Explain in your own words what happens when a virus gets in your body. Use the following words in your explanation: Vaccine, Antibody, Immune System, Memory Cells.

if the virus enters a body the immune system will try to attack the virus with the antibodies but our body is not prepared to face the virus, if you become infected with it it will bring all the consequences that the virus brings but the memory cells will recognize the virus and if it contracts the virus again the immune system would recognize it and attack it with antibodies prepared for virus. Scientists are investigating for a vaccine that makes a kind of weak version of virus so that the immune system can attack them easier because it will be much weaker than virus so that the memory cells will recognize them so that if you contract the original coronavirus, the immune system would recognize it and attack it with antibodies prepared for virus.
