A widespread booster shots campaign as planned by the UK Government is not required for everyone as immunity against Covid-19 among fully vaccinated people is “lasting well”, the creator of the Oxford University vaccine said on Friday.
Professor Dame Sarah Gilbert, a leading scientist who led the development of the Oxford University/AstraZeneca vaccine — being administered in India as Covidshield — said the elderly and people with weakened immune systems may well require the boosters but other doses should be prioritised for countries with low vaccination rates.
“As the virus spreads between people, it mutates and adapts and evolves, like the Delta variant,” she told ‘The Daily Telegraph’.
