It is normal to have questions about any new medical treatment or vaccines. The COVID-19 vaccines have gone through the same thorough evaluation, clinical trials and independent reviews as every other vaccine or medication. They were able to go through this cycle and be produced and tested more quickly because the U.S. government, many drug and biotech companies and academic institutions all worked together to develop safe and effective vaccines. The trials to test the vaccine were able to enroll children more quickly than other vaccine trials because many parents and children wanted to participate. Although the process was faster because of these reasons, the vaccines went through the same safety and efficacy evaluation as other vaccines and medications.
Additionally, the vaccine uses messenger RNA (mRNA), a technology which has been around for more than 10 years and has already been used as a cancer treatment. This is not a new type of technology, which is one of the reasons that pharmaceutical companies were able to develop the vaccines quickly.
