One of the important decisions for your baby’s health is getting his/her vaccination. Getting your baby vaccinated at 2 months is an essential thing in keeping them healthy. Many parents often ask, What are the 2-month immunization side effects? The idea of these side effects can be scary, especially if it’s the first time that your baby is getting vaccinated. We'll talk about the common and less common side effects and how to deal with them in this article.
Is Natural Immunity Better Than Vaccination?
Some parents have been asking themselves if it's safer to allow their infant to come down with the illness and build immunity or to be vaccinated. Vaccines, though, are safer.
When a baby becomes ill with diseases such as measles or whooping cough, the illness can be very dangerous. Some babies may be hospitalized or develop long-term complications. Vaccines will keep your baby safe without making them ill.
Vaccines work by introducing a weak version of illness to your baby’s immune system to teach them how to defend themselves against a stronger version. For this reason many are skeptical on its safety but many research prove that it's much safer than natural immunization. That’s why many doctors and even the World Health Organization (WHO) and the American Academy of Pediatrics (AAP) highly recommend them.
What to Expect After the 2-Month Immunization?
After the shots, your baby may feel a little off for a day or two. This is normal. Many babies get:
- A low fever
- Fussiness
- Sleepiness
- A small, sore bump where the shot was given
You may also notice an increase in crying and clinginess. These signs mean the body is building protection. But no need to panic as most side effects are temporary and will disappear in a couple of weeks.
Your baby may also sleep more than they normally would or be more cranky at night. Momcozy Smart Baby Monitor lets you closely monitor the post-vaccine behaviors of your baby, with HD video, real-time temperature monitoring, and night vision. It's a convenient device to ensure your baby is sleeping securely, and to watch for any signs that require a follow-up.
Common Side Effects After 2 Month of Immunization
Understand and learn about the possible side effects your baby might experience, can help you be calm and know what to do when it happens. So here are some of the common reactions babies experience after their 2-month immunization according to WHO.
Mild Fever
One of the common reactions your baby might get is fever that's under 38.5°C (101.3°F). This is normal and it means your baby’s body is trying to fight and build protection. At this time, you should keep your baby cool and make sure he or she drinks a lot of milk. If you get worried, you can ask your doctor for some paracetamol that is safe for your baby.
Redness or Swelling at the Shot Area
The place where the shot was given, most of the time on the thigh, might look red, warm to touch, or get a little puffy. This kind of reaction is normal and will go away after like two days. You can try putting cool clean cloth on it to help the swelling and so your baby feels more okay.
Sleepiness or Longer Naps
Many babies sleep more than normal after getting their shots. This happens because their body is working hard to make protection, and it uses a lot of energy. Just let your baby rest as much as they want, and try not to wake them up if not really needed.
Irritability or Crying
Your baby might get more fussy than usual or cry a lot. This is just how they show they don’t feel good, or maybe just tired. Some babies also want to carry more than normal. You can try holding, rocking, or feeding them to help them calm down.
Less Interest in Feeding
Some babies don’t eat much after getting their shots, but this only lasts for like a day. Just give milk more often and check if they look dry, like dry lips or not too much wet diapers. If your baby is still not feeding well after one day, it is better to call the doctor.
Side effects are normal; they are just there to remind you that your baby’s body is responding to the vaccine. Monitor it for a couple of days and it will disappear soon. You don't have to do anything, just let your baby’s immune system do its thing. Keep them comfortable and give them extra attention when they are having a hard time.
Uncommon or Rare Immunization Side Effects After 2 Months of Immunization
Most of the time, babies only experience the common side effects of shots. However, once in a while stronger might show up and may cause some scary complications. It’s important to know what to watch out for so you don’t panic when it happens.
- Febrile seizures: Although it may seem scary, this type of seizure doesn’t usually result in long-lasting problems. However, it's still important to seek medical attention if it happens.
- Allergic reaction: Allergy to medicines can happen, although its rare, always watch out for trouble breathing, swollen face or lips, and hives.
- High fever (over 39°C or 102.2°F): Your baby might look really tired or not act like their usual self. If this happens, you should call the doctor.
- Inconsolable crying: If your baby cries persistently for over 3 hours even after consolation, speak with your pediatrician. It may be a response to swelling or pain.
These reactions are rare, but it’s always best to be prepared. Trust your instincts, and if something feels wrong, call your baby’s doctor or go to the nearest clinic.

FAQs About 2-Month Immunization
Do Babies Sleep a Lot After 2 Months of Immunization?
After vaccination, more sleep than usual might happen to your baby because working hard is what their immune system does now. It’s part of how the body recovers, so a day or two of extra naps isn’t something to stress over. Letting them rest whenever they need and keeping things quiet around them helps. But if waking them becomes hard or feeding isn’t going well, a chat with the doctor might be the next thing to do.
How to Treat Baby Fever After 2 Months of Immunization?
Just pay more attention to your baby. Mild fever is temporary. Dress them in light clothes, keep the room cool, and offer more milk to prevent dehydration. You can also use a lukewarm sponge bath if they feel very warm. If your doctor has approved it, baby-safe paracetamol may be given to lower the fever. Avoid giving any medicine unless your pediatrician says it’s okay. Most fevers go away within 1–2 days.
How to Treat Baby Inconsolable Crying After 2 Months Immunization?
Inconsolable cries in babies are somewhat normal; however if it's after the vaccination, it may be caused by discomfort.

If this crying lasts longer than 3 hours or may be accompanied by high fever or changes in behavior, you should consult your doctor.
