Objectives:
A strong COVID-19 vaccine campaign is needed to reach the herd immunity and reduce this pandemic infection.
Study Design:
In the Foch Hospital, France, in February 2021, 451 healthcare workers were vaccinated by a first dose of AstraZeneca vaccine.
Methods:
Adverse effects were reported to our pharmaco-vigilance circuit, by an online and anonymous questionnaire following the first weeks of the vaccinal campaign to healthcare workers.
Results:
Two hundred seventy-four (60.8%) of them reported multiple adverse effects. Main adverse effects reported were feverish state/chills (65.7%), fatigue/physical discomfort (62.4%), arthralgia/muscle pain (61.0%) and fever (44.5%).
Conclusions:
On March 2021 many European countries suspended AstraZeneca vaccine for one week due to safety uncertainty. Thus, confidence in its efficacy is undermined. However, the benefit/risk balance is clearly in favor of vaccination.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
