Hello everyone,
I'm a physicist so I'm not an expert in immunology etc., but I'm interested in this topic. I read the abstract of this paper (Discussion was very scholarly for me) but still, I'm not sure if I understand it correctly. So I have some questions:
1) Is there exist some possibility that exposure to "ordinary" coronaviruses gives someone some kind of immunity?
2) They wrote they observe "higher frequencies of cross-reactive (p=0.0139)". What does that say? That some immunity is active in about 1.39% of tested people who has negative test?
3) If a person has "higher frequencies..." does it mean the Coronavirus is not inside his bode? Is such a person infectious?
4) What do their results say generally? How many people (in per cent) may have "natural" immunity against Covid?
5) Is there anything else interesting for ordinary people?
Thank you all who will respond.
