EU health authorities have recommended a “mix-and-match” approach to Covid-19 vaccination, saying that using different jabs during the initial and booster inoculation phases produces “good levels of antibodies.”

In a joint statement, the European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) said that “the combination of viral vector vaccines and mRNA vaccines produces good levels of antibodies against the COVID-19 virus (SARS-CoV-2) and a higher T-cell response than using the same vaccine (homologous vaccination) whether in a primary or booster regimen.”

Using different Covid shots as booster jabs – described by the agencies as a “heterologous vaccination” approach – could be utilized as another means of improving immunity, and might be particularly helpful in providing countries with more flexibility in their inoculation rollouts. (RT)
