Today, we’re speaking to Dr Karol Basta, a Public Health Registrar based in London.Title of paper: Predictors of Childhood Vaccination Uptake and Timeliness in a Diverse Urban PopulationAvailable at: https://doi.org/10.3399/BJGP.2025.0319Childhood vaccination rates have declined in the UK, with inequalities in urban, deprived, and ethnically diverse populations. Previous studies have lacked individual-level clinical data or did not explore both uptake and timeliness. We analysed 13 years of routinely collected primary care data for over 37,000 children in a diverse London borough to identify predictors of uptake and timeliness. Distinct sociodemographic and clinical factors were associated with incomplete and delayed vaccination, offering timely insights as responsibility for vaccination services shifts closer to local systems and place-based commissioning.TranscriptThis transcript was generated using AI and has not been reviewed for accuracy.

Thanks for taking the time to listen to this podcast today.In today's episode, we're speaking to Dr. Carol Basta.Carol is a public health registrar based in London and we're here to talk about the paper she's recently published here in the bjgp, which is titled Predictors of Childhood Vaccination Uptake and Timeliness in a Diverse Urban Population. So, hi, Carol, it's really lovely to meet you and to talk about this work. And I guess just to start, I wanted to put this work into context.We know that in the uk, overall childhood vaccination rates have unfortunately been declining. Could you talk us through some of the current challenges around vaccination, especially in urban and diverse areas?Speaker B00:00:52.720 - 00:02:06.750Yep. So we know vaccinations are really powerful and cost effective tools we have in giving children the best start in life life.But unfortunately, in the UK, since 2012, the uptake has been declining and actually since 2021, none of the vaccines in England have reached the 95% target recommended by the WHO to stop communicable disease outbreaks. And the kind of negative consequences of this aren't just sort of future hypothetical risks.We've already been seeing vaccine preventable diseases such as measles and whooping cough resurgences, and this is especially in certain parts of the uk, such as London or the northwest of England. So no uptake of vaccines is decreasing and vaccine preventable diseases are increasing. But that's not the full picture.We also know, for example, following work done by, at the time, Public health England in 2017, there are avoidable inequalities across the childhood vaccination program nationally, for example, linked to deprivation, geography and ethnicity.However, what was missing was really kind of contemporary granular evidence on the social and clinical factors associated with unequal vaccine outcomes, especially in diverse urban environments.Speaker A00:02:06.990 - 00:02:16.670And I know this was highlighted as well during COVID but there is a mistrust of health services amongst some communities as well, which might be playing into this.Speaker B00:02:17.470 - 00:03:11.120Yeah, exactly.So at the time when I was working in Lamb of Council, we knew qualitatively from talking to our community and talking to our local GP partners, that there was kind of sense of rising mistrust in healthcare services, but also rising difficulties with actually access to services.And that doesn't just affect whether or not people can get the vaccine, for example, it also affects whether they can have conversations about vaccines and the kind of continuity of care and building up those relationships.And so this is what we had kind of on a local level, but we knew that there was also national feelings and sentiments around mistrust, not just national, but actually globally vaccination mistrust from the COVID 19 pandemic. And there were worries that this had run off into the childhood vaccination program as well, that it hadn't just confined itself to Covid vaccines.Speaker A00:03:11.440 - 00:03:41.490So this was a study looking at predictors of routine childhood vaccination from 40 general practices in Lambeth and London, which is a pretty ethnically and socioeconomic demographically diverse borough. And you looked here at the vaccination uptake and timeliness and some of the predictors for these. This was a really big sample.But just to underline the population here, tell us more about the demographics in Lambeth as a borough in terms of ethnicity, because that's where you were based when this work was done.Speaker B00:03:41.890 - 00:04:32.250Yeah, exactly.So Lambeth is an inner London borough and it is very ethnically diverse, it's very densely populated, but it also has some of the highest levels of deprivation in the country. And part of ...
