You can also have covid run it's entire course through your system, without ever (EVER) showing symptoms.
The CDC said early on that based on antibody tests, it was likely that more than one hundred TIMES the number of people who were "known" cases, had the virus. Loosely translated for those who don't speak reality:
For every ONE person who knew they had it (testing, symptoms, whatever), there were ONE HUNDRED other people who had it, never knew they had it, and recovered from it just fine. The way the CDC knew that? Those one hundred people had antibodies in their system, that only a person who has recovered would have.
Which begs another question - if we can identify the antibodies...why hasn't big pharma reproduced the antibodies yet, for a TRUE VACCINE????
