- The company said it’s confident the messenger RNA (mRNA) technology it used for the vaccine can stop variants that have popped up in recent weeks, too, Reuters reports.
- The vaccine, mRNA-1273, teaches the immune system to recognize and defeat the coronavirus. So as long as the spike proteins of the virus don’t change, the vaccine should be enough to neutralize it.

- “The vaccines are going to come,” WHO’s chief scientist Dr. Soumya Swaminathan said. “They are going to go to all countries, but meanwhile we mustn’t forget that there are measures that work and ... it’s really important to remind people, both governments as well as individuals, on the responsibilities and the measures that we continue to need to practice ... for the next ... well for the rest of this year at least,” she said.
