What is the dosing that has been approved for the Oxford Astra Zeneca vaccine?

[spearly]

Hi, sorry if this has been done to death, but i am so confused regarding the effectiveness of this particular jab. Results indicate between 62%-90% effectiveness depending on dosing, but I am unsure which dosing I received and therefore the expected efficacy of my jab. Can anyone clarify please?

Hi. This Guardian article which quotes the head of the vaccine trial Prof Sarah Gilbert is a good read.

Prof Sarah Gilbert of Oxford University’s Jenner Institute, who led the research, told the Guardian that people in both dose groups were protected in the trials from severe illness after just one jab.
“I have no qualms about using the high dose/high dose regimen, which is what the majority of people in the trial have had,” she said.
“It’s really important to note that within 21 days of the first vaccination, nobody was admitted to hospital with Covid or had severe Covid and that’s just after one dose – that’s after any one dose in these trials – no admissions to hospital, and that’s a really major result for public health benefits.”
