What Are The Most Dangerous Vaccines That You Should Know?


What is it? This viral infection targets the respiratory system and affects your lungs. Being air-borne, this virus can easily last on surfaces touched for up to 2 hours. Measles can also cause a number of conditions including pneumonia, brain swelling, and even death.

Vaccination: The Measles vaccine is known as the MMR vaccine. It protects you from three diseases namely measles, mumps, and rubella. Children usually get two doses of MMR vaccine – the first one in between 12 and 15 months, and, the second one between 4 and 6 years of age.


What is it? Polio is known for affecting the body muscles. According to studies, the virus usually stays in the intestine and can cause infection via the infected person’s feces. Being one of the most dreadful diseases that the world has ever seen, Polio can cause brain infection and even paralysis.

Vaccination: The Polio vaccine is known as the Oral Polio Vaccine (OPV). It creates serum immunity in the body and protects the sufferer from polio paralysis. According to WHO, the first OPV dose should be initiated at birth. Furthermore, 3 OPV doses should be administered along with 1 IPV dose.

Pneumococcal Disease

What is it? It is one of the life-threatening diseases that the human race has ever come across. This bacterial disease can lead to a number of conditions such as pneumonia, meningitis, ear infections, etc. One can get this kind of infection by coming in direct contact with mucus or saliva of the infected person. This virus can create deadly consequences in people older than 65 years.

Vaccination: Both PCV10 and PCV13 are used for preventing Pneumococcal Disease. According to WHO, infants should be given three doses at 2,4 and 6 months of age. As they grow, they can also be given a booster in between 9 and 15 months. Individuals older than 50 years of age are administered PCV13.

Meningococcal Disease

What is it? This bacterial disease is easily spread through kissing or living with someone who is already infected. In these cases, the bacteria usually live in the back of the nose and throat of the infected person. Not only can it cause meningitis but it also can result in swelling of the brain and spinal cord. Common symptoms include headache, stiff neck, fever, etc.

Vaccination: Both MenACWY and MenB are used to treat this bacterial disease. MenACWY is usually administered to teens between 11 and 12 years of age. A further booster dose is recommended when these teens turn 16 years. Young adults are often given MenB between 16 and 23 years of age.

Hepatitis B 

What is it? This viral infection attacks the liver and slowly turns into chronic liver disease. It can be easily transmitted by the people already suffering from the virus. Since the virus is present in the blood, it can spread through blood contact or via sex. According to a study, Hepatitis B is more dangerous and infectious than HIV. This infection can result in life-threatening liver diseases including liver cancer.

Vaccination: The Hepatitis B vaccine is highly recommended for infants up to 18 years of age. Doctors often prescribe a three-dose Hepatitis B vaccine schedule. This schedule includes the first dose at birth, second dose after a month of the first shot, and a third dose after four months of the first shot.


What is it? Mumps is another deadly disease that is caused by a life-threatening virus. People suffering from Mumps often end up having fever, muscle aches, swollen glands, and headache. An individual can get the virus by breathing the air in which an individual suffering from Mumps has coughed. Mumps may lead to a number of health problems including sterility and deafness.

Vaccination: The MMR vaccine protects you from Mumps. Doctors recommend two doses of MMR vaccine i.e. in between 12-15 months and the second one between 4-6 years of age.

Haemophilus Influenzae Type B (HIB) 

What is it? HIB is a bacterial disease that is caused by HIB bacteria. While this disease primarily targets the lungs, it can also affect the lungs, spinal cord, joints, and blood. People usually get the virus by breathing the same air in which the people with HIB have coughed in. Children are more prone to catch the virus because of their weak immunity.

Vaccination: HIB vaccines are more effective when administered during infancy. According to WHO, Hib conjugate vaccines should be part of every infant immunization program across the world.

These are some of the most life-threatening diseases that the world has ever seen. However, with proper vaccination on schedule, it is not challenging to get rid of these diseases. Coronavirus deserves a special mention here because of its contagious nature and widespread effect across the globe. However, no virus has been discovered to date.
