Omicron cases currently stand at 22 within the UK, which will inevitably increase. However, a World Health Organisation official highlighted that there is no evidence to suggest the efficacy of vaccines will be reduced. There are around 40 different mutations of the Omicron Covid strain, with some changes indicating an increased risk of quicker transmission. Giving evidence at the Government’s science and technology committee on Wednesday, December 1 was Professor Neil Ferguson.

Professor Neil Ferguson is a British epidemiologist and professor of mathematical biology at Imperial College London.

He said that it wouldn’t be till “the end of the month” when a clearer picture of Omicron can be obtained.

Professor Ferguson added: “Viruses will evolve to become more transmissible.

“Like the Alpha variant was compared with the original strain of COVID, [and] like the Delta variant was more infectious.”

The professor said: “What we have seen is Alpha has been more severe than the previous strain, a little, and Delta more severe again.”

He cautioned: “”So the trend we’ve seen is greater severity not less severity.”

However, such mutations have been “countered by better treatment by monoclonal antibodies, antivirals and all the other drugs”.

As such, “people have a better chance of surviving severe COVID today than they did at the start of the pandemic”.
