hi. I am not sure how it works. but as you been mentioned abt the vaccine. by my commensense, if someone injected the vaccine. they should have anti/immune to this Cov19 right?
people like me if have this vaccine injected.
I would like to know when the drug takes effect, the way I gonna find it maybe is to buy something like atomo test kit to find out.
also some assumption on my observing.
this week many shopping center, school, been closed. if this gonna last other 6 months. I think it's important to ensure people on these critical place: military/food chain/education/health care etc... have are having immunity.
so if this get worst. I think people who has antibody is more valuable to those who not test positive.
