Moderna Covid vaccine spurs ‘strong immune response, no serious side-effect’ in older adults

A phase 1 investigational trial has revealed that the Covid-19 vaccine developed by US-based pharmaceutical company Moderna elicited a strong immune response in older adults with no serious adverse effects, a study has claimed. The vaccine, called mRNA-1273, is being developed by Moderna in partnership with the US government’s National Institutes of Health (NIH). For the trial, 40 adults over the age of 56 were inoculated with the vaccine.
