By six months the 6, 10 and 14 week series should be complete, and any missed dose can still be caught up without starting over. Teething, mild colds and hot weather are not reasons to delay, whatever the neighbourhood says. This guide covers the schedule, normal reactions, and the myths that keep Pakistani babies unprotected.
Pick the worry that fits your baby and open it for a clear answer, with what is usually normal, when to see a doctor, and when to go straight to hospital.
The routine primary infant series includes visits at 6, 10 and 14 weeks. The card commonly records pentavalent, polio, pneumococcal and rotavirus doses, with IPV at the scheduled visit. Current national and provincial guidance and the child's card are the final reference.
Pakistan's routine primary infant vaccine series includes a 14-week visit, with catch-up when doses are late. Mild short-lived pain, swelling, fussiness or fever may occur; campaign polio drops add protection but do not replace routine EPI doses.
A dose is late, the card is lost, the baby has a medical condition affecting vaccination, a reaction is worsening, fever persists, there is prolonged inconsolable crying or the family is considering delay because of a myth or minor illness.
After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Check every date and antigen, complete any missed 14-week doses promptly and mark the next visit. Bring the card to campaigns and clinic visits.
⭐ Zango Clinic’s view: At 4–6 months, this is the time to verify the full early series, not assume three injections or drops were all the same.
Teething, a mild cold or mild diarrhoea without dehydration often does not require delay. Moderate or severe illness needs individual assessment, but unnecessary postponement leaves the baby unprotected.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Tell the vaccinator all symptoms and medicines and allow assessment. Do not cancel on a relative's advice alone.
⭐ Zango Clinic’s view: At 4–6 months, teething and minor illness are common false reasons for delay; the vaccinator should decide.
Weather does not make a correctly stored vaccine unsafe. Low weight or weakness may make protection more important, although a severely ill baby needs assessment. Vaccine cold-chain quality is the programme's responsibility.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Attend a recognised EPI or vaccination centre, bring the card and discuss the baby's medical condition. Do not delay until winter.
⭐ Zango Clinic’s view: At 4–6 months, summer heat is not a reason to miss vaccines; using a proper cold-chain centre is the practical safeguard.
Brief soreness, mild swelling, fussiness or fever can occur and usually settles. Serious reactions are rare. Worsening swelling, persistent high fever, unusual sleepiness or prolonged inconsolable crying needs review.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Feed normally, use a cool clean cloth and ask for the correct weight-based medicine plan if needed. Do not massage oil or paste into the injection site.
⭐ Zango Clinic’s view: At 4–6 months, mild short reactions are expected; home applications add infection risk and severe symptoms must not be dismissed.
No. Campaign polio drops add protection and help stop community spread, but they do not replace the routine EPI doses and injections recorded on the child's card.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Accept eligible campaign drops and still attend all routine visits. Show the card and ask about catch-up if any dose was missed.
⭐ Zango Clinic’s view: At 4–6 months, campaign and routine polio vaccination work together; choosing one leaves gaps.
No credible evidence supports these claims. Vaccines train the immune system against specific dangerous infections. WHO safety systems monitor reactions, and serious vaccine harm is far rarer than severe disease.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Ask which disease each vaccine prevents and use WHO or official EPI information. Discuss one specific fear respectfully instead of forwarding unverified messages.
⭐ Zango Clinic’s view: At 4–6 months, local vaccine myths deserve calm facts; delaying protection because of infertility or autism rumours creates real risk.
Vaccines used in the national programme must meet quality and cold-chain standards. Private schedules may include additional products, but higher price does not automatically mean better protection from the same disease.

After vaccination there is breathing difficulty, facial swelling, collapse, seizure, extreme sleepiness, a purple rash, very high or persistent fever, or the baby looks severely unwell.
✅ What you can do: Use a recognised centre, keep a clear card and ask the clinician to explain any additional private vaccine and its timing.
⭐ Zango Clinic’s view: At 4–6 months, reliable storage, correct administration and complete schedule matter more than whether the dose was free or expensive.
Usually not. Most series continue with catch-up, but age limits matter for some vaccines, especially rotavirus. The exact dates should be reviewed promptly.

✅ What you can do: Take the card to an EPI centre or paediatrician now. Do not wait for the next campaign or start again without a written plan.
⭐ Zango Clinic’s view: At 4–6 months, prompt catch-up can preserve protection, but rotavirus age limits make delay especially important to address.
