Come back in three months? Long dosage interval ‘ups efficacy’ of AstraZeneca vaccine
The vaccine has also become the first with data suggesting it might reduce transmission of COVID-19
GPs might have to factor in a three-month gap between doses of AstraZeneca’s COVID-19 vaccine after newly published data suggest a longer interval affords greater protection.
The data suggested the vaccine was 82% effective in reducing disease severity with 12 weeks between doses compared with 55% efficacy if the interval was less than six weeks.
