[FYI] How Vaccines Work



A vaccine is a biological preparation that provides active acquired immunity to a particular disease. They help you develop immunity without getting sick first. They prepare the body to fight disease without exposing it to disease symptoms.

Post Information:

Below post has been circulating on social media.


A viral message on social media claims that children up to the age of five should not be administered the oral polio vaccine, owing to a stain of contaminated virus being found in some batches of the vaccine.

The message reads:

“News on TV says that tomorrow do not give polio dose for kids up to 5 years as some virus has been found in them, and the owner of the company who manufactures it has been arrested by the police. Inform everyone in family as well as those who have babies. Do not give oral polio dose to the baby till next update.”



Vaccines are a way to prepare your immune system against a virus. For example a Polio vaccine will have the Polio Virus in it, but the virus will be an inactive or weakened virus so that it cannot harm the body. The immune system however gears up to protect the body from the virus hence the body’s immune system will be proactively ready to fight any active virus of the same kind which may happen to enter the body.

The immune system is the body’s natural defense against germs. When a germ invades, the immune system sends special cells to fight it off. Sometimes, though, the immune system is not naturally strong enough to prevent a disease from seriously harming someone or even killing them. But there is a way to give the immune system a boost. That is where the Vaccine is given either orally or is injected. Before Vaccines, lot of children suffered from killer deseases such as measles, polio, smallpox and diphtheria. Tetanus is a very common vaccine we take to prevent us from getting affected by the virus. These vaccines have saved us from many deadly deseases like measles, diphtheria and few others.

An infectious viral disease that affects the central nervous system and can cause temporary or permanent paralysis. Mostly known as poliovirus. The virus is spread person to person, typically through contaminated water. It can attack the nervous system, and in some instances, lead to paralysis. A virus that may cause paralysis and is easily preventable by the polio vaccine.

Extremely rare: Fewer than 5 thousand cases per year (India)

– Preventable by vaccine
– Treatment can help, but this condition can’t be cured
– Spreads through contaminated food or water
– Requires a medical diagnosis
– Lab tests or imaging always required

According to the World Health Organization (WHO), 1 in 200 polio infections will result in permanent paralysis. However, thanks to the global polio eradication initiative in 1988, the following regions are now certified polio-free:

  • Americas
  • Europe
  • Western Pacific
  • Southeast Asia

The polio vaccine was developed in 1953 and made available in 1957. Since then cases of polio have dropped in United States. Read more here

Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types of vaccines used are: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV).

In a generic sense, vaccination works by priming the immune system with an ‘immunogen’. Stimulating immune response, by use of an infectious agent, is known as immunization. The development of immunity to polio efficiently blocks person-to-person transmission of wild poliovirus, thereby protecting both individual vaccine recipients and the wider community.

The development of two polio vaccines led to the first modern mass inoculations. The last cases of paralytic poliomyelitis caused by endemic transmission of wild virus in the United States occurred in 1979, with an outbreak among the Amish in several Midwest states. The World Health Organization recommends all children be fully vaccinated against polio.

Worried About the News of Contaminated Polio Vaccines?

(Oct 2018) P2 stains post is circulating around Whatsapp cautioning others about Vaccine, whereas we should not get into panic situation and spread half known information about the search. Many posts under various headings are in circulation regarding this issue. Ministry of health is taking care of all this. As parents we tend to believe such information. Situation is under control. Please dont worry about it. Dont get feared about it. Read more


“The recipients of such vaccine will usually shed the vaccine virus through fecal route for about 4-6 weeks after which it will die down. In small areas where such vials were used, polio surveillance in the environment and through stool collection has been significantly enhanced by MoHFW, with support from WHO and partners to keep constant vigil on the shedding of the polio vaccine virus”
