'Safe and effective' booster dose as early as three months after second injection, says EMA

The European Medicines Agency says booster doses can be given only three months after the last dose

The third dose of the Covid-19 vaccine, or booster, will be relevant as soon as three months after the last injection according to a statement issued by the European Medicines Agency (EMA) on Thursday, December 9. So far, she had recommended waiting six months.

“While the current recommendation is to preferably give boosters after six months, currently available data support the safe and effective administration of a booster dose as early as three months after the end of the primary vaccination if there is also an interval. From a public health point of view,” said Marco Cavalieri, head of vaccine strategy at this Amsterdam-based agency.

‘low’ immune response

The interval between doses of the coronavirus vaccine can be shorter than expected. The EMA’s announcement comes the day after a Senate hearing of the head of the Scientific Council, Jean-François Delfraissy.

The professor also pointed out the importance of the booster dose that would increase the immune response of the vaccinated person. He also indicated that it is likely that we will soon need a “fourth dose” of anti-Covid-19.
