Senior medics and experts have urged caution on extending the gap between doses of Covid-19 vaccines, saying a significant benefit to the vaccination programme would be needed to justify it.
Minister for Health Stephen Donnelly has sought the advice of deputy chief medical officer Dr Ronan Glynn and the National Immunisation Advisory Committee (Niac) on the possibility. Research has shown good levels of immunity from a single dose.
