Could be better

Oxford vaccine: preliminary results were ONLY 'encouraging'

The drug has been better tolerated in older people, but has produced a similar immune response in young and older participants

The government has ordered 100 million doses of Oxford vaccine - the largest proportion of the 355 million doses in a vaccine portfolio it has purchased.
The crucial results of phase 3, which will reveal the vaccine's effectiveness in tens of thousands of volunteers in several countries, including the United Kingdom, are expected to be published in a few weeks.
