The European Medicines Agency's (EMA) leading vaccine expert on Thursday said that data on COVID-19 vaccines tailored for the Omicron variant should be available between April and the start of July, potentially paving the way for approval this summer.
Vaccine makers such as Moderna and Pfizer have begun testing COVID-19 vaccines designed to target Omicron after data showing that two initial COVID-19 vaccine doses provide only partial protection against the variant.
Based on data for Omicron-specific vaccines, the agency will decide on a timeline for the potential granting of approval.
