New Vaccination Campaign: Protecting Against Covid-19’s Eris and BA.2.86 Variants

2023-08-23 11:23:00

While the epidemic rebound of Covid-19 is confirmed, with the influence of the two new variants “Eris” and “BA.2.86”, the Ministry of Health will launch, from October 17, a new vaccination campaign in a city. This aims to “prevent the arrival of winter, a period conducive to the circulation of respiratory viruses”.

If this new vaccination campaign is coupled with that of the flu, it is mainly aimed at people at risk.

Thus, it concerns, in the first place:

– people over 65,

– patients with comorbidities (diabetes, obesity, chronic diseases, etc.),

– immunocompromised

– pregnant women.

Vaccination is also recommended for people in contact with them, as is the case for example for caregivers. Since the beginning of the summer, two new forms of Covid-19 have been detected. The first is indeed a sub-variant of Omicron, scientifically named EG.5, also nicknamed “Eris”.

With 32 mutations in the Spike protein, which plays an essential role in infection, “Eris” would be more contagious than Omicron.

First identified in the United States and the United Kingdom in July 2023, the “Eris” subvariant is responsible for the rise in cases in these two countries.

London had estimated that this new form of Omicron would be the cause of at least 15% of cases across the Channel, when Washington had recorded, in mid-August, 9,000 new hospital admissions, most of them patients were carriers of “Eris”.
