After recent studies done, it was discovered that up to half of the world's population may have a natural immunity to the Covid virus, without ever being exposed. The hypothesis based on the data states that 35%-50% of the world is immune. In some regions, 25% of the population tested have antibody prevalence. Based on this data, we are slowly looking at reaching herd immunity, which is 60%-80% of the population. Certain parts of the world have lower rates than others, and this may be because of the natural immunity. Other studies have found links to Covid-19 being higher in people who had lower vitamin D levels in their blood. Though this is unlikely to be a cure, Having higher levels of vitamin D makes individuals less susceptible to the disease.
