Parent's question isn't answered in the article - no figure is given for how many deaths under 30 there are as a baseline.
From the article:
“We estimate that since its introduction [in 2008], HPV vaccination has prevented nearly 200 young women from dying from cervical cancer in England.”
This is an estimate of 200 total of any age total across 18 years. The article doesn't say 3300 die each year, 3300 are diagnosed each year.
The BBC article had that more comparable information: https://www.bbc.com/news/articles/c621z28z138o
> Between 2020 and 2024, no cervical cancer deaths were recorded in women aged 20 to 24 - the first time that had happened over a five-year period.
> Without vaccination, around 23 deaths would have been expected.
