    Jan 13, 2021 · COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes as well as B-lymphocytes that will remember how to fight ...

    Dec 22, 2020 · Amazingly, not one but two COVID-19 vaccines -- from Pfizer and Moderna, respectively -- are spilling out of the chute within days of each other. The new vaccines work the same way, but they differ somewhat from the conventional ones that have long protected us from measles, yellow fever, smallpox, polio and many other infectious diseases.

    Dec 18, 2020 · A Closer Look at How COVID-19 mRNA Vaccines Work. COVID-19 mRNA vaccines give instructions for our cells to make a harmless piece of what is called the “spike protein.” The spike protein is found on the surface of the virus that causes COVID-19. COVID-19 mRNA vaccines are given in the upper arm muscle.

    Scientists have been researching and working with mRNA vaccine technology for decades. However, the COVID-19 pandemic gave them the unique opportunity to put their knowledge and tools to the test and develop the first working mRNA vaccine. The Pfizer/BioNTech mRNA vaccine is the first COVID-19 vaccine authorized for use in the United States.

    • A Piece of the Coronavirus. The SARS-CoV-2 virus is studded with proteins that it uses to enter human cells. These so-called spike proteins make a tempting target for potential vaccines and treatments.
    • mRNA Inside an Oily Shell. The vaccine uses messenger RNA, genetic material that our cells read to make proteins. The molecule — called mRNA for short — is fragile and would be chopped to pieces by our natural enzymes if it were injected directly into the body.
    • Entering a Cell. After injection, the vaccine particles bump into cells and fuse to them, releasing mRNA. The cell’s molecules read its sequence and build spike proteins.
    • Spotting the Intruder. When a vaccinated cell dies, the debris will contain many spike proteins and protein fragments, which can then be taken up by a type of immune cell called an antigen-presenting cell.

    Currently, several COVID-19 vaccines are in clinical trials. The FDA will review the results of these trials before approving COVID-19 vaccines for use. But because there is an urgent need for COVID-19 vaccines and the FDA's vaccine approval process can take months to years, the FDA will first be giving emergency use authorization to COVID-19 vaccines based on less data than is normally required.
