Do not target dominant strains

The two so-called vaccines “bivalent” which may get the green light from the EMA on Thursday target the original strain of the coronavirus, which emerged in China in 2019, and Omicron’s earlier BA.1 subvariant. However, they do not target the contagious BA.4 and BA.5 lineages of the Omicron variant, which have emerged in recent months as the dominant strains in the world.

The EMA, however, recently stated that it is aiming for approval “in the fall” of a Pfizer/BioNTech anti-Covid vaccine targeting the two Omicron BA.4 and BA.5 subvariants.

US health authorities on Wednesday authorized the new version of the Covid-19 vaccines from Pfizer and Moderna specifically targeting the BA.4 and BA.5 lineages of the Omicron variant.

Omicron and its sub-variants have been dominant throughout 2022, quickly taking the place of previous Alpha and Delta variants. The BA.4 and BA.5 subvariants are notably responsible for a wave of new cases in Europe and the United States in recent months.

All Omicron variants tend to have a milder disease course as they settle less in the lungs and more in the upper nasal passages, causing symptoms such as fever, fatigue and loss of smell.
