A new vaccine, developed by US company Moderna, has been found to be nearly 95% effective against Covid-19. The results come just a week after similar results from Pfizer. Moderna says it's a "great day", and that they plan to apply for approval to use the vaccine in the next few weeks. Neal Browning, in Seattle in the US, was the second volunteer to receive Moderna's Covid-19 vaccine during the phase one trial in March. (Photo: Neal Browning. Credit: Neal Browning)
