The immune system is the "defense against the infection of your body", according to theCDCAnd he plays a key role after your vaccine. With so many questionsAbout whether the vaccine is safe or not, the agency revealed how exactly it works and why you will want one. Read it to see what happens to your body when you get the Covid-19 vaccine, according to the CDC - and to ensure your health and health of others, do not miss these Without signs that you have already had coronavirus.

"Understand howCOVID vaccine Work, he helps to look at the way in which our body fight the disease, "says the CDC." When germs, such as the virus causingCOVID-19 [Feminine, invade our bodies, they attack and multiply. This invasion, called infection, is what causes a disease. Our immune system uses several tools to combat infection. The blood contains red blood cells that carry oxygen in tissues and organs, as well as white or immune cells, which combat infection. "Keep reading to see how they fight the infection.

"Different types of white blood cells combat infection in different ways," says the CDC:

• "Macrophages are white blood cells that swallow and digest germs and dead or dying cells. Macrophages leave portions behind invading germs called antigens. The body identifies antigens as dangerous and stimulates antibodies to attack them.
• B lymphocytes are defensive white blood cells. They produce antibodies that attack the pieces of the virus left by macrophages.
• T lymphocytes are another type of defensive white blood globe.They attack cells in the body that have already been infected. "These came into play later, keep reading.

"The first time a person is infected with the virus that causes Covid-19, it can take several days or weeks for their bodies to do and use all the combat tools of germs needed to overcome the infection. After The infection, the person the immune system remembers what he has learned about how to protect the body against this disease, "says the CDC." The body keeps some T lymphocytes, called memory cells, which go in Action quickly if the body meets the same virus again. When familiar antigens are detected, B lymphocytes produce antibodies to attack them. The experts still learn how long these memory cells protect a person from the virus that causes Covid-19. "

"Covid-19 vaccines help our bodies develop virus immunity that causes Covid-19 without us doing the disease. Different types of vaccines work in different ways to provide protection, but with all types of vaccines, the Body is left with a provision of "memory 't-lymphocytes as well as lymphocytes B that will remember how to combat this virus in the future."

"It usually takes a few weeks for the body to produce T-lymphocytes and B lymphocytes after vaccination," says the CDC. "Therefore, it is possible that a person can be infected with the virus that causes Covid-19 just before or just after vaccination, then ill ill because the vaccine did not have enough time to offer protection."

"Sometimes, after vaccination, the process of constructed immunity can cause symptoms, such as fever. These symptoms are normal and are a sign that the body builds immunity, "says the CDC.Dr. Anthony FauciThe Chief Medical Officer of the President and Director of the National Allergy Institute and Infectious Diseases felt a pain in his arm. Others have had chills or fatigue. Ato studysays that women feel stronger side effects then men.

There are now three types of main vaccines available or are tested, indicates the CDC:

• "MRNA vaccines"- These of Moderna and Pfizer-" contain virus material that causes Covid-19 that gives our cells the instructions for making a unique inoffensive protein to the virus. Once our cells make copies of the protein, they destroy the genetic material of the vaccine. Our bodies recognize that the protein should not be there and build T cells and B lymphocytes that will remember how to combat the virus that causes Covid-19 if we are infected in the future.
• Protein subunit vaccines include harmless (protein) parts of the Virus that cause Covid-19 instead of the entire germ. Once vaccinated, our immune system recognizes that proteins do not belong to the body and begin to make T cells and T-antibodies. If we are never infected in the future, the memory cells will recognize and fight the virus.
• Vector vaccines"As the kind of Johnson & Johnson-" contains a weakened version of a live virus - a virus different from the one that causes Covid-19-which has genetic material of the virus that causes a COVID-19 insertion (C ' That is to say called a viral vector). Once the viral vector is inside our cells, the genetic material gives cell instructions to make a single protein to the virus that causes Covid-19. By using these instructions, our cells make copies of the protein. This invites our bodies to build T-lymphocytes and B lymphocytes that will remember how to combat this virus if we are infected in the future. "

"All except one of the CVIV-19 vaccines that are currently in phase 3 clinical trials in the United States use two shots," says the CDC. "The first shot starts the protection of construction. A second blow of a few weeks later is necessary to get the most protection that the vaccine has to offer." So get vaccinated when it becomes at your disposal and protecting your life and the lives of others, do not visit any of these35 places you are most likely to catch Covid.
