The more time between the administering of the two doses of AstraZeneca’s Covid-19 vaccine the better for immune responses in the recipient, new research has confirmed, indicating the earlier approach taken by the Government in this regard could possibly have better results.
At the beginning of June, the gap between the two doses of the AstraZeneca vaccine was cleared for reduction from 12 weeks to eight weeks under updated advice from chief medical officer Dr. Tony Holohan.
This advice was submitted on a fresh recommendation from the National Immunisation Advisory Committee (Niac).
The initial gap between the two doses was 16 weeks.
Previous UK studies have shown that one dose of the AstraZeneca vaccine is only 33 percent effective in protecting against infection by the Delta Covid-19 variant, but that this rises to 60 percent with a second dose.
