The European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) have both said there is no urgent need for booster Covid-19 vaccines to be administered.
In a joint statement, both authorities said that evidence on vaccine effectiveness and duration of protection shows that current vaccines are highly effective in preventing against hospitalisation, severe disease and death.
They further said that currently one out of three adults in the EEA over the age of 18 are currently unvaccinated.
“In this situation, the priority now should be to vaccinate all those eligible individuals who have not yet completed their recommended vaccination course,” the statement read.
However, both authorities distinguished between those who are otherwise healthy, and those who have weak immune systems.
“Some studies report that an additional vaccine dose can improve the immune response in immunocompromised individuals, such as organ transplant recipients whose initial responses to vaccination were low. In such cases, the option of administering an additional dose should be considered already now,” they stated.
“Consideration could also be given to providing an additional dose, as a precautionary measure, to older frail individuals, in particular those living in closed settings such as residents of long-term care facilities.”
