[00:00.04]Drug-maker AstraZeneca said Monday its vaccine
[00:05.72]provided strong protection against COVID-19.
[00:10.24]The two-shot vaccine also stopped hospitalizations and deaths
[00:16.60]for all age groups, including older people.
[00:21.20]The results came from the long-awaited study in the United States.
[00:27.64]In a statement, AstraZeneca said its COVID-19 vaccine
[00:33.32]was 79 percent effective at preventing COVID-19.
[00:39.04]The company also said its vaccine was 100 percent effective
[00:45.08]in stopping severe disease and hospitalization.
[00:50.32]And the vaccine worked across all ethnic groups
[00:54.20]and ages, including older people.
[00:58.32]The U.S. study included more than 30,000 people.
[01:03.44]About 20,000 were given two shots of the vaccine.
[01:08.08]The shots were injected four weeks apart.
[01:12.68]The rest received shots of inactive substance called placebos.
[01:18.48]AstraZeneca said its experts did not find any safety concerns.
[01:25.16]They also found no increased risk of unusual blood system blockages,
[01:30.96]or blood clots, that was a cause for concern in Europe.
[01:36.68]"These findings reconfirm previous results observed," said Ann Falsey.
[01:43.24]She is with the University of Rochester School of Medicine
[01:47.76]and helped lead the study.
[01:50.64]"It's exciting to see similar efficacy results
[01:54.12]in people over 65 for the first time," she said.
[02:00.04]Full information about the study, however, has not been published.
[02:04.80]And no outside experts have reviewed the information.
[02:09.28]The British-Swiss company said Monday
[02:12.52]that it will seek emergency use permission in the U.S.
[02:17.64]AstraZeneca's coronavirus vaccine has been approved
[02:21.68]for emergency use in more than 50 countries.
[02:26.20]When it was approved for emergency use in Britain last December,
[02:30.84]the shot was described as the "vaccine for the world."
[02:35.52]It costs much less than vaccines from Pfizer and Moderna.
[02:41.04]It also does not require extreme cold storage,
[02:45.40]making it easier to use in countries with limited resources.
[02:49.88]The AstraZeneca vaccine is a large part of the United Nations COVAX program.
[02:57.20]The program aims to get COVID-19 vaccines to poorer countries.
[03:03.48]Dr. Paul Hunter is a professor of medicine at the University of East Anglia.
[03:10.28]He said that more information was needed to confirm AstraZeneca's claim
[03:15.92]that the vaccine can stop severe disease and hospitalization.
[03:21.24]He added, however, that the results appeared hopeful.
[03:26.64]"This should add confidence that the vaccine is doing
[03:30.48]what it is most needed for," said Hunter,
[03:33.64]who was not connected to the study.
[03:36.84]Last September, AstraZeneca vaccine drug trials
[03:41.08]were temporarily suspended in both Britain and the U.S.
[03:46.64]The company said a woman in the study
[03:49.28]had developed inflammation in her spine.
[03:53.04]This led to a delay in the U.S. drug trial.
[03:57.00]The drug-maker was slow to report manufacturing problems last October.
[04:03.00]The company and its partner, Britain's University of Oxford,
[04:07.40]then reported unclear results from two different vaccine treatments
[04:12.56]in the British drug trial, which left many uncertain if it was safe and effective.
[04:19.08]Last week, more than 12 countries, mostly in Europe, stopped using the vaccine
[04:25.12]after reports it was linked to unusual blood clots.
[04:29.60]On Thursday, the European Medicines Agency
[04:33.92]said its investigation found the vaccine
[04:37.60]did not raise the risk of blood clots, other than very rare cases.
[04:43.04]France, Germany, Italy and other countries
[04:46.92]started using the AstraZeneca vaccine again on Friday.
[04:52.68]AstraZeneca said it would continue
[04:55.04]to examine the new information from the U.S. study
[04:59.20]before giving it to the FDA in the coming weeks.
[05:03.96]It said the study and its results will soon be published.

END OF TRACK. "END OF TRACK." The two men bowed. "Whoever was that person you were talking to?" she enquired, as soon as they stood together. The took of triumph faded from her eyes, she had grown worn and weary. The roses were wilting on the walls, the lights were mostly down now. Hetty, looking in to see if anything was wanted, found herself driven away almost fiercely. I only saw Master Jervie once when he called at tea time, The year 1747 was opened by measures of restriction. The House of Lords, offended at the publication of the proceedings of the trial of Lord Lovat, summoned the parties to their bar, committed them to prison, and refused to liberate them till they had pledged themselves not to repeat the offence, and had paid very heavy fees. The consequence of this was that the transactions of the Peers were almost entirely suppressed for nearly thirty years from this time, and we draw our knowledge of them chiefly from notes taken by Horace Walpole and Lord Chancellor Hardwicke. What is still more remarkable, the reports of the House of Commons, being taken by stealth, and on the merest sufferance, are of the most meagre kind, sometimes altogether wanting, and the speeches are given uniformly under fictitious names; for to have attributed to Pitt or Pelham their[112] speeches by name would have brought down on the printers the summary vengeance of the House. Many of the members complained bitterly of this breach of the privileges of Parliament, and of "being put into print by low fellows"; but Pelham had the sense to tolerate them, saying, "Let them alone; they make better speeches for us than we can make for ourselves." Altogether, the House of Commons exhibited the most deplorable aspect that can be conceived. The Ministry had pursued Walpole's system of buying up opponents by place, or pension, or secret service money, till there was no life left in the House. Ministers passed their measures without troubling themselves to say much in their behalf; and the opposition dwindled to Sir John Hinde Cotton, now dismissed from office, and a feeble remnant of Jacobites raised but miserable resistance. In vain the Prince of Wales and the secret instigations of Bolingbroke and Doddington stimulated the spirit of discontent; both Houses had degenerated into most silent and insignificant arenas of very commonplace business. "It certainly will be. Miss Widgeon," answered Maria, with strictly "company manners." "One who has never had a brother exposed to the constant dangers of army life can hardly understand how glad we all feel to have Si snatched from the very jaws of death and brung back to us." "Just plug at 'em as you would at a crow, and then go on your way whistlin'?" persisted Harry. "Hurroo!" echoed Hennessey; "that's the ticket." "Come forward, keeper," continued the baron, "and state how these arrows came into your hands!" "Yes." HoMEJULIA京香2018下载
