The European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) announced on Tuesday their support for mixing different COVID-19 vaccines in initial vaccinations and booster campaigns.
Why it matters: The announcement comes as several European countries struggle to combat recent surges in COVID-19 cases and amid concerns over the Omicron variant.
Details: The EMA and ECDC said that while research is ongoing, mixing vaccines can "offer flexibility in terms of vaccination options, particularly to reduce the impact on the vaccine rollout should a vaccine not be available for any reason."
- They also said that the evidence available "points towards an acceptable tolerability and enhanced immune responses" with mixing vaccines.
- "To avoid a resurgence of cases with a possible increase in [hospitalizations] and deaths, EMA and ECDC urge citizens to follow advice at national and European level to protect themselves, and the wider community," they added.
The big picture: The EMA and ECDC noted that several EU member states have already approved the mixing of COVID vaccines.
- The Centers for Disease Control and Prevention in October backed mixing vaccines in booster campaigns in the U.S.
