Side Effects of COVID Vaccine

COVID vaccine will help protect you from receiving COVID-19. May you get some side effects, which are common signs that your body is building defenses. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects.

Over the past few weeks, we talked about the COVID vaccine and the general questions around it. One of the biggest questions we have not yet been able to answer is what are the side effects of the COVID vaccine? In the following blog, we will answer this question in depth.

What are the common side effects to watch out for?

Note: While vaccine side effects are a normal part of building defenses against the virus in your body, if symptoms persist or worsen, please visit a doctor. These symptoms are minor, not debilitating. The COVID vaccine side effects are:

  • Pain, redness, or swelling at the injection site.
  • Fever or headache.
  • Fatigue or muscle aches.
  • To get a cold.
  • Nausea or vomiting.
  • Swollen lymph nodes.

1- Pain, redness, or swelling at the injection site:

Like many other vaccines, tenderness at the injection site is expected for most people. It should feel similar to a bug bite or injury. This side effect usually starts one or two days after receiving the injection and will last for a few days after their appearance.

2- Fever or headache:

If you develop this side effect, it will last for a day or two. It should go away within a few days. To reduce this side effect, place a cool compress on your forehead. The temperature will help reduce your fever and reduce headache pain.

3- Fatigue or muscle aches:

Talk to your doctor about taking over-the-counter medications such as ibuprofen, aspirin, and others for pain from such side effects. The CDC recommends not taking these drugs in the preparation of the vaccine.

4- Getting cold:

Getting cold is a common side effect of many vaccines and the COVID vaccine is no different. If you experience a cold, the best treatment is to rest, and take a warm shower to manage your cold.

5- Nausea or vomiting:

Although it is a more serious side effect, it is not uncommon. The best remedy for nausea is salt and ginger. Also, get lots of rest, and do not dominate yourself.

6- Swollen lymph nodes:

The lymph nodes are glands located in the neck. When someone has a bacterial or viral infection, these glands swell as an immune response. Because of how the vaccine works, it can function physically. The best treatment for this symptom is rest and a warm compress is applied to the neck.

Call a doctor if worse side effects persistent

Although these COVID vaccine side effects should be minor and should only last for a few days, if they persist, see a doctor. Symptoms should not persist or increase with the passage of time. If they do, then it is a sign of an allergic reaction to the virus.

Helpful Advice by Doctors for COVID Vaccine

Talk to your doctor about taking over-the-counter medications such as ibuprofen, acetaminophen, aspirin, or antihistamines for any pain and discomfort you may experience after getting vaccinated. If you do not have any other medical reasons that prevent you from taking these medicines normally then you can take these medicines to give relief from the side effects of post-vaccination.

It is not recommended that you take these medicines before vaccination to try to prevent side effects.

To reduce the pain and discomfort where you got the shot:

  • Apply clean, cool, wet washcloth over the area.
  • Use or exercise your arm.

To reduce discomfort from fever:

  • Drink lots of fluids.
  • Wear light clothes.

If you get another shot of the COVID vaccine:

Side effects COVID vaccine after your second shot can be more intense than what you experienced after your first shot. These side effects are common signs that your body is building defenses and should go away within a few days.

When to call the doctor:

In most cases, discomfort from pain or fever is a common sign that your body is building defenses. Contact your doctor or healthcare provider:

  • If the redness or tenderness where you got the shot worsens after 24 hours.
  • If your side effects are serious or don’t seem to go away after a few days.


  • Side effects can affect your ability to do daily activities, but they should go away in a few days.
  • You must keep using all means available to protect yourself and others until you have fully vaccinated.
  • After complete vaccination of COVID-19, you can start doing some things that you stopped doing due to the epidemic. When you have been fully vaccinated, you know more about it.
  • We are still learning how vaccines will affect the spread of COVID-19. After you have been fully vaccinated against COVID-19, you should wear masks in public places, stay 6 feet away from others, avoid crowds and poorly ventilated places and wash your hands frequently.
