From various things I’ve read, the virus doesn’t last that long on a lot of surfaces, depending on type and contiion (heat/humidity etc).
Now they’ve found a lot of hand sanitizers have extremely toxic chemicals in them. Of course that is in addition to the vile fragrances made from petrochemicals and formaldehyde which are toxic in themselves. The main “sanitizing” ingredient that I know of is isopropyl alcohol which is absorbed through the skin, and using on the hands a lot is also unhealthy.
Years ago when researching flu, I found that just washing the hands vigorously gets rid of or kills everything. Even rubbing the hands for 1 to 2 minutes under cold running water washes off all bacteria and viruses.
As far what vaxxes shed (just re-read you question more carefully - duh!) - I really do not understand exactly what it is that vaxes shed. The sciencey stuff is beyond my level of education/brain power to really understand. Has to be re-stated in grade school lingo for me.
BUt motherwit (whatever I may have) tells me that washing hands will get rid of it, to me the worse danger from vax shedding seems to be inhalation. Someone correct me if I am wrong. (and of course masks would likely do nada).
Washing hands has to help. If I heard Dr. Tenpenny correctly, skin-to-skin contact is the most effective way to share the vaxxine gizmos, whatever they are. Soap and alcohol are effective on coronavirus itself because they dissolve the lipid layer around the virus. I don't know what the vulnerabilities are of the Coof-vax spike cootie, other than ivermectin (I think I read somewhere).
