Breakthrough COVID19 infections after vaccinations in healthcare and other workers in a chronic care medical facility in New Delhi, India
Open accessAbstract
Background and aims Vaccinations for COVID19 are now open to all adults in India. However, spread of COVID19 infection continues unabated. We aimed to ascertain number of breakthrough COVID19 infections after vaccinations in a chronic care, diabetes-centric healthcare facility.Methods We reviewed rigorously maintained data of vaccinations, health status, symptoms of COVID19 & RT-PCR testing of all staff (doctors, nurses, paramedical workers, and other staff) in our health care facility from January 16, 2021 till date.Results Out of 123 employees, 113 were vaccinated (Covaxin, 28, Covishield, 85). Second dose was completed in 107 (94.7%) and first dose in 6 persons (5.3%). Symptomatic COVD19 infections occurred in 19 persons (16.9%) post any dose of vaccine. Symptomatic breakthrough infections > 14 days after second dose occurred in 15 persons (13.3%). Except one (required hospitalization), all 14 had mild COVID19 disease.Conclusions We report mild symptomatic breakthrough infections as seen in our health care facility. Research in breakthrough infections in India should be extended to other institutions and community to obtain larger data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
