Secretory IgA (sIgA), which may play an important role in the early defense against SARS-CoV-2 infection, were detected in the eye of COVID-19 patients.

First cases of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in the Dominican Republic (DR) were reported in early 2020.

Abstract Background There are few data on immune correlation of protection from breakthrough Omicron (B.1.1.529) infection in individuals who received booster vaccines.

ObjectivesUnderstanding the incidence and characteristics that influence severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine breakthrough infections (VBIs) is imperative for developing public health policies to mitigate the coronavirus disease of 2019 (COVID-19) pandemic.

This is an analysis of a vaccine breakthrough COVID-19 cluster with an 88% attack rate involving 35 security guards (SGs) of the Teaching Hospital-Peradeniya, Sri Lanka.

Using a cross-sectional study design to assess low saturation of peripheral oxygen (SPO2) risk based on vaccination status, we included patients who were confirmed to have SARS-CoV-2 and were treated at home.

We created an epi-curve and identified the index case (IC).

The study of the effects of SARS-CoV-2 infection and/or vaccination on semen fluid analysis (SFA) parameters is still incomplete.
