This year has been full of bad news because of COVID-19. Now, there is good news. There is a breakthrough in the fight against the virus. Scientists from drug companies in the USA and Germany have developed a vaccine against COVID-19. It has a 90 per cent success rate and no serious side effects. The head of the USA's National Institute of Allergy and Infectious Diseases said: "The results are really quite good, I mean extraordinary."

Health experts say it will be months before people can get the vaccine. It must be stored at -80º Celsius. One of the drug companies said: "Today is a great day for science and humanity.…We are reaching this [important time]…when the world needs it most." He said infection rates were rising, hospitals were at full capacity and economies are struggling. He said we were a "significant step closer to help…end…this global health crisis".
