The European Medicines Agency (EMA) has supported this Wednesday the booster injection with the single-dose vaccine of the covid-19 from Janssen, at least two months after the first dose and in adults over 18 years of age.
The EMA also explains that a booster dose with Janssen can be given after two doses of one of the mRNA vaccines licensed in the European Union (EU), Pfizer and Moderna.
