Shots that use an inactivated virus to stimulate the immune system might perform differently from others that use messenger RNA, a molecule that directs cells to make antibodies against the virus.

Governments considering booster programs also face logistical hurdles, such as whether to vaccinate everyone or just the elderly and vulnerable."

莫德納聲明:
[“We thank Taiwan for their support in securing this new agreement to supply in 2022 and 2023 our mRNA COVID-19 vaccine and our updated variant booster candidate, if approved,” said Stéphane Bancel, Moderna’s Chief Executive Officer. “We remain committed to making our vaccine available around the world.” ]
