The World Health Organization has approved a new malaria vaccine, giving it a second approval and helping to protect millions more people from the deadly disease.
The World Health Organization (WHO) has prequalified a second vaccine for the prevention of malaria. The RTS,S vaccine, developed by British drugmaker GlaxoSmithKline (GSK), was first given the green light in 2015. It was designed for children aged six weeks to 17 months and is given as four separate doses.
A clinical trial involving nearly 16,000 infants and young children in seven African countries showed that the vaccine was about 40% effective in preventing clinical episodes of malaria over the course of a year. The protection was greatest in those who received all four doses – rising to about 56%.
The WHO says that although the vaccine is not a “silver bullet”, it will make a “significant contribution” to reducing the burden of disease. Malaria is a major public health problem in Africa, where around 90% of all deaths from the disease occur. An estimated 429,000 people – mostly children under five – died from malaria in 2015.
This new vaccine gives hope that we may be able to achieve the WHO goal of reducing malaria cases by 90% by 2030. But there is still a long way to go – more effective vaccines are needed, and existing ones need to be used more widely.
WHO Approves Malaria Vaccine
The World Health Organization (WHO) has approved a new malaria vaccine, which is a major breakthrough in the fight against this disease. The vaccine, called RTS,S, is the first of its kind and is expected to save thousands of lives.
Malaria is a major problem in many parts of the world, particularly in Africa. Every year, there are millions of cases of malaria and hundreds of thousands of deaths. The majority of these deaths are in children under the age of five.
The RTS,S vaccine works by protecting against the most deadly form of malaria, Plasmodium falciparum. The vaccine is given as a four-dose course, with the first dose given at six weeks of age, and the last dose given at twelve months of age.
The WHO has recommended that the vaccine be used in combination with other measures to prevent malaria, such as bed nets and insecticide-treated mosquito nets. The vaccine is most effective when used in areas where the disease is common.

Benefits of the New Vaccine
There are a lot of benefits that come with the new malaria vaccine. For one, it is much more effective in preventing the disease. It is also much safer, with far fewer side effects. In addition, it is much cheaper to produce and distribute, which makes it more accessible to people in developing countries who are most at risk of malaria.
Malaria is a serious disease that causes a lot of suffering and death each year. According to the World Health Organization, it killed over 400,000 people in 2015 alone. The vast majority of these deaths were in Africa, where the disease is most prevalent.
The new vaccine is a major breakthrough in the fight against malaria. It is estimated to be up to 77% effective in preventing the disease, which is a huge improvement over the existing vaccines which are only about 30-50% effective. In addition, it is much safer than the existing vaccines, with far fewer side effects. It is also much cheaper to produce and distribute, which makes it more accessible to people in developing countries who are most at risk of malaria.
This new vaccine has the potential to save a lot of lives and reduce the burden of disease in Africa and other parts of the world where malaria is endemic. It is a major breakthrough in the fight against this deadly disease.
How the Vaccine Works
How the Vaccine Works? Malaria is a serious, life-threatening disease caused by a parasite that is transmitted to people through the bites of infected mosquitoes. The parasite then enters the bloodstream and travels to the liver, where it matures and multiplies. From the liver, the parasite enters the bloodstream again and infects red blood cells.
The symptoms of malaria include fever, chills, and flu-like illness. If not treated promptly, malaria can lead to severe illness, coma, and death.
There is no one definitive answer to the question of how the malaria vaccine works. However, there are a few leading theories.
One theory posits that the vaccine works by stimulating the body’s immune system to produce antibodies that recognize and kill the parasite.
Another theory suggests that the vaccine works by protecting red blood cells from being infected by the parasite.
The most likely explanation is that the vaccine works by some combination of these mechanisms.
The vaccine is given as an injection under the skin or into the muscle. It is usually given in two doses, with the second dose given four to eight weeks after the first.
The vaccine is safe and effective, but it is not yet available in all countries. In countries where the vaccine is available, it is recommended for people who are at high risk of malaria, such as travelers to areas where malaria is common.
