The more protective our immunity is after being infected by COVID-19, the less likely we will be reinfected. A recent study from Denmark shows that our immune system does a pretty good job, but the vaccination might be a wee-bit better.

You would think that healthcare workers, those in “the business,” would be jumping at getting a COVID-19 vaccine – you would be wrong. Here are a few of the facts.
Most of the COVID-19 analyses and media report “milestones,” or instead use averaging to “smooth out” daily random variation. Data on single days lack a temporal context. But here we consider two topics of particular interest: systematic variations such as weekend effects; and COVID-19 infections that might have resulted from family gatherings on national holidays.
COVID-19 frequently dominates the nightly news, and it’s always there in today’s daily life. Is the pandemic ebbing, or is it still menacing the careless? Charts, tables, and statistics dominate the discussion. Some emphasize counts, some quote short-term percentage changes like a 20% drop. Pictures and statistics tell stories, but with COVID-19, it depends on how you look at them.
“I wear the chain I forged in life,” replied [Morley’s] Ghost. “I made it link by link, and yard by yard.” Our immune system, like those chains, contains our immunologic memories. Ferrets can teach us, that like Morley’s chains, our immunologic memory is forged by experience. Sometimes, a current viral illness may, later on, protect us from a similar viral infection; but we may not be as protected as we hope.
There is no doubt that diabetes is a significant health problem. In an attempt to forestall the onset of this disease, physicians have identified biomarkers that were to identify those most at-risk and begin to institute preventative measures. But new evidence suggests that these biomarkers have little predictive value.
There's a new vaccine in town and all the nut logs and screwballs are blabbering nonsense rumors all over the Internet. Here's one that is especially bad – that the Pfizer/Moderna COVID vaccines can give you COVID. No, they can't. It is physically impossible. Here's why.
No one will argue that we have a serious weight control and obesity issue in the United States and every industrialized country. For the most part, public policies to combat the problem have been failures. To understand the underlying problem, we must first begin with understanding our physiology.
Modeling the COVID-19 pandemic has become a quasi cottage industry, both in creating the models (as well as their subsequent failed predictions and criticisms). A new model takes on the hardest of variables to accurately portray: behavior. Not of the virus, but of its human hosts.
According to the CDC, food allergies continue to be a growing problem for children. Peanut allergy is the number one food allergy among children, and its incidence has increased by 21% since 2010. What happens to our body when we have a peanut allergy, and why are some schools declaring themselves nut-free?
There are numerous opinions about the best way to handle (or perhaps end) the COVID pandemic. They range from more strict lockdowns, to "let's open as quickly as possible" coupled with the hope to keep it in check. A pandemic expert picks the first way. It's very unpopular. Is it even a realistic choice?
A century ago, the Flu Pandemic was bimodal. Its first peak was in late winter of 1917, before returning with vengeance in the fall-winter of 1918. COVID-19, too, has shown a seasonal variation, with its early peak last year and another rise now that seems to be fading away. So, some questions: Where do these viruses go? Do they leave at all? What makes them seasonal? Let’s explore.
