vaccines, which both revealed similarly promising results of around 95 per cent effectiveness last week.
The effectiveness drops to 62 per cent when given as two full doses at least one month apart, to give a combined average efficacy of 70 per cent - which experts say is more than most flu jabs. The vaccine - called ChAdOx1 nCoV-19 - uses a harmless, weakened version of a common virus which causes a cold in chimpanzees.
Prof Pollard told the BBC Radio 4 Today programme that it was important to begin mass vaccinations as soon as possible. "If that is right, we might be able to halt the virus in its tracks and stop transmitting between people." This induces an immune response, priming the immune system to attack coronavirus if it infects the body.Conventional vaccines are produced using weakened forms of the virus, but mRNAs use only the virus's genetic code.These antigens are recognised by the immune system and prepare it to fight coronavirus.
Another jab from Moderna, of which the UK has five million doses on order, is 95 per cent effective, according to trial data. She said she expected that to translate into four million finished vaccine doses by the end of 2020, and 40 million finished doses by the end of Q1 next year.THE government has ordered 350million doses of Covid-19 vaccine, with some ready to roll out by December 1.
Currently in phase-3 trials in the UK, USA, South Africa, Japan, Brazil and Kenya, more than 50,000 test patients have been given the vaccine. Early reviews have shown it to be safe. Prevents Covid-19 infection by targeting the virus’s “spike protein”, effectively disabling it before it can cause any damage.
The sample is way way to small to judge its 90%
🤦♂️🤦♂️🤦♂️
how did that happen?...im so surprised🤡
Chance favors the prepared mind.

😂😂😂 and they want people to trust the vaccine
Sometimes that how these things happen. Is the Sun unhappy with the outcome or just stirring it as per usual.
⁉️
And that is the reason I don’t want it . All been rushed and incorrect information
What an absolute nightmare of wording on your part, you make it seem like the effectiveness of the vaccine is down to luck which it isn’t. They just found the right doses by LUCK. Pure clickbait
Before people criticise this too much, does it even matter how as long as the end game is reached? Many historical scientific discoveries were found by error and pure luck FFS! Penicillin for starters, then there’s the microwaves, x-rays, the pacemaker the list is endless.
