(Reuters) - Moderna Inc said on Wednesday its experimental COVID-19 vaccine induced immune responses in older adults similar to those in younger participants, offering hope that it will be effective in people considered to be at high risk for severe complications from the coronavirus.
The company is one of the leading contenders in the race to develop a vaccine against the virus that has killed more than 820,000 people worldwide. Its candidate, mRNA-1273, is already in late-stage human trials testing its ability to safely prevent infection.
