Vaccinations are one of the most important ways to protect your child from serious diseases, yet, in today’s world of information overload, where it is easy to find information and have it at our fingertips, it can still be overwhelming. There is a wealth of information available, but with it comes a significant amount of misinformation, especially for parents who are concerned about their children and need immediate, reliable guidance.
That’s why Dr Anisa Vahed advocates for informed, evidence-based information and welcomes you to reach out when you are not sure about paediatric care. For example, when it comes to vaccinations, many people have been misinformed, something that became particularly clear during the COVID-19 pandemic. But when it comes to your little one’s health, it is so vital to understand why vaccinations remain one of the most important tools in paediatric care.
What are vaccines?
Vaccinations, or immunisations, help reduce your child’s risk of getting infected with certain diseases. They teach your immune system to recognise and respond to specific bacteria or viruses without causing illness. In simple terms, vaccines train your child’s body to fight off infections by helping build antibodies, which are special proteins that help destroy harmful pathogens (disease-causing microorganisms).
How do vaccines work?
When your healthcare provider gives your child a vaccination, usually by injection, it introduces a harmless component of the disease-causing germ (such as an inactivated virus or a tiny protein fragment). This doesn’t make your child sick, but it does stimulate the immune system to respond.
Think of it as a “practice run” for the immune system: it learns what the threat looks like and stores that memory. So, if your child is exposed to the real germ in the future, their immune system can react quickly and effectively, often before any symptoms even appear.
Why are childhood vaccinations so important?
Vaccines don’t just protect your child, they protect your entire community. This is called herd immunity. When enough people are vaccinated, it makes it harder for diseases to spread. This protects the most vulnerable members of society, such as newborns, the elderly, and those with weakened immune systems.
Many diseases that were once life-threatening, like measles, polio, and whooping cough, are now rare in South Africa and globally, thanks to widespread vaccination. But if vaccination rates drop, these diseases can return.
Common concerns and the facts
It’s completely natural to have questions or worries, especially with so much misinformation circulating online. Let’s clear up a few of the most common concerns:
“Can vaccines cause autism?”
No. This myth has been thoroughly debunked by decades of research. Vaccinations are safe, and there is no scientific evidence linking them to autism.
“Isn’t it too much for a baby’s immune system?”
Actually, babies’ immune systems are incredibly strong and capable of handling far more than what’s in the recommended vaccine schedule. Every day, babies encounter and fight off hundreds of germs; vaccines are just a safer, controlled way to help build protection.
“Do vaccines have serious side effects?”
Most side effects are mild, like a slight fever or soreness at the injection site. Serious reactions are extremely rare, and your paediatrician is trained to manage them.
What to expect after vaccination
After a vaccine, it’s normal for your child to feel a little unwell for a day or two. You might notice:
- Mild fever
- Irritability or fussiness
- Redness or swelling at the injection site
These are signs the immune system is responding. You can help by offering comfort, fluids, and rest. If symptoms persist or you’re concerned, always contact your doctor or paediatrician.
The South African Vaccination Schedule
South Africa’s Department of Health provides a comprehensive Expanded Programme on Immunisation (EPI), starting from birth. Key vaccinations include:
- BCG (for TB) and OPV (polio) at birth
- DTaP-IPV-Hib-HepB at 6, 10, and 14 weeks
- Measles at 6 months and 12 months
- Additional vaccines like rotavirus, pneumococcal, and HPV are also available, especially in the private sector
It’s a good idea to keep a vaccination card or use a tracker to stay on schedule.
Final thoughts
As a paediatrician, Dr Vahed sees every day how vital vaccinations are in giving children a healthy start in life. They are one of the safest and most effective ways to prevent disease or illness and keep your little ones thriving.
If you’re feeling unsure or overwhelmed, know that you’re not alone. Dr Vahed is here to listen, answer your questions, and help you make informed decisions.
Your child’s health and safety are always worth protecting.
