Ghana is the first country in the world to approve a malaria vaccine
Malaria is thought to have plagued the world for at least 50,000 years. Now, for the first time, serious work is being done to create a vaccine against this terrible disease that still claims so many lives each year, especially in Africa.
Now, Ghana has become the first country in the world to approve a specific vaccine against malaria. The scientific name of the medicine is R21, and it was developed by researchers at the University's Jenner institute in Oxford.
Now the World Health Organisation is also considering approval of the vaccine, which will be produced in India, but in any case the African countries have already announced that they will 'act on their own', still mindful of the delays in the distribution of the Covid-19 vaccine.

A change for the world
Ghana is the first country in the world to approve the use of a malaria vaccine. The scientists who developed it have called it "a game changer for the whole world." Attempts to make a vaccine against this disease have been going on for a century. However, the widespread mass use of this vaccine will also depend greatly on the results of larger studies that will include 5,000 children in the near future.

What is malaria
Malaria (also known as paludism) is a parasitic disease caused by protozoan parasites of the genus Plasmodium, Kingdom Protista, Phylum Apicomplexa, Class Sporozoea, Order Eucoccidiida. Its current spread is not limited to the tropical areas of South America, Africa and Asia, but also sporadically affects the USA and other industrialised countries. Malaria is the most important parasitic disease and the second most important infectious disease in the world in terms of morbidity and mortality after tuberculosis, with more than 200 million new clinical cases per year.

The spread of malaria
As can be seen from this illustrative map, Africa is the part of the world where the danger of contracting one of the forms of malaria is highest. In fact, the dark red colour indicates 'a high risk of malaria'. Children in particular are susceptible to this disease, and especially on the African continent, where the vaccine has been approved, the lack of adequate clinical facilities over a large part of the territory makes this disease still very serious, frightening and often fatal.
The R21 vaccine
The name of the vaccine, developed by researchers at the Jenner institute at the University of Oxford, is called R21 and appears to be "extremely effective," in contrast to previous vaccines. In fact, studies have shown that this drug is up to 80 percent effective when administered in three initial doses and a booster one year later.
On whom the vaccine will be used
The official results were expected last year, but despite this they have already been shared with some government agencies and scientists, with for example the Ghana Food and Drug Authority already in possession of the data. The latter has reportedly approved the use of the vaccine in children between the ages of five months and three years.
African countries will go alone
The World Health Organisation is also taking note of this data, although it has not yet given its final approval. However, reports Prof. Adrian Hill, director of the research institute, 'African countries will decide for themselves' after falling behind in the launch of Covid-19 vaccines during the pandemic.
The goal is to eradicate the disease from the Earth
Since the first scientific studies conducted during the 1800s, so many steps forward have been made. Also Professor Hill, reported by BBC, said that "we expect 'R21 to have a major impact on malaria mortality in children in the coming years and, in the long term, contribute to the ultimate goal of malaria eradication and elimination."
The production of the R21 vaccine
The Serum Institute of India is preparing to produce between 100 and 200 million doses per year, with a vaccine factory under construction in Accra, Ghana. Each dose of R21 is expected to cost a couple of dollars. The institute's CEO, Adar Poonawalla, said Ghana's approval as the first country in the world represents a 'significant milestone in our efforts to fight malaria worldwide'.

There are various types of training depending on the results you want to achieve. If you want to lose weight, or define your muscles well after a loading period, then you need to burn a large number of calories. In addition, more and more people want to keep fit but do not have enough time to workout consistently.
Therefore, it is necessary to find ways to exercise as much as possible, burning as many calories as possible in as little time as possible. Obviously, cardio exercises are the best. Running is perfect, but it puts a lot of strain on the joints and can cause even serious problems if you do not have the right equipment (for example, the correct shoes).
We propose below a series of exercises, most also possible from home without equipment, to burn lots of calories in a short time. Remember that the number of calories burned is not absolute but depends on various factors, such as duration of exercise, pace, intensity, weight, and height. In general, the more you weigh, the more calories you will burn during exercise.

Although it is not a real certified illness, the 'impostor syndrome' counts among its patients even illustrious historical figures, such as the father of modern physics Albert Einstein. It is, in general, a low opinion of oneself and one's work, which leads to embarrassment, anxiety and sometimes outright shame, often unmotivated by the recognition received.
An expression coined in 1978, this syndrome often manifests itself in people with a university education or higher, and who hold sensitive and socially recognised roles in fields such as medicine, finance and education.
Over the years, it has been associated with a number of recurring psychological traits, and the help of a psychotherapist is essential to try to get out of it.

An international analysis has shown how humour, used as a real hospital therapy, alleviates symptoms of anxiety, stress and depression in long-term chronic patients such as children who have just undergone surgery or even elderly people in nursing homes. The research was conducted internationally and published in the journal 'Brain and Behavior'.
Basically, it was a review of the existing literature (quantitative, qualitative and mixed studies). Thus, in addition to existing papers, as many as 29 articles were included, involving 2964 participants, conducted in nine different countries, such as the United States, Australia, Italy, Turkey, South Korea, Iran, Israel, China and Germany.
The majority of patients, the study authors suggest, stated that humour therapy had positive effects in reducing anxiety and depression, compared to a small number of subjects who found this approach to be insignificant.

The vitamin B complex is a collective name for the B vitamins. They are water-soluble vitamins, necessary for the proper functioning of the metabolism.
The B vitamins are essential for providing us with the energy we need to carry out our daily activities, as well as for protecting our skin, hair and teeth, and for the prevention of certain diseases, from cardiovascular to neurological to skin diseases.
The 8 B vitamins include vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B8, vitamin B9 and vitamin B12.
What are the main sources of vitamin B? Let's find out together. (Source: humanitas.co.uk)
