Bancel, asked about shortages of workers at the Lonza factory at Visp in the Swiss canton of Valais, which has a licence to make ingredients for its COVID-19 vaccine, but was confident that Lonza would close the gap there soon.He also said that Moderna was in talks with the COVAX vaccine-sharing facility which is providing doses to lower income countries, adding: "I hope we are in the final stretch to get an agreement with COVAX."
I'm not surprised that Lonza is having a difficult time staffing its facility. Vaccine manufacturing at Lonza has gotta be very high pressure, and CMOs aren't really known for their great pay*. I suspect that Moderna is asking Lonza to expand, and Lonza is having an understandably tough time keeping pace.

The pay is very competitive, given that they are located somewhat remote (awesome if your into mountaineering though). The major issue at this point is Swiss immigration law, which is based on fixed yearly quotas for foreigners and which has been maxed out rather quickly as you can guess. They are trying to cut the red tape but these sort of things take time anywhere in the world.
