Vaccination Programs and Schedules
UK Childhood Vaccination Schedule
| Age | Vaccines | Diseases Protected Against | Type |
|---|---|---|---|
| 8 weeks | 6-in-1, Pneumococcal, Rotavirus | Diphtheria, tetanus, pertussis, polio, Hib, hepatitis B, pneumonia, gastroenteritis | Multiple |
| 12 weeks | 6-in-1, Pneumococcal, Rotavirus | Second doses | Multiple |
| 16 weeks | 6-in-1, Pneumococcal, MenB | Third doses plus meningitis B | Multiple |
| 1 year | Hib/MenC, MMR, Pneumococcal, MenB | Boosters plus measles, mumps, rubella | Live attenuated |
| 3-4 years | 4-in-1, MMR | Pre-school boosters | Mixed |
| 12-13 years | HPV | Human papillomavirus (cervical cancer prevention) | Subunit |
| 14 years | 3-in-1, MenACWY | Tetanus, diphtheria, polio boosters, meningitis | Multiple |
Benefits of Vaccination Programs
- Individual protection: Direct immunity for vaccinated person
- Community protection: Herd immunity protects vulnerable populations
- Disease eradication: Global elimination possible (e.g., smallpox)
- Economic benefits: Reduced healthcare costs, increased productivity
- Travel safety: Protection when visiting endemic areas
Risks and Considerations
- Common side effects: Mild fever, soreness at injection site
- Rare serious reactions: Anaphylaxis (1 in 1 million doses)
- Contraindications: Immunocompromised individuals and live vaccines
- Religious/philosophical objections: Balanced against public health needs
- Vaccine hesitancy: Misinformation requiring scientific education
Practice questions for Vaccination and Herd Immunity
What do vaccines contain?
Explain how vaccination protects a person from getting a disease. [3 marks]
Quick recall flashcards
Why don't vaccines cause the disease they protect against?
Vaccines use dead or inactive pathogens, or just antigens from the pathogen's surface.
The pathogen cannot multiply or cause infection.
The immune system still recognises the antigens and builds immunity.
What is a vaccine and how does it work?
A vaccine contains a dead or weakened form of a pathogen (or its antigens).
It triggers the immune system to produce antibodies and memory cells without causing disease.
If the real pathogen enters later, memory cells respond rapidly.
