A study suggests that peoples immune systems remember COVID-19 for months after recovery. One study published in the journal Immunity of 5882 people who had recovered from covid-19 infection found that antibodies were still present in their blood five to seven months after illness3 This was true for mild and severe cases though people with severe disease.
This triggers an immune response in the body which is the bodys natural way of defending itself. Reese-Willis said the vaccine does not stay in our system forever but that once the code sends the genetic instructions to your immune cells the cells create a protein piece that then gives the immune system the ability to fight off the virus. After the protein is made the cells break down those. This represents the minimum period of protection. Thats about how long it takes your immune system to mount an antibody response to the vaccine. The vaccine will strengthen your immune system by training it to recognise and fight against the virus that causes COVID-19.
