The scientists found that after the second dose, a wider gap also resulted in higher neutralising antibody levels against the Delta variant and all other variants of concern.īut in this instance antibody levels dropped off between first and second dose – leaving the recipients vulnerable against the Delta variant after one jab. They found that both short (three to four-week) and long (10-week) dosing intervals of the Pfizer vaccine generated strong antibody and T-cell immune responses.īut the longer schedule led to higher antibody levels and a higher proportion of helper T-cells, which according to the researchers supports immune memory. “Unfortunately, I can’t see this virus disappearing so you want to balance that against getting the best protection that you can.”įor the Pitch study, the researchers recruited 503 healthcare workers, 44% (223) of whom previously had Covid-19, and studied the immune responses generated by the Pfizer jab. She added: “I think that eight weeks is about the sweet spot for me, because people do want to get the two vaccine and there is a lot of Delta out there right now. “Also, other factors need to be balanced, vaccine supply, the desire to open up, and so on.” “The decision to put it to eight weeks is really balancing all the wider issues, the pros and cons – two doses is better than one overall. Prof Susanna Duanchie, of the University of Oxford, who is the joint chief investigator in the study, known as Pitch, said: “The original recommendation from JCVI was 12 weeks and this was based on a lot of knowledge from other vaccines that often having a longer interval gives your immune system a chance to make the highest response. See information about COVID-19 vaccine safety and side effects.This was at a time when vaccines were in short supply and preliminary research suggested that widening the gap from the manufacturer-recommended four weeks to 12 increased the immune response.īut in May the guidance was changed to eight weeks as cases associated with the Delta variant continued to rise in the UK.
