Vaccinations given around 15 months of age, like other vaccines in early childhood, can cause some expected side effects. Based on information regarding vaccines for infants and children aged 0 to 6 years, these effects are generally mild and temporary.
Common Side Effects
The most frequently reported side effects associated with vaccinations in this age group include reactions at the injection site and general body responses. These common side effects are listed below:
- Injection Site Reactions:
- Pain
- Redness
- Swelling
- General Symptoms:
- Fever
- Drowsiness
- Loss of appetite
It's worth noting that local reactions, such as pain, redness, and swelling at the injection site, may become more common after later doses of some vaccines. For example, this is often observed after the fourth and fifth doses in a vaccine series.
Rare Side Effects
While most side effects are minor, very rarely, more severe reactions can occur. These are extremely uncommon but include:
- Severe allergic reactions (anaphylaxis)
- Brain swelling
It is important for parents and caregivers to be aware of these potential side effects and to contact a healthcare provider if they have concerns after vaccination.
Below is a summary table of the potential side effects:
| Type of Side Effect | Examples | Frequency |
|---|---|---|
| Common | Pain at injection site | More frequent |
| Common | Redness at injection site | More frequent |
| Common | Swelling at injection site | More frequent |
| Common | Fever | More frequent |
| Common | Drowsiness | More frequent |
| Common | Loss of appetite | More frequent |
| Rare | Severe allergic reactions | Very rare |
| Rare | Brain swelling | Very rare |
This information provides an overview of the potential side effects based on the general profile of vaccines administered to children in this age group, including those typically given around 15 months.
