And that the three month gap is a very good tactic

It’s great isn’t it?

I’ve had the other one, I hope it’s similar

Hurrah, all good news is very welcome!

Great news

I think it’s likely to be. I think this was always going to be the case, they just didn’t have the data to prove it.

Yes, I agree. I heard something on R4 a while ago about the likelihood of some of these things, but as you say, without data ‘nothing is proved.’

Excellent news, though how do they know if no one on the trials were given the 12week dosing plan (as it was only devised very recently) and no one has waited 12 weeks since we first started vaccinations?

I’m guessing some people in the trial have had a 12 week gap? 🤷‍♀️

I read one of the original reports and the Astra zeneca trials did seen to use a variety of timings for the 2nd jab, up to and including 12 weeks. Pfizer only went up to 3-4 weeks though I think. Not sure about anyone else.

New preprint on the efficacy of a single dose of the Oxford/AZ ChAdOx1 nCoV-19 vaccine. 76% efficacy against symptomatic infection from day 22 to day 90 post vaccination in 17,177 trial participants in UK, Brazil and South Africa:

Vaccine efficacy against symptomatic COVID-19 clearly higher with longer interval between first and second dose.

No-one in a population of 12,408 people vaccinated with a single dose of ChAdOx1 nCo-19 was hospitalised with COVID-19 from 22 days after immunisation.

It’s such good news, I can’t wait to have my jab, hopefully if we keep up with 500k jabs a day, in a 100 days all adults will have been vaccinated 😊

Excellent news, which fully vindicates the JCVI’s strategy of vaccinating as many people as possible by having a gap of 12 weeks between doses. The more data we get, the more confidence in the vaccines increases.

Isn’t science wonderful?

Such brilliant news. Hoping the transmission aspect is correct. Does this suggest the 67% reduction is after the first dose?

There were varying gaps in the trials, I remember reading the results published on a government website I think. IIRC, some waited up to 18 weeks for the second dose. They were continually tested for antibodies during those time frames and the numbers just kept increasing over that time period, and were boosted even more after the second jab
