Washington:
Merck’s anti-Covid tablet stays “energetic” in opposition to the Omicron variant, the US drugmaker stated Friday, citing outcomes from six laboratory research.

The most recent in vitro research, primarily based on cell-based assays, had been carried out independently by researchers in six nations: Belgium, Germany, the Czech Republic, Poland, the Netherlands and the USA.
