. name, email address, and telephone number). This step, called pseudonymization, makes data useful for research without disclosing your identity.

You can find more information about how we maximize the security of your data here.

Yes. The study was extensively reviewed and approved by the ethics committee of the Berlin Chamber of Physicians (Ärztekammer Berlin).

Participating for at least 8 weeks allows researchers to get a full picture and gain important insights on coronavirus infections, tests, and vaccines. If you would like to drop out earlier, you're free to do so at any time. We will do our best to take your previous answers into account.