Rolling Out the Vaccine
The world has made great progress in the fight against malaria. In the last 15 years, there has been a 60% reduction in malaria cases globally. This is thanks in part to the introduction of new malaria vaccines.
Now, there is a new push to Roll Out the Vaccine against malaria. The goal is to reduce the number of cases even further, and eventually eliminate the disease altogether.
There are many reasons why this is important. Malaria is a major cause of death, particularly in young children. It also puts a huge burden on healthcare systems, and the economy.
The new vaccine is based on a different approach than previous ones. It uses a weakened form of the malaria parasite, which is then injected into the person. This triggers an immune response, without causing the person to actually get sick.
The vaccine is still in the early stages of development, but it has shown promise in clinical trials. It is now being rolled out in several countries in Africa, where malaria is most prevalent.
The goal is to eventually have the vaccine available to all people at risk of malaria. This includes not just those living in Africa, but also travellers to malaria-endemic countries.
The new vaccine is an important tool in the fight against malaria. With its help, we can finally achieve our goal of a world without this disease.
Who is at Risk of Malaria?
Malaria is a potentially life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes. The parasites enter the blood stream and travel to the liver, where they mature and reproduce. From the liver, the parasites enter the blood stream and infect red blood cells.
Symptoms of malaria include fever, chills, headache, nausea, and vomiting. In severe cases, malaria can cause seizures, coma, and death.
Malaria is found in tropical and subtropical regions around the world, including parts of Africa, Asia, Central and South America, and the Middle East. According to the World Health Organization (WHO), malaria is a leading cause of death in Africa, where the majority of cases occur.
Who is at risk of malaria?
Anyone who lives in or travels to an area where malaria is found is at risk of the disease. However, certain groups of people are at higher risk of severe malaria, including:
- Children under 5 years of age
- Pregnant women
- People with weakened immune systems, such as those living with HIV/AIDS or certain types of cancer
- People who have sickle cell disease
How can you prevent malaria?
There is no vaccine available for malaria, but there are steps you can take to reduce your risk of contracting the disease. If you are living in or traveling to an area where malaria is found:
- Use mosquito nets and insect repellent
- Stay in air-conditioned or well-screened rooms
- Limit outdoor activity during dusk and dawn, when mosquitoes are most active
- Take anti-malarial medication as prescribed
Malaria’s Impact On Global Health
Malaria is a disease caused by a parasite that is transmitted to humans through the bites of infected mosquitoes. The disease results in high fevers, vomiting, and diarrhea, and can often lead to death. According to the World Health Organization, malaria is responsible for the deaths of over 400,000 people each year, most of whom are children under the age of five in Africa.
Malaria is a major public health problem in many parts of the world, especially in developing countries. The disease puts a huge burden on healthcare systems and economies, and limits the ability of people to lead productive lives. In Africa, for example, malaria is estimated to cost the continent over $12 billion each year in lost productivity and healthcare costs.
There is no silver bullet for malaria, but there are a number of different ways to prevent and treat the disease. One of the most important is through the use of mosquito nets and insecticide-treated bedding, which can dramatically reduce the number of mosquito bites a person receives. Another is through the use of drugs to prevent and treat malaria, including new malaria vaccines that have recently been developed.
The first malaria vaccine, RTS,S/AS01, was approved by the European Medicines Agency in 2015. The vaccine is not yet available in Africa, but clinical trials are ongoing. A second vaccine, RTS,S/AS02A, was approved by the WHO in 2019 and is currently being rolled out in three African countries (Ghana, Kenya, and Malawi).
The introduction of new vaccines is a major step forward in the fight against malaria. However, it is important to remember that no single intervention will be enough to eradicate the disease. A comprehensive approach is needed that includes mosquito control, diagnosis and treatment of infected individuals, and education about how to prevent mosquito bites. With continued efforts, it is possible to reduce the burden of malaria on global health.
