The COVID-19 pandemic has brought immunology terms that are typically relegated to textbooks into our everyday vernacular. These stories helped us make sense of the ever-evolving science.

Vaccines can’t provide 100% protection, so it’s not a failure or surprise when some vaccinated people get sick with COVID-19. The good news is their cases are much less likely to be severe or fatal.
The COVID-19 vaccines are a smash success. But that doesn’t mean they keep every vaccinated person completely free of the coronavirus.
So far, most vaccines in the US are mRNA vaccines. These represent a new technology and are likely to take over the vaccine world. But how do they work? What are their weaknesses? Five experts explain.
With vaccine shortages looming, experts are debating whether it is important to receive two doses or whether it’s better to give one dose to more people and give a second when the supply is better.
There is now a third vaccine that prevents COVID-19 infections. It isn’t quite as effective as the other two vaccines but it has advantages that may make it the frontrunner.
There are two new COVID-19 vaccines that appear to be more than 90% effective. But what are these vaccines, and how are they different from those used previously?
The results from the phase 1 trial are a promising first step in showing that the mRNA vaccine is a viable candidate, but there are unanswered questions and it is still early in the process.
Results from phase 1 trials of a COVID-19 mRNA vaccine created a burst of optimism. But details the company failed to release suggest it is too early to speculate whether the vaccine is effective.
Traditional vaccines can take years to create. Rather than immunizing people with viral proteins, the new approach gives the molecular instructions that allows the body to make its own vaccine.
