Scientists have discovered that there are certain individuals who appear to be genetically unable to reproduce the virus. There is something in the makeup of their blood cells which makes it impossible for the HIV virus to attach and reproduce. In essence, these individuals are immune because, from a biological point of view, the HIV virus cannot attack them.
Yes some people can. but only if they have already been vaccinated or if they have had smallpox before and survived or if they have the disease cowpox.
Yes, they also deliver an immunity to cowpox and mumps.
Yes, prior to its eradication millions of people died every year from smallpox. Those that survived often had significant scars, both internal and external, for the rest of their lives.
No noone is immune to small pox
I happen to also be immune to small pox. I remember being given the vaccine a bunch of times as a kid and I never got the reaction from it which leads to that circular scar on the upper arm like everybody else around my age did.
Beg to differ, I am naturally immune to smallpox. Doctors who have tested me have told me that I am one in .0001% of the human population who are immune to smallpox.
yes they are
The HIV virus kills the helper T-cells which are part of your immune system.
HIV, human immunodeficiency virus, is the virus that attacks the cells in the immune system that produce antibodies.
Lupus is not a virus, it is a malfunction of the immune system.
Virus
he was immune to that virus because he had gotten it before.
HIV is a retro virus, that infects your immune cells. The virus attaches to CD4 receptors on T-cell (the cells that are part of the immune system.)
Anyone not immune to the virus (not a common virus anymore though)
Weakens their immune systems
Because the immune system attack the dead virus so the next time the virus come into the body thebimmune systek reconize it and attack the virus
None. Swine flu is an illness caused by the pathogen known now as swine flu virus, A-H1N1/09 influenza. The illness contains no immune cells, nor does the virus. Your body responds to the presence of the virus with an immune response that sends your own immune cells to the area of your body where the flu virus has invaded. It is your body's immune cells that enter the "fight" and eventually get rid of the virus by constructing the type of immune cells called antibodies that are a perfect fit to inactivate the specific virus so it can no longer cause cell damage and symptoms of the flu. Your body then remembers the antibodies that worked to inactivate the virus so it can use them in the future if you are ever exposed to that virus again.
