Vaccine side effects are frequently common. Rarely, they may result in more severe adverse effects, but it is quite unlikely that immunization will seriously harm us. Besides, common vaccine side effects, such as pain at the injection site, are often minimal and resolve rapidly without treatment.

It’s important to know that vaccine side effects are common and, like any drug, are subject to ongoing safety monitoring. By choosing not to get vaccinated, you are at risk of unnecessarily contracting an infectious virus that can be very serious or even fatal, putting you, your family, and the community at risk.


Vaccination often causes very minimal vaccine side effects. Some of these are:

  • Discomfort, redness, or edema at the injection site
  • Chills
  • Mild fever
  • Headache and feeling exhausted
  • Muscle and joint pain

Additionally, fainting can occur following any medical procedure, including vaccines.

It is highly uncommon for vaccinations to have serious negative effects. If that happens, these are:

  • Breathing problems
  • Throat or face swelling
  • Fast heartbeat
  • Severe rash that spreads over the body.
  • Disorientation and fatigue

Contact your healthcare professional if your symptoms are serious or last for longer than 72 hours.


Your doctor may diagnose vaccine side effects after you’ve received your shots. This diagnosis may depend on your symptoms. So, if you have any side effects following your vaccinations, be sure to consult your doctor for proper evaluation.


It’s important to remember that the majority of side effects are really signs that your body is developing immunity or protection against diseases.

To minimize side effects, you may consider the following:

  • Apply an ice pack or a cool, moist cloth to reduce swelling, discomfort, and redness at the injection site.
  • Take liquids frequently for one to two days after vaccination.
  • Take an OTC pain reliever.

Contact your healthcare practitioner if your symptoms are severe or persist for longer than 72 hours. It is also crucial to seek medical advice if you (or someone in your care) feel sick because it may not be the immunization’s cause but rather an underlying illness.
