With careful jabs in the arms of four healthy volunteers, scientists at the Kaiser Permanente Washington Research Institute in Seattle began an anxiously awaited first-stage study of a potential COVID-19 vaccine developed in record time after the new virus exploded out of China and fanned out across the globe. "We're team coronavirus now," Kaiser Permanente study leader Dr. Lisa Jackson said on the eve of the experiment. "Everyone wants to do what they can in this emergency." The Associated Press observed as the study's first participant, an operations manager at a small tech company, received the injection in an exam room. "We all feel so helpless. This is an amazing opportunity for me to do something," Jennifer Haller, 43, of Seattle said before getting vaccinated.Her two teenagers "think it's cool" that she's taking part in the study. After the injection, she left the exam room with a big smile: ''I'm feeling great." Three others were next in line for a test that will ultimately give 45 volunteers two doses, a month apart. Neal Browning, 46, of BothelL Washington, is a Microsoft network engineer who says his young daughters are proud he volunteered. "Every parent wants their children to look up to them," he said But he's told them not to brag to their friends. "It's other people, too. It's hot just Dad out there." Monday's milestone marked just the beginning of a series of studies in people needed to prove whether the shots are safe and could work. Even if the research goes welL a vaccine would not be available for widespread use for 12 to 18 months, said Dr. Anthony Fauci of the U.S. National Institutes of Health. At a news conference, U.S. President Donald Trump praised how quickly the research had progressed Fauci noted that 65 days have passed since Chinese scientists shared the virus' genetic sequence. He said he believed that was a record for developing a vaccine to test. This vaccine candidate, code-named mRNA-1273, was developed by the NIH and Massachusetts-based biotechnology company Moderna Inc. There are no chance participants could get infected because the shots do not contain the coronavirus itself. It's not the only potential vaccine in the pipeline. Dozens of research groups around the worldare racing to create a vaccine against COVID-19. Another candidate, made by Inovio Pharmaceuticals, is expected to begin its safety study next month in the U.S., China, and South Korea. "We don't know whether this vaccine will induce an immune response or whether it will be safe. That's why we're doing a trial" Jackson stressed "It's not at the stage where it wouldbe possible or prudent to give it to the general population."

McCartney wrote the song, originally titled, "Hey Jules" for John Lennon's son Julian to comfort him during the divorce of his parents. It was nominated for Record of the Year, Song of the Year and Best Pop Performance by a Duo or Group with Vocal at the 1969 GRAMMY Awards.
