The UK pertussis epidemic: implications for immunisation

Area of Science:

• Public Health
• Epidemiology
• Immunology

Background:

• The UK is experiencing a pertussis (whooping cough) epidemic, characterized by high case numbers in adults and adolescents.
• There is a significant increase in severe pertussis cases and mortality among infants under 3 months.
• Despite consistently high vaccine uptake, the epidemic highlights challenges in pertussis control.

Purpose of the Study:

• To examine the background and contributing factors to the current pertussis epidemic in the UK.
• To review the history of pertussis and its control measures.
• To discuss the immunological principles influencing pertussis spread and control strategies.

Main Methods:

• Review of historical pertussis data and epidemiological trends.
• Analysis of current UK immunisation schedules and vaccine uptake.
• Examination of immunological factors related to pertussis transmission.

Main Results:

• Pertussis cases are disproportionately high in adults and adolescents.
• Infants under 3 months face a severe disease burden, with 14 deaths reported last year.
• The Joint Committee on Vaccination and Immunisation (JCVI) recommended antenatal pertussis vaccination.

Conclusions:

• The current pertussis epidemic necessitates a re-evaluation of control strategies.
• Maternal vaccination in the third trimester is recommended to protect vulnerable infants.
• Further consideration of additional control measures alongside the current immunisation schedule is warranted.
