Malaria Vaccine Side Effects 7 Lowdown on Heads Up

You’re packing for a tropical sun, sand, and adventure vacation. Has anyone checked into the necessary vaccinations? Malaria is common in foreign destinations so that a vaccine may be wise. As with any drug, there may be adverse effects. Read on to understand about malaria vaccine side effects before getting the dose. Get the inside scoop to balance the risks and advantages with this breakdown. Learn so you can make the best health decisions and enjoy the best vacation ever.

Understanding the New Malaria Vaccine

The first vaccine to combat malaria, which kills roughly half a million people annually, predominantly African children, is RTS, S. RTS, S was developed over 30 years by GlaxoSmithKline and the PATH Malaria Vaccine Initiative to defend against Plasmodium falciparum, the worst malaria parasite.

It Works How?

When infected mosquitoes bite, RTS and S activate the immune system to fight malaria. Malaria parasite proteins trigger antibodies and specific immune cells to kill the parasite when it enters the bloodstream or infects liver cells. According to studies, RTS, S prevents 4 in 10 malaria cases, including life-threatening severe malaria.

What are the Malaria Vaccine Side Effects?

Although RTS and S’s are usually minimal, all vaccines have adverse effects. The most common malaria vaccine side effects are injection site pain, redness, edema, fever, lethargy, joint pain, and headache. Convulsions, allergic reactions, and Guillain-Barré syndrome are rare but dangerous adverse effects. Similar side effects occur with other pediatric vaccinations.

When is it available?

The WHO suggested piloting RTS, S in Ghana, Kenya, and Malawi in 2023. RTS, S gives promise for millions at risk, especially children and families in malaria-endemic regions, even if widespread vaccine distribution across Africa may take years. This revolutionary vaccination promises a brighter future.

Most Common Malaria Vaccine Side Effects

Most adverse effects of the malaria vaccine are mild to moderate. Fortunately, life-threatening adverse effects are rare. Knowing the negative effects is vital to prepare and monitor yourself following immunization.

Injection site reactions

The injection site may swell, itch, and redden. Only a few days are typical. A cool compress can ease the pain. Contact your doctor if the swelling exceeds 10cm or doesn’t improve within a week.


The malaria vaccine may cause a fever, especially after the first dosage. It’s normal to reach 101°F. The fever should persist for a day or two. Take an OTC painkiller like acetaminophen or ibuprofen to decrease your temperature and relieve discomfort. If your fever exceeds 103°F, see a doctor.


Another typical malaria vaccine side effects is fatigue. The malaria vaccination causes an immunological response that temporarily drains energy. Rest, restrict intense activity, and hydrate. One week generally cures weariness. Consult a doctor if it persists or worsens.

Muscle pain

Back, arm, and leg muscle discomfort may be modest to moderate. Your immune system reacts to the immunization. Take an OTC painkiller and apply warm compresses to the sores. It should hurt less in a few days. Severe or persistent discomfort requires medical attention.

Fearful side effects are your body’s defense. Communication with your doctor and following doses will help you avoid a hazardous sickness. The pros outweigh the cons of vaccination, so roll up your sleeves and get protected!

Rare but Serious Side Effects to Watch Out For

Malaria vaccine side effects are usually minimal, but some might be significant. Monitor yourself or your child for worrying symptoms following the shot.

Allergic Reaction Severe

Anaphylaxis, a severe vaccination allergy, is rare. This might induce throat swelling, wheezing, fast pulse, disorientation, and weakness. After the shot, anaphylaxis usually occurs within minutes. Call 911 or go to the ER if these symptoms develop.

Guillain-Barré Syndrome

An uncommon condition, Guillain-Barré syndrome (GBS), causes muscle weakness and paralysis due to the immune system attacking nerve cells. The malaria vaccination causes GBS in 1 in 100,000 people. Within 6 to 8 weeks of immunization, legs, arms, chest, and face may feel weak or tingly. Please seek medical attention immediately if you encounter these symptoms.


Malaria Vaccine in India seldom causes meningitis and inflammation of the brain and spinal cord membranes. An intense headache, high temperature, stiff neck, confusion, seizures, tiredness, nausea/vomiting, and light sensitivity may occur. See a doctor immediately if you or your kid develops meningitis within 6–8 weeks of immunization. It can be fatal.

Although the risk of significant side effects is low, you should watch for any odd symptoms in yourself or your kid after obtaining the malaria vaccine. Report severe or unusual reactions to your doctor immediately. They can assess, treat, and report the reaction to vaccine safety monitoring systems.

Tips to Manage Malaria Vaccine Side Effects

Stay Hydrated

Drinking water or Gatorade can relieve fever, chills, and headaches. Hydrate with 6-8 glasses of water daily. It will also cleanse vaccination components from your system.

Get More Rest

Post-vaccination fatigue is usual. Your body strains to build immunity. Take it easy for a few days after the immunization. Sleeping more may reduce adverse effects and speed recovery.

Use Over-the-Counter Medications

Take acetaminophen, ibuprofen, aspirin, or naproxen for fever and pain. Benadryl helps with rashes, itching, and joint pain. Discuss your age and size with your doctor to determine the correct dosage. These drugs will relieve pain without compromising the vaccination.

Apply cool compress

Cover the injection location with a cool, moist towel for pain. Do this for 10-15 minutes every day, several times. A cooling sensation reduces pain and swelling. Icing packs wrapped in towels can also be utilized.

Monitor for Severe Side Effects

If you suffer from high fever (above 104 F), wheezing, hives, rapid heartbeat, or dizziness, visit your doctor immediately. Most malaria vaccine side effects are moderate. These can signal an allergic reaction and demand rapid medical intervention. How to treat severe or persistent side effects is best advised by your doctor.

Although unpleasant, malaria vaccination side effects signal your body is protecting itself. Follow these tips to keep comfortable as your immunity builds. The side effects should improve after a few days, and you’ll avoid malaria.

Is malaria vaccination safe?

The current malaria vaccine, RTS, S, has undergone rigorous safety testing and is approved for pilot implementation by the WHO. RTS, S has side effects like any vaccine; however, most are mild to moderate. The most common adverse effects are injection site discomfort and redness, headache, fatigue, muscle pain, fever, and nausea. Serious adverse effects are rare.

What are the most common side effects?

Pain, redness, and swelling at the injection site were the most common clinical trial adverse effects. One in three had a transient headache, fever, weariness, or muscle pain. These symptoms indicate the body is protecting itself and should subside in a few days. A cool compress or over-the-counter painkiller can ease injection site pain.

When and how long do side effects occur?

The malaria vaccine frequently causes side effects within three days. These mild to severe conditions usually clear up in a week. The most typical side effects are pain, swelling, and redness at the injection site. These usually last 2–3 days and start within a day. Headache, fever, and exhaustion start within 12 hours and persist for 3–7 days. If symptoms linger for more than a week, visit a doctor for Malaria Vaccine Side Effects.
