Catch up vaccination adults
Informed by recognized medical guidance
Overview
Catch-up vaccination for adults is a way to get vaccines you missed as a child or need updates for as an adult. Vaccines help protect you from serious diseases like measles, whooping cough, and tetanus. A catch-up schedule can fill in any gaps in your protection.
Key facts
- Catch-up vaccination is safe and effective at preventing disease.
- Many adults missed full vaccine schedules during childhood.
- You can get catch-up vaccines from your general practice (GP) or local health clinic.
Yes, it is common for adults to need catch-up vaccination. Many people missed vaccines as children or have lost immunity over time. Public health programmes often recommend catch-up doses.
Catch-up vaccination can benefit any adult who is not fully protected. It is especially recommended for people planning travel, starting a family, working in healthcare, or caring for young children.
Symptoms
- Severe allergic reaction (anaphylaxis) after a vaccine: difficulty breathing, swelling of the face or throat, hives all over the body, rapid heartbeat.
- Signs of a serious infection such as high fever with confusion or stiff neck.
- ⚠Fever that lasts more than a few days after vaccination.
- ⚠Severe headache, vomiting, or unusual weakness after a vaccine.
- ⚠Any new symptoms that concern you.
Common symptoms
- There are no symptoms from missing a vaccine, but the disease you are not protected against can cause symptoms such as fever, rash, cough, or muscle aches.
- After receiving a catch-up vaccine, you might have mild side effects like soreness at the injection site, low fever, or tiredness. These are normal and usually go away within a day or two.
Symptoms in children
- Not applicable for adults, but if you are catching up as a young adult, vaccines are the same as for adults.
Symptoms in older adults
- Older adults may have a higher risk of serious illness from vaccine-preventable diseases, so catch-up vaccination is particularly important. Side effects are generally the same as for other adults.
Causes
Main causes
- Not receiving all recommended vaccines during childhood or adolescence.
- Moving between countries with different routine vaccine schedules.
- Losing immunity over time (for example, for tetanus or whooping cough).
- Being born when a vaccine was not yet available (for example, the chickenpox vaccine).
Risk factors
- Under-vaccinated childhood due to parental decision, lack of access, or medical conditions.
- Living or working in settings with higher disease risk, such as healthcare, childcare, or travel to areas with circulating diseases.
- Chronic health conditions that make you more vulnerable to infections.
When to see a doctor
See a doctor urgently if:
- If you think you have been exposed to a serious vaccine-preventable disease like measles or meningococcal disease.
- If you develop severe symptoms after a vaccine (as noted in the emergency section).
Book a routine appointment if:
- To check which vaccines you might need – for example, when starting a new job, planning pregnancy, or travelling.
- If you are unsure about your vaccination history.
Diagnosis
There is no single test to diagnose missed vaccines. Instead, your healthcare provider will review your personal and family immunization records, ask about your history, and sometimes test your blood for antibodies to certain diseases.
Tests that may be done
- Review of immunization records (vaccination card, childhood documents).
- Blood tests to check antibody levels for diseases like measles or hepatitis B.
What to expect at your appointment
Your doctor will ask about your age, health conditions, travel plans, and previous vaccinations. They will then recommend a catch-up schedule, which may involve several vaccines given over weeks or months. You will be monitored for immediate side effects for about 15 minutes after each shot.
Treatment
Catch-up vaccination is the treatment itself. It means receiving one or more vaccine doses according to a schedule tailored to your age and health. The vaccines are given as injections, usually in the upper arm. Some vaccines require multiple doses for full protection.
Self-care at home
- Apply a cool, wet cloth to the injection site to reduce soreness.
- Move your arm normally to help the vaccine spread.
- Take paracetamol or ibuprofen if you have a mild fever or discomfort – always follow the package instructions or ask a pharmacist.
Medical treatments
Your doctor or nurse will give you the recommended vaccines. For certain diseases, you may also need a booster dose later. If you have a health condition that weakens your immune system, your doctor may adjust the schedule or give extra doses. Always discuss any concerns with your provider.
When is surgery considered?
Surgery is not relevant to catch-up vaccination.
Living with this condition
Once you are fully vaccinated, you can go about your daily life with reduced risk of several diseases. Keep a record of your vaccinations for future reference.
Lifestyle tips
- Stay up to date with other recommended health checks.
- If you travel, check with a travel clinic if you need additional vaccines.
- Inform your healthcare provider of any new health conditions.
Diet and exercise
No special diet or exercise is needed for vaccination. A healthy lifestyle supports your immune system overall.
Mental health and emotional wellbeing
Some people feel anxious about needles or side effects. This is normal. Talk to your doctor about ways to reduce discomfort, such as distraction techniques or numbing cream. The peace of mind from being protected can also reduce worry.
Prevention
Yes, catch-up vaccination prevents many diseases that you missed being vaccinated against. Staying on schedule with future vaccines also prevents further gaps.
Vaccines
Vaccines for adults include those for tetanus, diphtheria, whooping cough, measles, mumps, rubella, polio, hepatitis B, human papillomavirus (HPV), shingles, pneumococcal disease, and meningococcal disease. Your doctor will tell you which ones you need.
Screening programmes
No regular screening is needed for vaccine-preventable diseases, but blood tests can check for immunity if you are at risk.
Complications
If left untreated
- Increased risk of catching and spreading serious diseases like measles or whooping cough.
- Possible hospitalisation from complications of these diseases, especially for pregnant women, older adults, or those with weakened immune systems.
- Long-term effects such as infertility from mumps or liver damage from hepatitis B.
Long-term outlook
With catch-up vaccination, you can nearly eliminate your risk of these diseases. Even if you are starting later in life, each dose adds protection. It is a safe and effective way to take charge of your health.
