As scientists speed towards a vaccine for coronavirus, there’s a fear drugs will not work against mutations of COVID-19. Luckily, a new study finds this wont be the case.

A new study has found that they will work against the new G-strain mutation of the coronavirus, according to journal ‘npj-Vaccine’, brought out by Nature.

Key Insights:

• Most vaccines being developed are based on the original COVID strain - “D-strain” which was also more common during the early months of the pandemic.

• Since then, the “G-strain” has actually overtaken it to become the more common type of coronavirus infecting patients. This mutation, known as D614G, now accounts for about 85 percent of the virus particles being found.

• Study tested blood samples from ferrets who received a possible coronavirus vaccine. There was no evidence a mutation in COVID-19 affects the impact of their drug.

• G-strain is unlikely to require frequent ‘vaccine matching’ where new vaccines need to be developed seasonally to combat the virus strains in circulation, as is the case with influenza.

• “This brings the world one step closer to a safe and effective vaccine to protect people and save lives,” CSIRO Chief Executive Dr. Larry Marshall says.

The study appears in the journal npj Vaccines.
