Vaccine-associated enhanced respiratory disease (VAERD), or simply enhanced respiratory disease (ERD), is an adverse event where an exacerbated course of respiratory disease occurs with higher incidence in the vaccinated population than in the control group. It is a barrier against vaccine development that can lead to its failure.
While the acronyms are similar, reactive airway disease (RAD) and reactive airways dysfunction syndrome (RADS) are not the same. [1]Reactive airways dysfunction syndrome was first identified by Stuart M. Brooks and colleagues in 1985 as an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke.
The reasoning is because in the 20-29 age range the benefits to individual of vaccination were less as their likelihood of harm from COVID‑19 is less and closer to the potential risk of harm from the vaccine (at a medium exposure risk with COVID‑19 infection cases running at a rate of 60 per 100,000).
High flow oxygen may be harmful in those with an acute exacerbation of COPD. In the prehospital environment those given high flow O 2 rather than titrating their O 2 saturations to 88% to 92% had worse outcomes. [14] In specific circumstances high flow oxygen however can be beneficial. [15] Antibiotics and steroids appear useful in mild to ...
A January 2024 study by the CDC found that staying up to date on the vaccines could reduce the risk of strokes, blood clots and heart attacks related to COVID-19 in people aged 65 years or older or with a condition that makes them more vulnerable to said conditions.
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
The World Health Organization has reported that, in 2021, "Lower respiratory infections remained the world’s most deadly communicable disease other than COVID-19, ranked as the fifth leading cause of death." However, the number of deaths caused has decreased by around 13% from 2000 to 2021.
The COVID‑19 vaccines are widely credited for their role in reducing the spread of COVID‑19 and reducing the severity and death caused by COVID‑19. [ 210 ] [ 213 ] Many countries implemented phased distribution plans that prioritized those at highest risk of complications, such as the elderly, and those at high risk of exposure and ...
