At Akasi Pharmacy, we speak to parents every day who want the best for their children—but often feel anxious when it comes to vaccinations. It’s completely normal to worry about side effects or reactions after a jab. We’re here to offer clarity, support and reassurance.

Vaccines are a crucial part of your child’s health journey. They protect against serious illnesses that were once widespread but are now largely preventable, thanks to the children’s vaccination schedule followed across the UK. While side effects do occur, they are usually mild, short-lived, and far outweighed by the benefits of protection.

Let’s explore the reality of vaccine side effects, how to care for your little one afterwards, and when it’s appropriate to seek medical help.

What Side Effects Are Normal?

Most side effects from children’s vaccinations are a sign that the immune system is responding as it should. Common side effects include:

Redness, swelling or tenderness at the injection site – This is especially common with vaccines like the 6-in-1 or MenB.

Mild fever – A slight temperature can occur after many childhood vaccines, particularly the MMR or flu vaccine.

Irritability or tiredness – Your child might be a little fussier than usual or sleep more.

Loss of appetite – A temporary dip in appetite can follow certain jabs.

These symptoms typically resolve within 24–48 hours and are no cause for concern. Some vaccines, like MenB, may cause a higher fever in babies under one year old, which is why paracetamol is often recommended post-vaccination.

Caring for Your Child After Their Jabs

Here are a few simple tips to help your child feel more comfortable after their vaccinations:

–> Give infant paracetamol as advised by your pharmacist or GP—especially after the MenB vaccine.

–> Offer extra fluids to keep your child hydrated, especially if they’re running a slight temperature.

–> Cuddle and comfort them—they may just need reassurance and rest.

–> Dress them in light clothing if they’re running warm, and avoid bundling them up.

If they’re old enough to understand, talking them through the process in calm and positive language before and after their appointment can help reduce anxiety around future visits.

When Should You Seek Medical Advice?

While serious reactions to vaccines are extremely rare, it’s always better to be cautious if something doesn’t feel right. Contact your GP or seek urgent care if your child experiences:

–> A high fever (over 39.5°C) that doesn’t respond to medication

–> Non-stop crying or inconsolable distress lasting more than 3 hours

–> Seizures or fits (febrile convulsions can occasionally happen with high fever)

–> Signs of allergic reaction such as swelling of the face, difficulty breathing, or a widespread rash (very rare)

At Akasi Pharmacy, we always encourage parents to speak with a healthcare professional if they’re unsure—there’s no such thing as a silly question when it comes to your child’s wellbeing.

Key Vaccines in the UK Children’s Vaccination Schedule

The UK’s vaccination programme is one of the most effective in the world, offering protection against a wide range of serious illnesses. Here are six of the most important childhood vaccines:

6-in-1 Vaccine – Protects against diphtheria, hepatitis B, Hib, polio, tetanus and whooping cough. Given in three doses at 8, 12, and 16 weeks.

Pneumococcal Vaccine (PCV) – Shields against pneumococcal infections like pneumonia and meningitis.

Rotavirus Vaccine – An oral vaccine that protects babies from severe diarrhoea caused by rotavirus.

MenB Vaccine – Guards against meningitis B, a rare but potentially deadly infection.

MMR Vaccine – Offers immunity against measles, mumps and rubella, usually given at 12 months and again before school.

Flu Vaccine – Given annually as a nasal spray to children from age 2 and up, including school-age groups.

Additionally, children aged 12–13 are offered the HPV vaccine, which protects against human papillomavirus and significantly reduces the risk of certain cancers later in life.

What About the Chickenpox Vaccine?

Chickenpox isn’t currently part of the NHS’s routine children’s vaccination schedule, but it’s available privately—and we offer it here at Akasi Pharmacy.

While often considered a mild illness, chickenpox can be more severe in some children and may lead to complications such as skin infections, pneumonia or even hospitalisation. The chickenpox vaccine is particularly beneficial for:

–> Children with underlying health conditions

–> Siblings of immunocompromised individuals

–> Families planning travel, especially to countries where exposure risk is higher

The vaccine is given in two doses, usually four to eight weeks apart, and provides excellent protection with minimal side effects.
