The US biotechnology company Moderna has reported positive study results with a new corona vaccine that is intended to protect against both the original virus form and the omicron variant.

According to the company, 814 adults who had already received three doses of Moderna’s original corona vaccine Spikevax took part in the study. About half got a fourth dose of Spikevax, the second group got a dose of the new so-called bivalent vaccine against both variants.

The study participants who received the new bivalent vaccine had an average level of antibodies against the omicron variant that was about 75 percent higher than in the comparison group. Their immune protection against the earlier corona variants was also slightly higher than in the group that had received a fourth dose of Spikevax.

“We are thrilled,” said Moderna boss St├ęphane Bancel about the study result. He expects that the new corona vaccine will be his company’s favorite for an application for approval for a corona booster vaccination for the coming autumn. “We want to be ready for delivery as early as August,” Bancel announced in an interview with investors.

Moderna acknowledged that the bivalent vaccine will generate slightly fewer antibodies against the new subtypes of omicron that are now circulating. However, the protective effect is still higher than with a booster vaccination with Spikevax.
