People hit with Covid over the Christmas period are being warned they are still at risk from the deadly virus.
Despite the holidays feeling just behind us, the immunity getting the virus offered is growing weaker leaving the populatiob more vulnerable to the latest coronavirus variants.
The BA.2 strain is a 'sister' of the Omicron BA.1 variant that swept rapidly across the UK in December and January, reports the Scottish Sun.
Thankfully symptoms associated with the new variants appear mild for the majority of the population with it's impact dampened by the widespread uptake of vaccinations.
Just shy of 39 million Brits are thought to have had both initial jabs and their booster.
Dr Nikki Kanani, deputy lead for the NHS covid-19 vaccination programme, urged people get their jab as “infections continue to rise”.
BA.2 is the fastest spreading variant to date and is behind the second Omicron wave which peaked last month.
Around 360,000 people have tested positive to Covid in the past week which is down 32% compared to the week before that.

While it is possible to catch both Omicron strains, current data suggests this is rare.
A UK Health and Security Agency (UKHSA) report in March found that only 43 double-Omicron infections had been identified out of 500,000 cases.
It is unclear if these infected people had been reinfected, or if they carried both strains at the same time.

The World Health Organisation said in February: “Reinfection with BA.2 following infection with BA.1 has been documented.
“However, initial data from population-level reinfection studies suggest that infection with BA.1 provides strong protection against reinfection with BA.2, at least for the limited period for which data are available.”
