The Moderna coronavirus vaccine may offer very high levels of protection against Covid-19 and there appears to be no evidence efficacy is worse at older ages, primary analysis for the final phase of the study suggests.

Moderna said the analysis of the phase three COVE study of the vaccine candidate, called  mRNA-1273, involving 30,000 participants included 196 cases of Covid-19, of which 30 cases were severe.
