Oxford coronavirus vaccine results leave regulators with 'dilemma', warns scientist
The Oxford vaccine may not be as useful as first thought, after published results showed that high efficacy rates cannot be substantiated. At the end of November, Oxford and AstraZeneca announced they had efficacy rates of 90 per cent when people were given a half dose, followed by a full dose several weeks later. However when people received two full doses, efficacy fell to just 62 per cent, far lower than the mid-90s results shown by Pfizer and Moderna. The results leave regulators with a "dilemma", scientists have warned. The Oxford data is currently being studied by the Medicines and Healthcare products Regulatory Agency (MHRA) which will decide whether to approve the jab. However, new data published in The Lancet on Tuesday has led to fears that the more effective half-dose regime will not be approved. The report showed the half-dose trial only "provides a suggestion" that it would be more effective, and said more research is needed. The half-dose vaccine has also not yet been proven to work in the over-55s, so it may not be useful in the first wave of vaccinations. And even if the two dose regime is approved, the study shows it only plays a small role in preventing transmission, which may make it unsuitable to be rolled out to the general population. Experts said regulators would now be in a quandary about whether to approve the low dose vaccination, or allow it to be used in older people. Dr Simon Clarke, associate professor in cellular microbiology, University of Reading, said: “The report on the successful trial of the Oxford/AstraZeneca presents regulators with something of a dilemma.
