All studies confirm that the use of drugs other than those used for primary vaccination in booster vaccination is safe and effective. This was stated at a briefing by the head of the department of vaccination strategy and health hazards of the European Medicines Agency Marco Cavalieri.
“All studies show that this approach is safe and effective,” he said.
“Available evidence suggests that the use of an mRNA vaccine other than that used in the primary vaccination results in a similar or even stronger immune response than the same vaccine. This includes situations where a vector vaccine was used for the primary vaccination “, – the expert emphasizes.
According to Cavaleri, vaccine manufacturers Comirnaty and Spikevax have already asked the EMA to change the instructions for use to allow the use of drugs as a booster, regardless of which vaccine was used for the main vaccination.
“We are currently reviewing data provided by companies to support these claims,” he said.
