The whooping cough jab was first introduced on NHS 1957 (diphtheria 1942 and tetanus 1961 according to the government list - I'm still looking for the date that the DPT combo (aka DTwP) first rolled out in UK, but can only find the US dates, which are earlier - end of the 1940s)
The controversy (over brain damage, which the vaccine appeared to cause in the unlucky few - report by GOSH in 1974, 36 cases) led to widespread mistrust of the vaccine and a massive fall in uptake, even some doctors ceased recommending it. Despite safely studies (looking at all children in UK who had the same type of neurological condition, and failing to find a definitive link to the vaccine), the controversy reignited in the US in 1982. Some companies even stopped making the jab, which stoked public concerns. There were a huge number of lawsuits.
It only really went away when the pertussis element was reformulated into an acellular version (DTaP late 80s? early 90s?)
In the time of the controversy, there was still a DT jab, so children were protected against those two (they didn't give whole pertussis jab to adults, because of risks, which again stoked the controversy over whether children should have it), and also a single tetanus (in widespread use as it was given routinely after deep puncture wounds)
