Dáil Éireann Debate, Wednesday - 27 January 2021
844. Deputy David Cullinane asked the Minister for Health the current known length of time that immunity is provided by the different Covid-19 vaccines; if it is considered to be an annual vaccination; and if he will make a statement on the matter. [4325/21]
View answerCurrently, because the virus is so novel, there is not enough knowledge on how long the immunity conferred by the authorised vaccines will last after vaccination.
The people vaccinated in the clinical trials for each vaccine will continue to be followed for 2 years to gather more information on the duration of protection.
The scientific community, the manufacturers and regulators will monitor the changes in the virus which causes COVID-19 over time and whether the authorised vaccines can protect people from infection with new variants, or whether a change in vaccine composition is needed, and booster vaccinations.
