Immunity against SARS-CoV-2 is acquired in two ways, infection and vaccination. How do they differ? Which is “better”? In comparisons, consideration must be given to rates of infection, transmission, hospitalization, death, and long COVID as well as innate, humoral and cell-mediated immune responses. The only correlate of protection that is currently considered robust is the…

October 6, 2022 In a previous Perspective we considered the relationship between Covid pathology and the gut microbiome. Since then, new studies have shed additional light on the topic. We will consider these new findings, including whether dysregulation of the microbiome might be related to long Covid. INTRODUCTION As we pointed out previously, there is…

September 12, 2022  INTRODUCTION  One of the prominent symptoms of COVID-19, especially long COVID, is called “brain fog”, which includes deficits in attention and concentration, memory, and executive function. This raises the question of the cause. One possibility is that it is only an indirect effect from dysregulated immune activity and/or inflammation. A second possibility is that it is due to direct infection of cell populations within the…

August 2, 2022  INTRODUCTION  Our previous Perspectives focused on the question of whether persistent cryptic expression of virus might be contributory to long COVID. To further consider this question, it may be useful to look at examples of persistence by other viruses. DNA VIRUSES The clearest and most easily understood examples of persistence are found…

These can include fatigue, brain fog, loss of taste and/or smell, and cardiovascular problems. There are two schools of thought on the cause, although…
