A Study in California of vaccinated health care workers at two University of California campuses who received the Pfizer or Moderna vaccines on December 16, 2020, and February 9, 2021.The study pool; 36,600 of 1st doses subjects and 28,000 who had been fully vaccinated (two doses).
Looking at vaccinated well-being care personnel at two College of California campuses, scientists discovered a percentage still tested positive for the virus.
Dr Jocelyn Keehner, an infectious disease fellow at the University of California, San Diego (UCSD) School of Medicine, and her team performed the study under a regime of symptomatic and asymptomatic testing among health care workers at their institutions.
Amongst men and women vaccinated, 379 examined positive after a single day subsequent to their first vaccination dose, with (71%) testing positive inside of the first two weeks after the 1st dose of vaccine.
Also, 37 personnel tested positive just right after receiving two doses, when they are intended to have the highest protection.
The scientists estimated that the comprehensive danger of testing positive for COVID-19 just right after vaccination was about 1% for the care workers, which was larger than the threat noticed within the scientific trials, which were not just restricted to healthcare personnel. However the differences in exposure incidences and younger health worker social circle demographics possibly may have been a contributing factor at play in these results not at play in the clinical trials.
Researchers stated it underscored the essential value of ongoing basic public health measures (masking, physical distancing, every single day symptom screening and frequent testing), even in remarkably vaccinated environments, properly until herd immunity is substantial.
The study was reported in the March issue of the New England Journal of Medicine.
