The European Medicines Agency (EMA) has backed two separate Covid-19 booster vaccines updated to target the omicron variant of Covid-19 and developed by drugmakers Moderna and BioNTech-Pfizer.
In a statement on Thursday, the EU drug regulator said the two messenger RNA boosters offered protection both against the original version of Covid-19 and the omicron subvariant BA.1, which has since been overtaken globally by later omicron subvariants BA.4 and BA.5.
