It is reasonable for parents to ask questions. Good vaccine decisions should be based on reliable medical guidance, not fear, pressure, forwarded messages, or social media claims.

Myth: vaccines overload the immune system

Vaccines do not work by overloading the immune system. Children encounter many germs in daily life. Vaccines are designed to train immune memory against specific serious infections in a controlled way.

Myth: natural infection is always better

Natural infection can sometimes produce immunity, but it can also cause severe disease, hospitalisation, disability, or death. Vaccination aims to provide protection while reducing the risks of the disease itself.

Myth: multiple vaccines are unsafe

Receiving more than one vaccine at a visit may be recommended in routine or catch-up care. This should be done according to current official guidance and the child's health history, not by home calculation.

Mild illness and vaccination

A mild illness is not always a reason to delay vaccination, but the vaccinating doctor should assess the child. If there is fever, significant illness, breathing difficulty, or parental concern, discuss timing with the clinician.

How to check vaccine information safely

  • Use official medical, public-health, or paediatric sources.
  • Be cautious with posts that use fear, urgency, secrecy, or dramatic claims without references.
  • Ask your paediatrician if a claim worries you before delaying a vaccine.
  • Do not use social media posts to create a personalised vaccine schedule.

Why misinformation can be harmful

Social media posts may leave out context, exaggerate rare events, or confuse timing with causation. Delaying vaccines because of misinformation can leave children exposed to preventable infections.
