NCT04834869

Brief Summary

This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.

Outcome Measures

Primary Outcomes (2)

  • Local Side Effects

    Dichotomous outcome for the emergence of local side effects (e.g. injection site pain, injection site swelling, and injection site redness)

    0-30 days after the COVID-19 vaccine shot

  • Systemic Side Effects

    Dichotomous outcome for the emergence of systemic side effects (e.g. fever, chills, headache, fatigue, nausea, diarrhea, etc)

    0-30 days after the COVID-19 vaccine shot

Secondary Outcomes (1)

  • Unrecognized Side Effects

    0-30 days after the COVID-19 vaccine shot

Sampling MethodNon-Probability Sample
Study Population

In Phase A, a pragmatic approach will track each target group according to the governmental plan; in most countries, it went from HCW to OA to ST. The sample of Phase B will be pre-identified based on the outcome of Phase A. If ≥ 25% of HCW, 10% of OA and 10% of ST of Phase A showed their interest to join Phase B, no additional recruitment will be required. If \< 25% of HCW, 10% of OA and 10% of ST of Phase A showed their interest in Phase B, additional recruitment will be carried out targeting healthcare workers who will receive booster doses. In case of the emergence of special side effects after booster doses, additional recruitment of healthcare workers will be required.

You may qualify if:

  • HCW, OA and ST who received COVID-19 vaccine.
  • Participating subjects should be at least 18-year-old and able to give their informed consent independently.

You may not qualify if:

  • Non HCW, OA and ST who received the COVID-19.
