Vaccines have an agent resembling the virus, micro organism or parasite inflicting the illness, which in case of COVID-19 is the SARS-CoV-2 virus. The vaccine has both a weakened or lifeless microorganism, its toxins or a floor protein. It has the virus’s genetic materials, which might then be learn by the physique to formulate the immune system response.
When the vaccine is injected, the agent goes into the cells of our tissues. Thereafter, it captures the eye of sure ‘dendritic’ cells, which have a selected perform to watch intruders that may have entered the physique. The patrolling cells discover this by no means earlier than seen agent and alarm the physique towards it.
The dendritic cells do that by studying the genetic directions in regards to the virus injected into the physique via the vaccine. Thereafter, the knowledge is replicated for the immune system to learn and react.
