Professor Sarah Gilbert, the scientist behind the AstraZeneca vaccine, said booster shots were unnecessary for many people.
Professor Gilbert, University of Oxford, on September 10 said that the ability to create immunity after vaccination with AstraZeneca vaccine is still very good, even with the Delta variant. Elderly and immunocompromised individuals may need booster shots, but current two doses of AstraZeneca are sufficient to provide long-term protection for the majority of people.
“We will consider it on a case-by-case basis. Elderly and immunocompromised people will receive additional injections,” she said. “But I don’t think booster shots should be given to everyone. Immunity is still maintained well for a long time for most people.”
The comments made by the leading scientist behind the vaccine AstraZeneca come as the Immunization and Immunization Committee, an advisory council to the UK government, is expected to make recommendations in the coming days on the size of the vaccination program. increase.
British health authorities on September 10 announced Pfizer and AstraZeneca are safe enough to use as booster injections. UK Health Secretary Sajid Javid hopes the booster injection program will start later this month.
Professor Gilbert said the world should prioritize providing more vaccines to countries with limited supplies.
“We need to vaccinate countries where vaccination rates are low,” said Gilbert. “We have to work harder. The first shot has the biggest impact.”
