This year has been full of bad news because of COVID-19. Now there is good news in the fight against the virus. Scientists made a vaccine. It has a 90 per cent success rate and no serious side effects. A top infectious diseases doctor said: "The results are really quite good, I mean extraordinary."
Health experts say it will be months before we get the vaccine. It must be kept at -80º Celsius. One drug company said: "Today is a great day for...humanity....We are reaching this [important time]...when the world needs it most." Infection rates are rising and hospitals are full, but we are closer to end this global health crisis.
