The Benefits of DPT
Mara Kardas-Nelson  should also note that as result of DPT controversy and the UK Vaccine Damage Payment Act of 1979 there were 600 payments in the period 1978-81 (1978/9: 36, 1979/80: 317, 1980/1: 256) [2,3]. The rhetoric behind the legislation was that injuries were rare but this was not borne out by the record [2,3]. The act enabled the government to retrieve the reputation of the programme amid adverse publicity by acknowledging the principle of harm but no one knew how many awards there had actually been - and initially there were a lot. This would also not take account of any deaths.
According to Mogensen et al, the introduction of DPT to Guinea-Bissau in 1981 was associated with a 5 fold increase in the rate of death :
"Among 3–5-month-old children, having received DTP (±OPV) was associated with a mortality hazard ratio (HR) of 5.00 (95% CI 1.53–16.3) compared with not-yet-DTP-vaccinated children. Differences in background factors did not explain the effect. The negative effect was particularly strong for children who had received DTP-only and no OPV (HR = 10.0 (2.61–38.6)). All-cause infant mortality after 3 months of age increased after the introduction of these vaccines (HR = 2.12 (1.07–4.19))."
