Pfizer says its booster dose effective against Omicron COVID variant

Mikael Dolsten, Chief Scientific Officer of Pfizer
 
Drug manufacturers Pfizer and BioNTech say a booster shot of their coronavirus vaccine will be an effective defence against the Omicron variant of the coronavirus.
 
The companies said after a small study, three doses provide a similar level of antibodies against Omicron to that of two doses with other variants of the virus. 
 
"Our data show convincingly, when you get your boost - the third boost - the antibody level rise 25-fold and are now similar to the original two-dose dose that protected well against ancestral strains as well as Delta," revealed Mikael Dolsten, Chief Scientific Officer of Pfizer.
 
The World Health Organization earlier said vaccines should still work against severe Omicron cases.
 
Researchers across the world are piecing together data about Omicron.
 
It is the most heavily mutated version of the coronavirus found so far.
