STEP 1 Before taking part

1-1 Explanatory notes
The explanatory notes provide the outline of the research. If you wish to participate in the research having carefully read the notes, please apply in STEP 2.


1-2 Web Questionnaire (first time participants) (If you are participating in the research for the first time, please answer this questionnaire regardless of your affiliation or status.)
Please complete the online web questionnaire by noon on the day of your reservation. Also, please provide your body temperature at the time. The questionnaire can be answered after the consent form is submitted, but in principle, your blood will be collected after this questionnaire has been answered. The answers to the questionnaire are especially important for this research, and we kindly request that you complete the answers. For those who decided to not participate in the research having listened to the explanation, the contents of the questionnaire and information from the application for the research will be deleted without delay.

1-2b Web Questionnaire for medical professionals (second time onwards)
If you are a medical professional and this is your second time or more to have your blood taken, please answer this questionnaire.

1-2c General Web Questionnaire (second time onwards) (currently being prepared)
If you are not a medical professional and it has been a year since your first examine, please answer this questionnaire.


1-3 Consent form
Please complete this form in advance so that the examination process may go smoothly.

1-3b Consent withdrawal form
This is necessary should you wish to withdraw your consent to participate. This is not required at the time of participation.

STEP 2 Application

If you wish to apply, please do so through this page. Please do not share the web address for the form as it may change from time to time. You need your UTokyo Account to apply, and please do not forget to log out when your application is complete. If you have any questions about your UTokyo Account, please ask the person in charge of your department. If the form does not open properly, please check here.

Once you have completed the application, you should receive an e-mail with information needed to make the reservation to have your blood sample taken. If you wish to participate, please make a reservation through the website of the most suitable venue. Additional reservation slots will be added as needed.

If you have not received an e-mail from us even after a week, please let us know. Please note that in rare cases emails may not be received due to typing errors.

STEP 3 Collecting blood

Please come to the designated place at the scheduled time with your university ID. Please note that you may be required to wait a little as the collecting will be done in order.

3-1 The research doctor will verify your ID, confirm your consent and answer any questions you may have.

3-2 The research doctor will check your answers to the web questionnaire.

3-3 A sample of your blood will be collected, completing the process.

STEP 4 Returning of results

Currently, we are ready to return the results after about a month from when the blood was taken. We appreciate your understanding that there may be changes in the estimated return dates due to processing circumstances.

When we are ready to provide the results, there will be post on the website to recruit participants indicating that the results are ready separately for each date that the blood was collected. You can check the results by online reporting system. There is a description of antibody titer in the comment column of your checkup results. Please access the page from here.

We will check the information on your application, the answers to the questionnaire and health check-up information before returning your results, in order to make sure that you meet the requirements as a research participant. If you do not answer the questionnaire, the results will not be returned. As measurements are performed once a certain number of samples have been collected, the results are not returned to us on a daily basis.

Based on the current known and unknown information and the various guidelines on how to respond to the novel coronavirus, we do not think you need to see a medical professional or change your daily life according to this measurement results as long as you have good physical condition. Therefore, we will not be contacting you regarding the results if you do not wish to have the results returned or do not come to collect the results.

STEP 5 Your cooperation in one year’s time.

Please consider rejoining the study in a year’s time. We expect this study to yield important insights, and so we greatly appreciate your cooperation. We would like to request those that are engaged in medical care work at the university, concurrent work or as part of your regular course, provide further blood samples and complete additional questionnaires (for medical professionals) when you start work or transfer to a different division. We also ask that you do the same should you come into contact with a patient infected with the novel coronavirus as part of your work. We would like to evaluate the changes in antibody titers of medical staff and the impact of work-related events (such as patient treatment) on antibody titers. Please be aware that you are not obligated to participate a second time, even if you had previously participated. If you wish to do so again, please participate in the research.

Should you wish to do so, please apply from this page. Please note it may not be possible for everyone to participate due to the number limiting the people who can participate. We will provide an update on the recruitment status through the research introduction and recruitment pages. Please also note that the recruitment may be canceled due to changes in the research plan.
