Covid-19: Oxford University vaccine shows 70% protection


    The coronavirus vaccine developed by the University of Oxford
    stops 70% of people developing Covid symptoms, a large scale trial
     shows.

    It is both a triumph and a disappointment after vaccines by Pfizer
     and Moderna showed 95% protection.

    However, the Oxford jab is far cheaper, and is easier to store and

    So it will still play a significant role in tackling the pandemic,

    There is also intriguing data that suggests perfecting the dose
    could increase protection up to 90%.

    The Oxford researchers have performed the normally decade-long
    process of developing a vaccine in around 10 months.

    "The announcement today takes us another step closer to the time
    when we can use vaccines to bring an end to the devastation caused
     by [the virus]," said the vaccine's architect Prof Sarah Gilbert.

    The UK government has pre-ordered 100 million doses of the Oxford
    vaccine, enough to immunise 50 million people.

What did the trial show?


    More than 20,000 volunteers were involved, half in the UK, the
    rest in Brazil.


    vaccine and 101 cases in people who received a dummy injection.
    The researchers said it works out at 70% protection.

    When volunteers were given two "high" doses the protection was
    62%, but this rose to 90% when people were given a "low" dose
    followed by a high one. It's not clear why there is a difference.
    "We're really pleased with these results," Prof Andrew Pollard,
    the trial's lead investigator, told the BBC.

    He said the 90% effectiveness data was "intriguing" and would mean
     "we would have a lot more doses to distribute."


When will I get it?

    In the UK there are four million doses ready to go, with another

    But nothing can happen until the vaccine has been approved by
    regulators who will assess the vaccine's safety, effectiveness,
    and that it is manufactured to high standard. This process will

    unprecedented mass immunisation campaign that dwarfs either the
    annual flu or childhood vaccination programmes.

    Care home residents and staff will be first in the queue, followed
     by healthcare workers and the over-85s. The plan is to then work


How does it work?

    The vaccine is a genetically modified common cold virus that used
    to infect chimpanzees.

    It has been altered to stop it causing an infection in people and
    to carry the blueprints for part of the coronavirus, known as the
    spike protein.

    Once these blueprints are inside the body they start the producing
     the coronavirus' spike protein, which the immune system
    recognizes as a threat and tries to squash it.


    When the immune system comes into contact with the virus for real,

Are the results disappointing?

    After Pfizer and Moderna both produced vaccines delivering 95%
    protection from Covid-19, a figure of 70% is relatively
    disappointing.
    However, anything above 50% would have been considered a triumph
    This vaccine can also be stored at fridge temperature, which means
     it can be distributed to every corner of the world, unlike the
    Pfizer/BioNTech and Moderna vaccines, which need to be stored at
    much colder temperatures.

※必需填寫滿20字

共20000人參與實驗，打兩劑疫苗中有30人得到武漢肺炎，
打安慰劑的有101人得到。雖然結果沒有比 Pfizer, Moderna 還好，
但是研究團隊說他們的疫苗成本較低，只需要冷藏保存就好。

    These preliminary data indicate that the vaccine is 70.4%
    effective, with tests on two different dose regimens showing that
    the vaccine was 90% effective if administered at a half dose and
    then at a full dose, or 62% effective if administered in two full
    doses.

另外官方新聞稿說如果第一劑劑量減半，第二劑正常打有 90% 保護力
如果兩劑都用正常劑量則是 62%
