I do not think anyone could really claim that any age group in Torridge was close to endemicity.
Even now cumulative reported Covid prevalence in Torridge remains low in comparison to the rest of the country - under 10,000 per 100,000 population (vs 17,000+ in high hit ares). Unfortunately, this means Torridge and other local authorities with similar "low" historic attack rates (e.g. Suffolk, Devon, Cotswolds, etc) have got large pockets of susceptible population and are likely to see Covid spikes in the future.
