Vaccination across a lifetime, not just in childhood

Vaccination is widely thought of as something that happens to children.

In practice it continues throughout life, and most adults cannot say what they are due.

Why adult vaccination exists

• Protection from some vaccines declines over time.
• Some diseases matter more with age.
• Some vaccines are only recommended from a certain age.
• Some conditions and treatments raise risk.
• Some occupations and destinations raise exposure.

Find out what you have had

• Ask your general practitioner for your record.
• Ask parents about childhood records if available.
• Check old school or military records.
• Keep anything you find permanently.
• Photograph it and store the image safely.

If nothing can be found

• Missing records are extremely common.
• For some vaccines the approach is simply to vaccinate.
• For others a blood test can check immunity.
• A clinician will advise which applies.
• Uncertainty is not a reason to do nothing.

Situations that change the recommendations

• Pregnancy.
• Weakened immunity from disease or treatment.
• Long-term heart, lung, liver or kidney conditions.
• Absent or non-functioning spleen.
• Certain occupations, including healthcare.
• Tell your clinician about all of these.

Ask before starting immune-affecting treatment

• Some vaccines should be given before treatment begins.
• Some cannot be given during it.
• Ask well before the treatment start date.
• This window is frequently missed.
• Raise it yourself if nobody else does.

Older adults

• Several vaccines are recommended specifically from older ages.
• Recommendations vary between countries.
• Ask what applies where you live.
• Ask whether anything can be given at the same visit.
• Ask about timing relative to other appointments.

Pregnancy

• Some vaccines are specifically recommended in pregnancy.
• Some are avoided during pregnancy.
• Ask your midwife or obstetrician rather than assuming.
• Protection can also pass to the baby.
• Ask about timing within the pregnancy.

Travel

• Seek advice at least six to eight weeks before departure.
• Some vaccines need multiple doses over weeks.
• Requirements depend on destination, season and activities.
• Some countries require proof of specific vaccination for entry.
• Keep the certificate with your passport.

Routine travel advice also matters

• Ask about preventive medicines as well as vaccines.
• Ask about insect bite avoidance.
• Ask about food and water precautions.
• Ask what to do if you become unwell abroad.
• Vaccination is only part of travel health.

After the injection

• A sore arm and feeling tired are common.
• Mild fever occurs with some vaccines.
• These usually settle within a day or two.
• Ask what would be unusual and worth reporting.
• Ask how to report a suspected reaction.

If you have had a reaction before

• Describe exactly what happened and when.
• Distinguish a severe allergic reaction from feeling unwell.
• Most previous reactions do not prevent future vaccination.
• Specialist advice is available for genuine allergy.
• Do not simply avoid all vaccination on the basis of one episode.

Why some vaccines need more than one dose

• Some require a course to build protection.
• Some require boosters to maintain it.
• An incomplete course may give little protection.
• Ask how many doses and at what spacing.
• Book the whole course at once if possible.
• Ask what to do if you miss the timing window.

Keeping a record

• Write down each vaccine, the date and where it was given.
• Keep certificates for travel requirements.
• Store a photograph in your phone.
• Take it with you when changing doctor or country.
• Systems do not follow you; your record does.

Moving country

• Schedules differ, so some vaccines may be new to you.
• Some you have had may not appear in the local record.
• Bring documentation and have it translated if needed.
• Ask what the local schedule recommends for your age.
• Ask specifically about children joining local schools.

Seasonal timing

• Some vaccines are offered seasonally.
• Timing affects how well protection covers the season.
• Ask when the local campaign begins.
• Book early rather than waiting for a reminder.
• Seasons differ between hemispheres, which matters if you travel.

Cost and funding

• Some vaccines are publicly funded and some are not.
• Funding depends on age and risk group.
• Ask what applies to you before assuming a charge.
• Ask whether insurance covers travel vaccines.
• Ask whether the price quoted includes the consultation.

Where to get vaccinated

• General practice, pharmacies and travel clinics all provide vaccination.
• Availability and cost differ between them.
• Ask which are funded and which are paid.
• Ask that the record reaches your general practitioner.
• A vaccine not recorded is effectively lost.

Household and close contacts

• Some vaccination decisions consider who you live with.
• Protecting a vulnerable household member is a valid reason.
• Mention newborns, pregnancy or immune-suppressed people at home.
• Ask whether that changes what is recommended for you.
• Ask whether it changes timing.

Combining appointments

• Several vaccines can often be given at one visit.
• This reduces missed doses considerably.
• Ask what can be combined safely.
• Ask whether anything must be separated in time.
• Ask for the whole plan in writing.

Evaluating what you read

• Use national health service and regulator sources.
• Ask your clinician about anything that worries you.
• Specific questions get better answers than general anxiety.
• Social media engagement is not evidence of accuracy.

The point to remember

Three things:

1. Keep your own permanent vaccination record — systems do not follow you.
2. Ask about vaccination before starting any treatment affecting immunity.
3. Seek travel advice six to eight weeks ahead, not the week before.
