Whoever told you the covid vaccines/shots/jabs or ANY OTHER VACCINE prevents infection, lied to you big time!
I had smallpox vaccine at age 6. Got infected by smallpox at age 9. So conclusive proof vaccine did not prevent infection. Because no vaccine builds a airtight glass enclosure around the body. If someone near you is exuding load of virus material, and you are breathing, the virus will enter your respiratory system and depending on size of it, you can get infected. No way vaccine can stop you from inhaling virus material. The virus does NOT ring a bell as it enters the body. The vaccine's job begins AFTER the virus has made it's presence known by beginning replication and destroying lung tissue. Then using the anti-bodies created by the vaccine, body goes to work fighting the virus. You chances are greatly enhanced to defeat the virus before you end up seriously sick. I do not know why so many posters do not understand basics of vaccine functionality.
