The Moderna vaccine appears to be slightly more effective at preventing COVID-19 infection and disease requiring hospitalisation, according to international research. The study matched about 220,000 US veterans who received Pfizer with the same amount who received Moderna and compared the outcomes over six months. The researchers say while the incidence of COVID-19 infection in both cohorts was very low, Pfizer recipients had a 27 per cent higher risk of infection and 70 per cent higher risk of hospitalisation than Moderna recipients.
