Combining different Covid-19 vaccines. There is the opinion of EU agencies

“Currently known scientific studies show that vaccination against Covid-19 in a system where the targeted vaccine is given first and then the formulation based on mRNA technology is safe and gives a better immune response than a system in which only targeted vaccines are used” – write the European Medicines Agency (EMA) and the European Center for Disease Prevention and Control (ECDC) in joint liaison.

This vaccination schedule can be used for both the initial and booster vaccination cycle. Using this vaccine delivery model could allow European countries more flexibility in their vaccination campaign and, in the event of material shortages, protect as many people as possible from Covid-19 faster.w – put a line under the EMA and ECDC.

European institutions have collected data on different combinations of combination of the two types of vaccines available in the European Union. It has been emphasized that vaccine administration regimens in which the mRNA-based preparation is first taken and then transfected or two mRNA vaccines are mixed together are less well studied than the model in which the vector vaccine is administered first, and the mRNA is administered later.

However, there is sufficient evidence to conclude that it is acceptable – when the state of availability requires it – to administer two different mRNA vaccines – mentioned in the communication. add that Injecting the mRNA vaccine first and then preparing the vector later appears to be less convenient than reverse sequencing.

“But we only have limited data on this vaccination model at the moment,” the journal says.

Two vaccines against the Covid-19 virus, made by companies, have been approved for use across the European Union AstraZeneca and Johnson & JohnsonAs well as the products produced by companies Pfizer iBioN Tech A vaccine for anxiety modern. The last two articles use mRNA technology.

In the published letter, the European Medicines Agency (EMA) and the European Center for Disease Prevention and Control (ECDC) again Urging all EU residents to adopt the full course of immunization against Covid-19 and follow recommendations regarding booster vaccinations.

The European Union is currently seeing an increasing number of infections during the ongoing Covid-19 pandemic, as well as an increase in hospitalizations. Vaccination continues to prevent the serious illness or death of many millions of EU citizens, and data shows that hospitalizations and deaths remain lowest in those member states where vaccination coverage is the highest, reads the EMA and ECDC statement.
