| | The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. | | | The United States had administered 302,851,917 doses of COVID-19 vaccines and distributed 371,520,735 doses in the country as of Monday morning, the U.S. Centers for Disease Control and Prevention said. | | | The U.S. Food and Drug Administration has approved Biogen's aducanumab, the first drug to target an underlying cause of Alzheimer's disease. The drug, to be sold under the brand Aduhelm, is the first new approval of an Alzheimer's drug since 2003 and the only treatment designed to slow progression of the mind-robbing disease. | | | The U.S. Food and Drug Administration on Monday approved the first treatment of Alzheimer's disease in nearly two decades, Biogen Inc's (BIIB.O) aducanumab, after a long development process including one large trial that failed to meet its goal. | | | Denmark researchers are using virtual reality to encourage more COVID-19 vaccinations, through a game of maneuvering through a virus-infected crowd in a city square. | | | India's COVID-19 immunisation campaign has struggled to keep pace with demand, especially after a dramatic second wave of infections has left hospitals inundated with patients and killed more than 180,000 people since April. | | | Ontario will loosen COVID-19 restrictions starting June 11, three days ahead of schedule, Premier Doug Ford announced on Monday, as infection rates continue to drift lower after a punishing third wave while vaccinations pick up pace. | | | A top World Health Organization official said on Monday that the WHO cannot compel China to divulge more data on COVID-19's origins, while adding it will propose studies needed to take understanding of where the virus emerged to the "next level". | | | World Health Organization head Tedros Adhanom Ghebreyesus said on Monday he hopes African COVID-19 vaccine manufacturing sites will be identified and some even close to producing by the end of 2021, in the race to deliver more shots to the continent. | | | Glaring COVID-19 vaccine inequality has created a "two-track pandemic" with Western countries protected and poorer nations still exposed, World Health Organization head Tedros Adhanom Ghebreyesus said on Monday, renewing pleas for shot donations. | | | | |
