Hey! Tackling the UK vaccination schedule is a rite of passage for every UK medical student. It’s super high-yield for the AKT and honestly, just one of those things you'll be asked about on every GP rotation.

I've put together a clear breakdown of the current NHS routine childhood immunization schedule for you below.

Now, let's talk about contraindications. This is where the AKT examiners love to catch you out!

General Contraindications

• Anaphylaxis to a previous dose of the vaccine or any of its components (e.g., neomycin, streptomycin, or polymyxin B in some vaccines).
• Acute illness: If a child has a high fever, the vaccine is usually postponed until they are better. A simple "sniffle" or cold is not a reason to delay.

Live Vaccines (MMR, Rotavirus, Nasal Flu, BCG)

These are the big ones to watch for. You should avoid live vaccines in:

• Immunosuppressed children: Those on high-dose steroids, chemotherapy, or with certain primary immunodeficiencies (like SCID).
• Pregnancy: While not usually relevant for the childhood schedule, it's a key rule for live vaccines in general.

Specific Vaccine Rules

• Rotavirus: Contraindicated if there's a history of intussusception or if the child has SCID.
• Nasal Flu: Avoid in children with severe asthma or those who are currently wheezing.

AKT Pro-Tip: The MenB Fever The MenB vaccine is notorious for causing high fevers. Parents are advised to give prophylactic paracetamol (3 doses) starting immediately after the 8-week and 16-week appointments. This is the only vaccine where we routinely recommend paracetamol before a fever starts!

Let me find a visual aid to help you remember the key components of the 6-in-1 vaccine, as that's the backbone of the early schedule.

This diagram is a great way to visualize the different types of vaccines. Understanding whether a vaccine is live attenuated (like MMR or Rotavirus) or killed/subunit (like the 6-in-1) is the key to mastering those contraindication questions on the AKT.

To wrap up, just remember the 6-in-1 components:

1. Diphtheria
2. Tetanus
3. aPertussis (Whooping cough)
4. IPV (Polio)
5. Hib (Haemophilus influenzae type b)
6. HepB (Hepatitis B)

If you're ever in doubt about a specific vaccine's status (live vs. inactivated), the UK Green Book is your best friend. But for the AKT, the schedule and the live vaccine contraindications are the most important things to lock in!
