The world still needs more coronavirus vaccines, but an additional bottleneck has emerged in many low-income countries: They need help getting shots in arms.
Why it matters: Increasing vaccination rates across the world is both a humanitarian necessity and the best way to prevent dangerous new variants from emerging, but it increasingly requires complex problem-solving.
Health officials in the United Kingdom, Italy and Germany announced on Saturday that they've detected the first known cases of the new COVID-19 Omicron variant.

New York Gov. Kathy Hochul on Friday declared a state of emergency amid rising COVID-19 cases and the newly identified Omicron variant of the virus.

As vaccine makers pursue the next generation of COVID-19 vaccines, some are working to develop products that wouldn't require a shot.
