Explaining Johnson & Johnson’s, AstraZeneca’s new COVID-19 vaccines
COVID-19 vaccine candidates from Johnson & Johnson and Oxford/AstraZeneca use a viral vector vaccine technology that's been studied since the 1970s.
How do we know this? Because our experts have dedicated their lives to studying how infectious diseases and vaccines work. While the COVID-19 vaccines are new, the mRNA vaccine technology template they use has been studied and refined for decades.
SARS-COV-2 is the strain of coronavirus that causes COVID-19. It's known as a spike protein. Spikes allow a ribonucleic acid (RNA) strand to enter the body, reproduce and kill healthy cells.
The vaccine contains messenger RNA made with the genetic code of spike proteins. When you're injected with the vaccine, this messenger RNA enters your cells and produces a protein to stimulate an immune response, similar to COVID-19.
Now if you encounter the real virus, your body will recognize COVID-19 and is trained to fight it.
An infectious disease specialist breaks down how mRNA vaccine technology works and why scientists and medical experts are confident in its safety.
Here's what we know about how quickly, and how much, protection you'll get in the weeks following your vaccination. Plus, learn why wearing a mask is still recommended no matter how much time has passed since getting the vaccine.
We asked primary care providers in The Ohio State University Wexner Medical Center’s Department of Family and Community Medicine to share what they’re asked most when it comes to the COVID-19 vaccine.
