Efficacy in adults over 65 years of age, who were at particular risk from coronavirus disease, was over 94%.

Moderna Inc. released the preliminary data for its COVID-19 vaccine on Monday and it showed similar effectiveness.
The better-than-expected data from the two COVID-19 vaccines — both developed with new technology known as “messenger RNA (mRNA)” — had raised hopes for an end to a resurgent coronavirus pandemic that had killed over 1.3 million people globally and caused great damage upon economies and daily life.
However, it would be months before large-scale rollouts start while some groups — including healthcare workers — would be prioritized in the United States for COVID-19 vaccinations this year.
The results came as the coronavirus disease was running rampant in the United States, Europe and elsewhere, placing a vast strain on healthcare systems with a record numbers of new infections and hospitalizations.
