First-Dose Coronavirus 2019 Vaccination Coverage among the Residents of Long-Term Care Facilities in France.

BACKGROUND: Long-term care facilities (LTCFs) experienced severe burden from the Coronavirus 2019 (COVID-19), and vaccination against SARS-CoV-2 is a major issue for their residents. OBJECTIVE: The objective of this study was to estimate the vaccination coverage rate among the residents of French LTCFs. METHOD: Participants and settings: 53 medical coordinators surveyed 73 LTCFs during the first-dose vaccination campaign using the BNT162b2 vaccine, conducted by health authorities in January and early February 2021. MEASUREMENTS: in all the residents being in the LTCF at the beginning of the campaign, investigators recorded age, sex, history of clinical or asymptomatic COVID-19, serology for SARS-CoV-2 or severe allergy, current end-of-life situation, infectious or acute disease, refusal of vaccination by the resident or by the representative person of vaccine, and the final status, vaccinated or not. RESULTS: Among the 4,808 residents, the average coverage rate for COVID-19 vaccination was 69%, and 46% of the LTCFs had a coverage rate <70%. Among unvaccinated residents, we observed more frequently a history of COVID-19 or a positive serology for SARS-CoV-2 (44.6 vs. 11.2% among vaccinated residents, p < 0.001), a history of severe allergy (3.7 vs. 0.1%, p < 0.001), end-of-life situation (4.9 vs. 0.3%, p < 0.001), current infectious or acute illness (19.6 vs. 0.3%, p < 0.001), and refusal of vaccination by residents or representative persons (38.9 vs. 0.4%, p < 0.001). CONCLUSIONS: About 3 out of 10 residents remained unvaccinated, and half of the LTCFs had a coverage rate <70%. This suggests that COVID-19 will remain a threat to many LTCFs after the vaccination campaigns.

Smart multisensor kernel.

We describe in this paper a smart multisensor kernel, given the shape of a wriststrap and able to characterise a current physiological state among a number of ones resulting from a previous analysis, and to transmit those results using a radio link. The main advantage of this product is its adaptability. As examples, we describe two applications which are the remote monitoring of elderly people and the sleep staging.
