Covid19 vaccines are here to save the day as high rates of SarsCov2 infections around the world continue to exceed hospital capacities. Access to vaccines is essential to prevent severe symptoms from a Covid19 infection in case of exposure to the virus. Fortunately, several vaccines have received emergency use authorization. Now that vaccines are available- many of us have questions. Are the vaccines safe? Are they effective? How do they work in our bodies? A vaccine generates active immunity in a similar way to how the body develops protection when it is infected by a pathogen. Vaccines against SARs-Cov-2, specifically, can be classified by their mechanism of action, which is the way they work to stimulate your immune system.
