The World Health Organization says it is tracking a few dozen cases of two new sub-variants of the highly transmissible Omicron strain of the coronavirus to assess whether they are more infectious or dangerous. It has added BA.4 and BA.5, sister variants of the original BA.1 Omicron variant, to its list for monitoring. It is already tracking BA.1 and BA.2 - now globally dominant - as well as BA.1.1 and BA.3. The WHO said on Monday (April 11) it had begun tracking them because of their "additional mutations that need to be further studied to understand their impact on immune escape potential". Viruses mutate all the time but only some mutations affect their ability to spread or evade prior immunity from vaccination or infection, or the severity of disease they cause. For instance, BA.2 now represents nearly 94% of all sequenced cases and is more transmissible than its siblings, but the evidence so far suggests it is no more likely to cause severe disease.

The National Health Service will begin its autumn Covid vaccine program next week, a month earlier than planned in response to the spread of a new variant dubbed Pirola. Covid vaccines will be administered to care home residents and housebound individuals from Monday onwards, while over-65s and other vulnerable groups will receive their appointments the week after. On Aug. 30, NHS England shifted the autumn vaccination drive to start on September 11 in response to the new Covid-19 variant, BA.2.86, detected on August 18. The primary groups can book through a national system upon receiving an invitation from the NHS. Some people may get an earlier call from their GP, and a few have already scheduled Covid vaccinations alongside their flu jabs. The NHS will begin inviting other eligible groups from Sept. 18. However, it is important to note that not everyone will receive a call at the same time. These groups will include individuals aged 65 and over, those aged six months to 64 years in a clinical risk category, frontline health and social care workers, and individuals aged 12 to 64 who are carers or household contacts of those with immunosuppression.

French drugmaker Sanofi said on Monday (June 13) an upgraded version of the Covid-19 vaccine candidate it is developing with GSK showed potential in two trials to protect against the virus's main variants of concern, including the Omicron BA.1 and BA.2 strains, when used as a booster shot. While the two companies' first experimental Covid shot is undergoing review by the European Medicines Agency, Sanofi and GSK have continued work on a vaccine that is moulded on the now-supplanted Beta variant, hoping still that it will confer broad protection against future viral mutations. Sanofi said this new vaccine candidate was shown to significantly boost antibody levels against a number of variants of concern, when given to trial participants who had an initial course of mRNA vaccines, a type made by BioNTech-Pfizer and Moderna. In a separate trial conducted by a French hospitals network, Sanofi's Beta-adapted booster shot triggered a higher immune response than Sanofi's first-generation shot or Pfizer-BioNTech's established vaccine in previously vaccinated volunteers.

Deviating from the initial schedule to kick off the flu and Covid-19 vaccination campaigns in October, the NHS England has announced that the autumn vaccination drive will commence sooner than expected in England, starting on September 11. This decision was taken as a precaution in response to a new Covid-19 variant. The precautionary measure is being taken as the Department of Health and Social Care and the UK Health Security Agency examined the variant BA.2.86, which was first detected in the UK on Friday, August 18, 2023, the NHSE said on Aug. 30. While NHS England had previously announced that vaccinations for both NHS programmes would begin on October 2 for residents of older adult care homes, appointments for other eligible groups were scheduled for the following week, starting on October 7. This decision prompted community pharmacy leaders to denounce the delayed start of the flu service as 'unacceptable'.

The NHS Confederation has urged the government to reconsider its 'living with Covid' plan and introduce mitigating actions that will help avoid further critical incidents being declared at the NHS front-line. The organisation said the high rates of Covid is having a major impact on the delivery of health services and slowing down efforts to reduce large waiting lists, noting that the country has been in the grip of another spike in Covid cases resulting from the Omicron BA.2 variant. With more than 20,000 patients now in hospital with Covid (or who have Covid but are in hospital for other reasons) and high staff absences, NHS is facing huge operational challenges, harming efforts to reduce waiting times in other areas, it said.
