of previous exposure to common colds. But, no one knows why or where they got that exposure.

exposure to certain specific cold viruses can stimulate a person's T-cells (cells that will 'remember' invading viruses and prompt a very quick bodily reaction to stop the invader) quickly enough that the person will have an asymptomatic response to COVID19 -- IOW, the virus gets beaten back before you get sick -- or the person will have only mild symptoms and then shake off the virus. They conclude by saying their results are still very speculative.

But I may be reading this incorrectly, so it's IMHO.

Dr. fauci referred to it yesterday.

goes from "existing cold germ immunity" to "T-cells that attack COVID too." If they can find out exactly what is happening in all those steps, there's a good chance that they'll be able to develop a vaccine or shot that will at least keep a case of COVID from killing you or damaging you severely. Let's hope!

Trying to keep up. I now wear a shield along with a mask. Looking more like aerosol spray may be more dangerous than any other way of spreading the virus. That along with load and speed has me trying that combination to stay safe. Cant hurt.

Thank you for the information.
