Not a surprise, really. Since human’s have dealt with the coronavirus, in it’s numerous iterations (a different form or version of something) for a very, very, very long time.
Recall the article - There are more viruses than stars in the universe. Why do only some infect us?
More than a quadrillion quadrillion individual viruses exist on Earth, but most are not poised to hop into humans.Included in this post . If you haven't please enlighten yourself?
Let's get to this latest report:
Personally, I didn't doubt that the immune system would have produced a robust antiviral response. Because it's what our immune systems do if you have a healthy immune system.
While documenting a robust antiviral immune response to SARS-CoV-2, scientists at La Jolla Institute for Immunology have found that the body’s immune system can recognize SARS-CoV-2 in many ways.
People were anxious that COVID-19 doesn’t induce immunity, and reports about people getting re-infected reinforced these concerns, but knowing now that the average person makes a solid immune response should largely put those concerns to rest.”
Good diet, rest, exercise, nutrition can help with a healthy immune system. As well as digging in the dirt. Being out doors. Getting fresh air. Having a healthy mind- not one wracked with fear. Do right by your immune system and it will do right by you!
Additionally the fact that about 80 percent of those known to have been infected were asymptomatic or only mildly symptomatic suggested to me, clearly, the human body, sans vaccine, initiated a good immune response.
And really, that just makes sense!
