Clinical recovery time for Sars-Cov-2 Infection in healthcare workers with full and booster vaccination

Abstract

The increase of infections at the end of 2021 and January 2022 due to the Omicron variant in Ecuador, raises doubts regarding the effectiveness of booster vaccination, which questions the protection provided by booster vaccination and how often to apply it. A sample of 419 cases is taken and compared with the personnel that have complete (58% with third dose) and incomplete (42%) immunization schedules as of December 2021 and January 2022, and the time of symptomatic recovery after SARS infection is determined afterwards. The results show no difference in the recovery time in patients within the two groups and similar symptoms were observed. It is concluded that, given the results, there is no evidence of the need for a third dose in general, but rather, it would be reasonable to focus the efforts of a second booster only in specific vulnerable populations, thus avoiding unnecessary adverse effects that are becoming more frequent, and even allowing the existing vaccines available in countries where they are really needed.
