No serious side effects detected so far in US-approved vaccines

[KSTP-TV News, March 27, 2021] As more people get COVID vaccines, there is more to know about their side effects. Dr. Kevin Best, a family physician at Allina Health, says the COVID-19 vaccines are new, but the concept of inoculation has been around for centuries.

“By nature, the fact that this is a new issue and a new virus, there's no way to have long-term studies about it," Best said. "But we do have information about lots of other vaccinations that have happened in the past. There are some new technology in the vaccine, but at the end of the day, they stimulate your immune system to build antibodies, and that's a mechanism that's been used for hundreds of years."
