During the past month a lot of family and friends I know got an sv anda few of them had all of the symptomssuch as chills, fever, headache, d*, stomach cramps but did notv*. Some of them did not even get n*.


Those who did not v* are not emet either. It's the brain that causes us to v* and I"m wondering if some people areless likely to v* than others due tobiological makeup.
