A single dose of either the Pfizer-BioNTech or Oxford-AstraZeneca vaccines reduces the risk of hospitalization from Covid-19 by more than 80% in people aged over 80, new data from Public Health England (PHE) shows.

A single dose of either the Pfizer-BioNTech or Oxford-AstraZeneca vaccines reduces the risk of hospitalization from Covid-19 by more than 80% in people aged over 80, new data from Public Health England (PHE) shows.

People aged over 70 were also shown to have up to 61% protection against symptomatic disease from the Pfizer-BioNTech vaccine and up to 73% from the Oxford-Astra-Zeneca vaccine.

The new data supports the country’s decision to use both the Pfizer-BioNTech and Oxford-AstraZeneca vaccines at a time when other countries in Europe showed concern about using the AstraZeneca shot in older people.

"It is important to remember that protection is not complete and we don’t yet know how much these vaccines will reduce the risk of you passing Covid-19 onto others," she said.

Data released last week by PHE from studies in health workers found that one dose of the vaccine prevented people from catching asymptomatic Covid-19 by at least 70%, which suggests the vaccines may help to reduce the spread of infection, but more data is needed.

China plans to inoculate 40% of its population with Covid-19 vaccines by the end of June, respiratory disease expert Zhong Nanshan has revealed.

China has only vaccinated 3. 56% of its population — roughly 51 million people — so far, Zhong said.

The first single-dose Covid-19 vaccine has been authorized for use in the United States after advisers to the Centers for Disease Control and Prevention unanimously voted to recommend the Johnson & Johnson shot for Americans 18 and older.

To get there, we need to vaccinate many more people. "
