British regulators approved the country's first Covid-19 booster vaccine to target two coronaviruses.
Half of the vaccine will be used to target the original variant and the other half will be used to target Omicron. The vaccine, an updated version of Moderna's original Covid vaccine, generated a good immune response in clinical trials.
Dr. June Raine is the chief executive of Britain's Medicines and Healthcare Products Regulatory Agency. The decision was supported by the Commission on Human Medicines.
The U.K. uses the first generation of Covid-19 vaccines to protect against the disease and save lives. As the virus continues to evolve, the bivalent vaccine will help protect us against it.
The side effects were similar to those seen for the original Moderna booster dose, with no serious safety concerns.
The emergence of highly contagious Omicron subvariants this spring have appeared to reduce the protection offered by the Pfizer- BioNTech and Moderna vaccines against Covid hospitalizations. Scientists from the U.S. Centers for Disease Control and Prevention said last month that people are more protected by booster shots. Booster shots should be given to people as soon as possible.
