Covid jab provides strong protection for at least six months post-vaccination

While the jab provides strong protection for up to six months, there was less protection for some vulnerable groups.

The Covid-19 vaccine provides strong protection against severe disease and mortality for at least six months post-vaccination, according to evidence from the Health Information and Quality Authority (Hiqa).

The health authority has published three reviews on the duration of immunity following the jab to inform the work of the National Immunisation Advisory Committee (Niac).
