More good news Australia. AstraZeneca/Oxford vaccine more effective with longer dose gap. Efficacy 81% with longer interval of 12 weeks between first and second dose, compared with 55% efficacy up to six-week gap, according to the Lancet. #covidvaccine reuters.com/article/us-hea…
@MJA_Editor Yes, the variable timing was a lucky accident of the Oxford trial (supply & logistics delayed some centres, especially early). Graph below is redrawn from numbers in table 1. pic.twitter.com/Y1Jo9oDgDd
@PaulGlasziou @MJA_Editor Would you rather good protection in 3 months or 3 wks? NHS workers in one trust are been threatened for requesting their second dose earlier. Looking forward to the large US trial with standardized dosing 28 days apart - will provide more confidence than this post hoc analysis.
