The presenter shared the latest update on the pandemic after it was revealed the Pfizer vaccine could be 95 per cent effective.
Kate told viewers how the vaccine is able to fight the virus, saying: "Scientists take the part of the virus's genetic code with the distinctive spike protein. They then put this into a fat droplet that is injected into the patient.
"The code triggers the immune cells in the patient's body to make the spike protein. So, the immune system then reacts to the presence of the spike protein, by making antibodies which then go on to block the virus and the T cells which destroy infected cells.
"If the real virus appears in a body then these antibodies and T cells will fight it."
She added: "Complicated but also fascinating and it looks like a strong hope".
Pfizer was the first company to report its vaccine is effective, with it's latest data showing the jab is 95 per cent effective at preventing Covid-19.
On Monday, Moderna followed suit and become the second firm to announce their jab is 94.5 per cent effective. Their vaccine is yet to pass the final safety check stage.
Now the latest results from a new Oxford jab – thought to be among the front runners – has raised hopes that we could have three approved jabs within weeks.
Oxford Uni's Covid vaccine triggers an immune response in all ages – including the elderly, new results published today reveal.
In a major breakthrough it was found to "trigger a robust immune response" with no serious side effects in those aged 56-79 and the over 70s.
