Follow-up of COVID-19 Vaccine Response in Strasbourg University Hospitals

Follow-up of COVID-19 Vaccine Response in Strasbourg University Hospitals

Vaccination remains the main promising measure to fight against the COVID-19 pandemic. The presumed efficacy of the vaccines is quite remarkable since it varies between 62 and 95%. There is increasing evidence that sex-specific effects may lead to different outcomes of vaccine safety and efficacy. However, sex-disaggregated data after COVID-19 vaccine are lacking. The first purpose of the study is to determine antibody titers against SARS-CoV-2 spike after COVID-19 vaccination. The secondary purpose is to identify predictor factors of immune response including age, gender and biological factors.

Inclusion Criteria:

- Any person, male or female, over 18 years of age who underwent vaccination and

• anti-SARS-CoV-2 serological test after vaccination

• having already given their consent for their biological resources to be:

  • stored in a biocollection of the Microbiology Technical Platform (PTM) having received an approval from the CPP Est-IV and declared to the Ministry of Education and Research under reference No. DC2009-1002;
  • subsequently reused, as well as the anonymized associated data, for research purposes

Exclusion Criteria:

• Inability to give clear information (person in an emergency, difficulty understanding the subject, etc.)
