ClinConnect Summary

This study is looking at how well antibodies—special proteins in your blood and nose that fight infections—work over time after people get vaccines or treatments for COVID-19 and Monkeypox. Specifically, the researchers want to understand how strong these antibodies are at stopping the virus, which helps protect people from getting sick again. This is especially important for people with weaker immune systems or other health conditions that make infections more dangerous.

Adults who are getting, or plan to get, vaccines or antibody treatments for COVID-19 or Monkeypox may be able to join the study. Participants will need to give their written permission to take part. The study does not include pregnant or breastfeeding women, people under legal protection, or those without social security coverage. If you join, you might have blood and nasal samples taken at different times to measure your antibody levels. The study is not yet open for enrollment but aims to help us better understand how long protection lasts after vaccination or treatment.
