The European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) published a joint recommendation last week supporting using a mix of different types of COVID-19 vaccines. This recommendation applies to both the initial dual vaccination and the booster, which is now recommended to be taken after 6 months since the first vaccination.
According to these agencies, there is clear evidence of the benefits that the combination of viral vector vaccines and mRNA vaccines produces very good levels of antibodies against COVID-19 and a higher immune response than using the same vaccine. These recommendations come after 8 months of research, and could make vaccination programmes across Europe much more flexible.
EMA and ECDC continue to urge all EU citizens to get fully vaccinated and to adhere to the recent recommendations on booster vaccination.
