What is a bivalent vaccine for Omicron strains?
The bivalent vaccine for Omicron strains is a "bivalent" vaccine that is compatible with both conventional strains and Omicron strains (BA.1 or BA.4-5).
On November 28th (Monday), the related ministerial ordinance was revised, and it became possible to inoculate the bivalent vaccine corresponding to the Omicron strain (BA.4-5) of the Moderna vaccine.
From December 10 (Saturday), the city will switch to the BA.4-5 compatible vaccine and inoculate.

Efficacy of bivalent vaccine for Omicron strain
It is expected to be more effective against the Omicron strain than conventional vaccines.
The booster vaccine for the Omicron strain contains the components of the Omicron strain, so when compared to the conventional vaccine, the immunity that contributes to the prevention of exacerbation, infection, and onset against the Omicron strain is stronger. Induce.
Therefore, against the Omicron strain, it is expected to have a greater effect in preventing severe disease than conventional vaccines, as well as an effect in preventing infection and disease, although the duration may be short .
Being a bivalent vaccine, it reacts to various novel coronaviruses.
Due to the presence of two different types of antigens, the induced immunity is also thought to respond to a wider variety of new coronaviruses.
Therefore, it is expected that it is more likely to be effective against future mutant strains .
*Based on expert discussions based on scientific knowledge as of August 2022. In the future, it may be updated due to the accumulation of knowledge.
