On Similarities and Differences of HIV and SARS Cov-2; Open Questions Relevant for COVID-19 Disease

Abstract

This paper is written from an educated bio-scientist’ perspective who follows studies about COVID-19 in order to better understand some relevant questions about the disease and vaccination. I first pose myself a question about similarities and differences of SARS CoV-2 and HIV viruses. After the available literature search this idea was soon confirmed. Several papers have appeared where authors discuss similarities and differences between HIV and SARS CoV-2. I later come across some open questions on SARS CoV-2, which do or do not have clear answers. I discuss these questions; among them are some about the current vaccines. In my opinion, the hot questions should be addressed as getting clear answers will bring more understanding of the matter and could help in future endeavors.
