At this point in time, there are believed to be about 4,000 variants of COVID-19 circulating around the world.
Vaccines Ministers Nadhim Zahawi recently revealed the figure on TV, adding that vaccine manufacturers are aware of the situation.
Mr Zahawi said: “All manufacturers are looking at how they can improve their vaccine to make sure we are ready for any variant.
“There are about 4,000 variants around the world of Covid-19 right now.”
Although there are believed to be thousands of variants, they haven’t all been identified aside from a handful.
