Vaccines This paper says that there is a blood-olfactory barrier (similar to the blood-brain barrier) and that blood-borne antibodies can’t get to the olfactory epithelium (mucous membrane lining). (Note that SARS-CoV-2 can get to the brain via the olfactory bulb. !!) That suggests that we are never going to get to sterilizing immunity (i.e. you… Continue reading week ending 2022-09-22 General
