New research conducted by Pfizer together with the University of Texas suggests the COVID-19 vaccine manufactured by the company is effective against two highly contagious strains of the virus recently found in the UK and South Africa.

Both strains share the same mutation of their spike protein, which is used by the virus to make it into the cell. The mutation is believed to be the reason why the new variants demonstrated increased transmissibility.

The researchers used blood from 20 people who had received the Pfizer jab during the vaccine trials to see if the antibodies could eliminate the virus after exposure.

According to the study published Thursday on biorxiv, which is yet to go through a peer review, the result was a success.

“It was a very reassuring finding that at least this mutation, which was one of the ones people are most concerned about, does not seem to be a problem,”  Pfizer chief scientific officer Dr. Philip Dormitzer said.

Earlier, the concerns about the new mutation prompted a number of countries to suspend their air links with the United Kingdom.

The UK recently tightened its lockdown rules in a bid to ward off the soaring new infections.
