The World Health Organization in its weekly epidemiological update dropped shocking evidence which now triggered new tensions amidst raising cases. Preliminary evidence indicates that COVID-19 vaccines may be less effective against infection and transmission linked to the Omicron coronavirus variant, which also carries a higher risk of reinfection.
Findings suggest a drop in antibody counts when two shots are pitted against Omicron for mRNA vaccines, and also for adenovirus-based vaccines. However, preliminary evidence also shows that the third dose of mRNA vaccines can at least partially restore antibody levels.
On this note, most vaccine makers have said they have begun work on assessing new vaccines against Omicron. The Delta variant on the other hand, is still dominant accounting for 99.2% of the almost 880,000 sequences uploaded to GISAID with specimens collected in the last 60 days.
