Is it effective against mutant strains? The results of the AstraZenecom vaccine phase study are public

Britain's AstraZenecom pharmaceutical company confirmed on the 6th, preliminary research data show that AstraZeneta developed a new crown vaccine in South Africa initially found a variant of the new coronavirus mild infection protection effect is "limited."
, however, the vaccine appears to be effective against a new coronavirus originally discovered in the UK, according to researchers at the University of Oxford.
: Variants found in South Africa: Limited effectiveness A joint study by South Africa's Jinshan University and Oxford University shows that the new coronavirus, a variant originally found in South Africa, "severely weakens" the effectiveness of the AstraZeneta vaccine, the Financial Times reported On Thursday.
2,026 people took part in the study, half of whom took part in the control group.
the average age of the participants was 31 years old, and no subjects were admitted to hospital or died.
Responding to the reports, an AstraZeneia spokesman said: "In this small Phase I and Phase II trial, preliminary data show that the vaccine has limited protection for patients with neo-coronary mild disease, mainly due to the B.1.351 variant strain found in South Africa.
spokesman said: 'Given that the vast majority of the subjects are young and healthy adults, it is not possible at this stage to determine the effectiveness of the AstraZenecom vaccine for seriously ill patients, but AstraZenecom is confident that the vaccine will protect seriously ill patients.'
vaccine, developed jointly by AstraZeneta and Oxford University, has been approved in several countries.
spokesman said: "Oxford University and AstraZenecom have begun to improve the vaccine to enable it to respond to this mutant virus.
trials will be accelerated with a view to availability in the fall.
: Seemingly effective in the UK Oxford University confirmed on The 5th that ongoing assessments show that the existing AstraZenecom vaccine is similar to the strain originally found in the UK.
Pollard, a researcher at The University of Oxford's New Crown Vaccine Project, said the data from the UK study showed that "the vaccine is effective not only for the original new coronavirus, but also for B.1.1.7, the new variant virus found in the UK".
the study were taken between October last year and mid-January this year.
, another lead researcher at Oxford University, said: "We have been predicting that as the outbreak continues, the mutant strain will become 'mainstream' and a new version of the vaccine may eventually be needed.
in the British Medical Journal says there are thousands of mutant strains of the new coronavirus, with only a small number of significant changes.
scientists and public health experts at this stage are most concerned about the faster spread of the three mutant strains originally found in the UK, South Africa and Brazil, Reuters reported.
the two studies on the effectiveness of the AstraZeneta vaccine on mutant strains have not yet been published in any peer-reviewed medical journals.
