Worldwide vaccination practices have become more and more efficient. Currently, the World Health Organization estimates that regular vaccination prevents between 1 and 3 million deaths per year. The global measles rate has plummeted by 80%. However, alarmingly 19.4 children across the globe have not received vaccines before the age of one.
A growing trend has left some children and adults who can not receive vaccines at risk. Thankfully global vaccination is on the rise and many highly contagious and deadly diseases are more under control than ever If you're wondering which vaccines are most common worldwide keep reading to find out.
Measles is an extremely serious viral infection. It's highly contagious and can cause encephalitis, blindness, and death. In 2018 86% of children globally had received their first dose of this important vaccine. The WHO reports that 171 countries have included a second dose in their routine immunization. Measles can cause lifelong brain damage or even be fatal. It's especially dangerous in small children and infants. This life-saving vaccine is incredibly widespread protecting most children from infection.
Mumps is a highly contagious viral disease. It causes painful swelling of the parotid glands on the lower side of the face. Mumps can also cause other uncomfortable symptoms such as fever and stomach ache. There is a persistent myth that mumps causes infertility in men but that is not true. Current estimates are that more than 90% of children receive at least one dose of the combination vaccine MMR which protects them against mumps. The virus can cause serious long term effects including hearing loss and problems with coordinating movements. Without proper vaccination children are left at risk for lifelong complications.
The Diptheria-Tetanus-Pertussis vaccine is one of the most commonly administered vaccines worldwide. According to the World Health Organization, 116.3 million infants (nearly 80% of the babies on earth) had received 3 doses of this lifesaving vaccine. They also reported that 129 countries had reached 90% coverage of the DTP3 vaccine. Diptheria in infants can present itself in multiple ways including a skin infection and a respiratory infection.
Either as a skin rash with open sores or a respiratory infection. It was very common in the 1920s before the vaccine was widespread. Pertussis is the proper name for whooping cough. Whooping cough is extremely infections and can be deadly to infants. Tetanus is a potentially life-threatening bacterial infection that can cause nerve damage and causes severe muscle spasms. The widespread use of DTP3 saves countless babies from unnecessary suffering and prevents many deaths.
8 Hepatitis B
By the end of 2018 Hepatitis B vaccines had been introduced in 189 countries. Worldwide coverage of the vaccine is pretty high with some estimates as high as 90%. Hepatitis B is a viral infection that damages the liver. 42% of infants born receive their first dose of this vaccine within 24 hours of birth. The infection is very serious, particularly for small children. It can lead to liver disease and even cancer later in life. Hepatitis B can become a chronic condition.
Polio is one of the most dangerous infections on this list. It's highly contagious and ravages the body causing irreversible paralysis. The tragic illness once devastated the world's children but thanks to vaccines it's now nearly eradicated.
In 2018 85% of the world's infants were vaccinated against this horrific illness. Polio has been completely eradicated in all countries except Afganistan, Nigeria, and Pakistan but all countries remain at risk of imported infection until it's been completely eradicated.
This vaccine's coverage varies from region to region but is widespread. 72% of children worldwide receive 3 doses of this vaccine before 1 year of age. The vaccine is administered in 191 countries according to The World Health Organization. Some regions have very high rates of Hib inoculation such as the Americas and Southeast Asia. 87% of children in these regions receive their Hib vaccine. Only 27% of children in the WHO Western Pacific region receive theirs.
5 Meningitis A
Meningitis A is an extremely serious infection that causes brain damage and can be fatal. The disease ran rampant in several African countries. In 2010 the ManAfriVac vaccine was introduced to the field. It was developed by the WHO, the PATH Meningitis Vaccine Program and The Institute of India. Since the introduction of the vaccine, over 300 million people have been inoculated against this deadly disease.
Rubella is a viral infection that is very serious for pregnant women. While younger kids can bounce back from rubella it can cause fetal death or pass down congenital rubella syndrome which can lead to defects of the heart, eyes, ears, and brain.
By the end of last year, the vaccine was routinely given in 168 countries. Worldwide coverage has been estimated at 69%. It's incredibly important for pregnant women to be protected from this virus to protect their unborn child.
3 Pneumococcal Diseases
This group of infections includes meningitis, bronchitis, sinusitis, pneumonia, febrile bacteremia, and otitis media. Many of these infections can be fatal for young children. They can also cause organ damage and chronic issues. Children are vaccined against these infections in 145 countries. Their total coverage is estimated worldwide is estimated at 45%.
2 Yellow Fever
Yellow Fever is an easily transmitted viral infection passed to humans via mosquitos. The infection is acute and hemorrhagic. 40 countries are vulnerable to the infection. 36 of them routinely inoculate infants against the infection with a coverage estimate of 49%. The virus is present on all continents. It spreads easily in densely populated or urban areas. A single dose of the yellow fever vaccine provides lifelong protection.
Rotaviruses are the most common cause of diarrhoeal disease in small children worldwide. 101 countries worldwide innoculate against Rotavirus with a coverage of 35%. Diarrhoeal disease is a major problem for infants and small children alike. They're one of the leading causes of death among children under 12 worldwide. Particularly in countries with developing sanitation, these vaccines are vital to the children they protect. Children in developed nations are also at risk of rotaviruses. Protection against these potentially serious illnesses is important for every child.
