A flu shot from your local urgent care facility can protect you from the influenza virus. In addition, it can prevent complications from this contagious and dangerous illness. How a flu vaccine acts on your immunity involves a series of events. Here are the details if you want to know the flu shot timeline for your immune system’s protection.
A healthy immune system will fight off any foreign body it detects. That is why meticulous testing occurs each time the patient needs a transplant or a transfusion. The body will need compatible substances. Otherwise, the body will fall into chaos and reject them.
The body’s natural defense has antibodies (soldiers). These soldiers can fight off any infection, while antigens are subparts of a pathogen that trigger the formation of proper antibodies.
A flu vaccine contains part of the flu virus. It is the same virus, but it is a dormant form. This antigen will enter the body through the flu shot. A person’s body has many antibodies. The immune system will recognize the antigen, but it will need time to respond. The immune system will start producing antibodies capable of targeting the new antigen at this stage.
The immune system will take some time to produce enough antibodies. These soldiers will work with the immune system’s components to stop the illness. Antibodies specific to one pathogen cannot protect against another pathogen. This can only happen if there are similarities among the pathogens.
A flu shot contains two strains each of influenza A and B. These dormant strains enter the body and activate the production of antigen-specific antibodies. This is the first reaction. The vaccine will start to degrade after six months.
The body will then produce antibody-producing memory cells. These antibodies will be the long-term army in the body. They will keep on protecting the body against the already registered flu pathogens. The antibody response is more effective than the first reaction if the same set of pathogens invades the body again because of the memory cells.
The memory cells will be ready to release the antibodies by this time, which is important in fighting the antigen or antigens. It means that the individual will have a stronger defense. In addition, exposure to a dangerous pathogen in the future will trigger a quick response from the immune system. This will protect the person against the recurring disease.
People who had the flu shot develop protection against the influenza strains. Other people cannot receive flu shots because of severe flu vaccine allergies and underlying health conditions. These unvaccinated individuals can live with the vaccinated ones. The influenza strains will have difficulty spreading if most of the population already had flu shots. This results in less exposure to harmful flu pathogens. The term for this event is herd immunity.