Current Malaria Treatment Options
There are currently four approved drugs for the treatment of malaria:
- Chloroquine Phosphate
- Hydroxychloroquine Sulfate
- Mefloquine Hydrochloride
- Atovaquone Proguanil Hydrochloride
These four drugs are effective against the three major types of malaria parasites:
- Plasmodium falciparum
- Plasmodium vivax
- Plasmodium ovale
They are all available in oral forms, and chloroquine phosphate is also available as an injection.
The drugs work by preventing the parasites from growing and multiplying in the blood. They also kill the parasites, but this is not the main way they work.
The main side effects of these drugs are nausea, vomiting, and diarrhea. They can also cause headaches, dizziness, and skin rashes.
If you are taking any of these drugs, it is important to drink plenty of fluids to prevent dehydration.
These drugs are generally safe and well tolerated, but they can cause serious side effects in some people. If you experience any serious side effects, you should stop taking the drug and seek medical help immediately.
Malaria is a serious disease, and it is important to seek medical treatment as soon as possible if you think you may have contracted it. These four drugs are effective against the major types of malaria parasites, and they are safe and well tolerated. If you experience any serious side effects, you should seek medical help immediately.
Progress in Malaria Prevention
According to the World Health Organization, malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes. The parasites enter the victim’s bloodstream and travel to the liver, where they mature and reproduce. From the liver, the parasites enter the bloodstream and infect red blood cells, causing the victim to experience fever, chills, and flu-like symptoms.
Malaria is preventable and curable. In recent years, there have been great strides made in the prevention and treatment of malaria. Thanks to new malaria vaccines, improved diagnostic tools, and better access to treatment, the number of malaria cases and deaths has been reduced by 60% since 2000.
The RTS,S vaccine, also known as Mosquirix, was first approved in 2015. It is a preventive vaccine that helps protect people from Plasmodium falciparum, the most deadly form of malaria. The vaccine is given as a four-dose series, with the first dose given at six weeks of age, and the subsequent doses given at four-week intervals.
A second malaria vaccine, known as RTS,S/AS01E, has recently been approved by the European Medicines Agency. This vaccine is also used to protect against P. falciparum malaria, and is given as a three-dose series. The first dose is given at eight weeks of age, with the second and third doses given at four-week intervals.
Both of these vaccines are safe and effective at preventing malaria, and are an important addition to the existing arsenal of tools used to fight this deadly disease.

Conclusion: Malaria Vaccines
Malaria is a potentially life-threatening disease caused by Plasmodium parasites. These parasites are transmitted to people through the bites of infected female Anopheles mosquitoes.
Malaria is preventable and curable. However, malaria outbreaks still occur, particularly in sub-Saharan Africa, which bears the heaviest burden of the disease. In 2018, there were an estimated 228 million cases of malaria, resulting in the deaths of more than 400,000 people, most of whom were children under the age of 5 years.
There are several effective malaria control measures available, including vector control, chemoprevention, and case management. In addition, there are several promising malaria vaccines currently in development.
The first malaria vaccine, RTS,S/AS01 (brand name Mosquirix™), was approved by the European Medicines Agency (EMA) in 2015. In 2019, the second malaria vaccine, RTS,S/AS02A (brand name Mosquirix™), was approved by the EMA.
RTS,S/AS01 is indicated for use in children aged 6 weeks to 17 months living in sub-Saharan Africa who are at risk of exposure to malaria. RTS,S/AS02A is indicated for use in children and adults aged 5 years and older living in sub-Saharan Africa who are at risk of exposure to malaria.
The most common side effects associated with RTS,S/AS01 include fever, itching, swelling, and redness at the injection site. The most common side effects associated with RTS,S/AS02A include headache, muscle pain, and fatigue.
Malaria vaccines are an important tool in the fight against this potentially deadly disease. However, they are not a replacement for other existing control measures. It is important that people living in or travelling to areas where there is a risk of malaria continue to take steps to protect themselves from mosquito bites and promptly seek medical care if they develop symptoms of malaria.
