Covid-19 Vaccine, the Immune System and CDC. How could we better understand how COVID-19 vaccines actually work? We must look at how our bodies will respond to these particular vaccines. When we are exposed to germs like the virus that causes COVID-19, it could attack and multiply. This invasion is what we refer to as an infection or what causes this illness. Our immune system then battles by using many tools to fight the infection off, while also carrying oxygen to the tissues and organs, and white or immune cells, which fight off infection. White blood cells can fight off infections in different ways; Macrophages, which are white blood cells that ingest and digest the germs and dying cells and leave behind parts of the antigens which are the invading germs. https://www.EpiLift.com
To understand how COVID-19 vaccines work, it helps to first look at how our bodies fight illness. When germs, such as the virus that causes COVID-19, invade our bodies, they attack and multiply. This invasion, called an infection, is what causes illness. Our immune system uses several tools to fight infection. Blood contains red cells, which carry oxygen to tissues and organs, and white or immune cells, which fight infection. Different types of white blood cells fight infection in different ways. Macrophages which are white blood cells that digest germs and dead cells, leaving behind antigens. The body determines that antigens are dangerous, therefore, stimulating antibodies to fight them off. B-Lymphocytes are referred to as defensive white blood cells which produce antibodies that attack pieces of virus that has been left behind by the macrophages. T-lymphocytes is another defensive white blood cell that attacks the cells in the body that have already been infected.
The body could take up to several weeks to use necessary germ fighting tools to overcome the infection when they are infected with the virus that causes COVID-19. The person’s immune system will remember what it learned to fight off and protect against the disease after they have battled the infection. T-lymphocyte are called memory cells, which go to action quickly if the body begins the fight the same virus again. When the body detects the same antigens, the B-lymphocytes will produce antibodies necessary to attack them. The CDC reported that experts are still learning how the memory cells protect against the actual virus that causes COVID-19 https://www.cdc.gov/
COVID-19 Vaccines and how they Work
COVID-19 vaccines help our body to develop an immunity to the virus that causes COVID-19 without having the illness. Each vaccine works differently in a sense of protection. Each vaccine supplies a memory T-lymphocyte and a B-lymphocyte that remembers how to fight off the virus in the future. It could take about 3 weeks for your body to produce T-lymphocytes and B-lymphocytes after you receive the vaccination. It is also possible that the person could get the virus that causes COVID-19 before or after the vaccination due to it not having enough time in your system in order to protect you. The vaccination could also cause symptoms like a fever while in the process of building immunity, which is normal.
At this time, there are 3 main types of COVID-19 vaccines that undergoing phase 3 clinical trials in the USA. Each vaccine will work to prompt our body to recognize and protect us from the virus that causes COVID-19, while none of them will have the ability to give you COVID-19.
mRNA vaccines will include a material from the virus that causes COVID-19, directing our cells with instructions on how to make a protein that is harmless and unique to the virus. After it makes a copy of the protein, it will destroy the genetic material from the vaccine, while acknowledging that the protein should not be there and will build T-lymphocytes and B-lymphocytes that remember how to fight off the virus if we are infected any time in the future.
Protein subunit vaccines consist of protein pieces that are harmless which come from the virus itself, not the germ. When you get vaccinated, the immune system becomes aware that the proteins don’t belong in the body, where it then starts making T-lymphocytes and antibodies. If ever infected in the future, the memory cells will fight the virus due to recognition https://epilift.com/covid-19-vaccine…stem-and-the-cdc/
Vector vaccines include a weakened version of a live virus which is different from the one that causes COVID-19. It has the genetic material from the virus that causes COVID-19, which is referred to as the viral vector. When the viral vector is inside of our cells, the genetic material lets the cells know to make a protein that is different to the virus that causes COVID-19. When using these instructions, our cells then make copies of the protein. Our bodies are then prompted to build T-lymphocytes and B-lymphocytes that remember how to fight the virus that we become infected with in the future https://epilift.com/covid-19-vaccine…stem-and-the-cdc/
Majority of COVID-19 Vaccines need more than One Shot
The COVID-19 vaccines that are in Phase 3 trials, require 2 shots in the USA. Covid-19 Vaccine; the first shot builds your protection and all but one of the COVID-19 vaccines that are currently in Phase 3 clinical trials in the United States use two shots. The first shot starts building protection. A second shot a few weeks later is needed to get the most protection the vaccine has to offer. One vaccine in Phase 3 clinical trials only needs one shot. So, while this door and conversation continue to open up, it’s important to work on building trust with the new COVID-19 vaccines. https://www.EpiLift.com.
