Many of us have either gotten a COVID-19 vaccine or will be getting one soon, but do you actually understand how the vaccines work?

We've heard over and over again from doctors and scientists that the only way to eradicate the virus is to get vaccinated, but no one really explained how the vaccines actually work, until now.

Thanks to the Yale School of Public Health who just put out a public service announcement explaining the safety and effectiveness of both the Pfizer and Moderna vaccines.

According to a Yale news release and, neither vaccine contains any of the viral material, but use mRNA that causes the body's immune system to create coronavirus antibodies. RNA is temporary genetic information that instructs a cell to make a protein. All vaccines work basically the same way by pretending to be the virus triggering your immune system to do what it does naturally to fight the infection.

The video answers some pertinent questions and concerns people may have about the vaccines and answers question about potential side effect, both short term and long term.

Since the vaccines were created in record time, just about ten months, and since there has never been any other vaccine like this using the mRNA code, it's understandable that people may be a little skeptical. Remember, before this, the fastest any other vaccine was created from start to finish was the mumps vaccine which took four years.

Here's the Yale School of Public Health video, created in four different languages, and explains all the aspects of the vaccines.

While much is still unknown about the coronavirus and the future, what is known is that the currently available vaccines have gone through all three trial phases and are safe and effective. It will be necessary for as many Americans as possible to be vaccinated in order to finally return to some level of pre-pandemic normalcy, and hopefully these 30 answers provided here will help readers get vaccinated as soon they are able.
