Immune responses to the AstraZeneca Plc Covid-19 vaccine improve with a longer gap of about 10 months between doses, and a third shot can boost antibody levels even further, according to a study.
Extending the gap between the first and second doses increased the level of protective antibodies, according to research from the University of Oxford published Monday. The researchers were also able to show for the first time that a booster given more than six months after the second dose induced a strong response and increased activity against variants.
