In addition to pertussis (and measles) outbreaks in fully‐vaccinated children, the outbreaks in the last thirty‐odd years have been occurring increasingly in very young babies, born to mothers who were vaccinated when they were babies and as a result they lack transplacentally‐transmitted immunity (TTI). Before the vaccine era, TTI protected babies and young children for up to two years against any infectious diseases of childhood
Due to the 1975 UK television program reporting on brain damage linked to DPT vaccine, the vaccination compliance fell down to 30%, or even 10% in some areas, in the UK. This was followed by the longest inter‐epidemic period with the lowest incidence of whooping cough on record.
