Protection against SARS-CoV-2 highest after infection-acquired immunity boosted with vaccination in health care workers

1. SARS-CoV-2 infection-acquired immunity waned after 1 year, but immune protection remained high beyond 1 year in those boosted with vaccination. Evidence Rating Level: 2 (Good) Study Rundown: The effectiveness and duration of immune protection following SARS-CoV-2 vaccination or infection remains contested and pertinent to ongoing vaccination strategies. In this prospective study named the SARS-CoV-2 … Read more

Researchers investigate IgG antibodies against Mtb proteins in an Asian elephant cured of tuberculosis

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb); the leading cause of human death due to a single pathogen before the emergence of SARS-CoV-2. In elephants, the infections and deaths with TB have been reported worldwide, and elephant-to-human transmission has also been reported. Therefore, elephant TB is a concern for both conservation … Read more

The potential impact of oral vaccination against COVID-19 is a transmission to naïve individuals studied in a hamster infection model

A recent article published in Science Translational Medicine demonstrated that mucosally delivered adenovirus type 5 (Ad5) -based coronavirus disease 2019 (COVID-19) vaccination minimized COVID-19 transmission and severity. Study: Adenovirus type 5 SARS-CoV-2 vaccines delivered orally or intranasally reduced disease severity and transmission in a hamster model.

Effectiveness of BNT162b2 third dose against Omicron-associated severe disease

In a recent study posted to the medRxiv* preprint server, researchers analyzed the effectiveness of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) BNT162b2 third vaccine dose against SARS-CoV-2 Omicron-induced severe infection nearly seven months post-vaccination. Study: Protection against omicron severe disease 0-7 months after BNT162b2 booster. Image Credit: Background Following an increase in … Read more

Evidence of croup associated with SARS-CoV-2

Croup, inflammation of the subglottic upper airway mucosa manifest as respiratory distress airflow obstruction in children. In addition, it is associated with epithelial-level edema, and now emergency department (ED) administrations occur due to an acute viral infection.

Approximately 13% of hospitalized COVID patients have severe neurologic symptoms

It has been established that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes dysfunction throughout the body, including the nervous system. Even in patients with moderate acute disease, neurological symptoms may be encountered. In some cases, these manifestations may persist due to long-haul coronavirus disease, also known as long-COVID. Case series, single health system … Read more
