One area of particular interest is the spike protein, which is found on the surface of the SARS-CoV-2. Until fairly recently, it was unclear just how long this protein, which plays a crucial role in helping the virus invade our cells and appears capable of causing significant biological harm, can remain in our bodies. Similarly, until recently, it was unclear what if anything can be done to protect against spike protein.   

For most people, COVID-19 symptoms usually last for a few weeks, but for a subset of those infected with the virus, symptoms persist even after the acute phase of the disease. This condition is commonly called "long-COVID." Although estimates vary, it is reported that anywhere from one in ten to one to three people experience symptoms even after 12 weeks of diagnosis.
