Vaccines (shots) have been around for a long time, and the science used to create the COVID-19 vaccines (shots) has been studied for years. More details are available at https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety.html. While the COVID-19 vaccine (shot) is new, the science used to create it is not. The COVID-19 vaccines (shots) have been thoroughly tested to make sure they are safe and effective. The US Food and Drug Administration (FDA) authorized the vaccine (shot) under an Emergency Use Authorization (EUA), meaning the vaccine (shot) was proven safe and effective. The vaccine (shot) would not be approved for use if it were harmful or unsafe. The COVID-19 vaccines (shots) took much less time than normal to be released because they were made at the same time as they were being studied and approved, rather than afterward, to save time. They still had the same strict safety measures and reviews as usual. no steps were skipped or shortened.
