How can polio be prevented?

How can polio be prevented?

Polio can be prevented by immunizing a child with approrpiate vaccination. There are currently two effective polio vaccines, the inactivated poliovirus vaccine (IPV) and the live attenuated oral polio vaccine (OPV).

What is the connection between drug abuse and drug trafficking?

There is a close relationship between drug abuse and crime. Drug abusers commit crimes to pay for their drugs and this inflicts damages to the society. Moreover, many criminals are under the influence of drugs while committing crimes. Drug trafficking is another outcome of drug abuse (1).

What is the difference between vaccine and immunization?

Vaccination: The act of introducing a vaccine into the body to produce immunity to a specific disease. Immunization: A process by which a person becomes protected against a disease through vaccination.

Is a vaccine a drug?

It is important to note that a vaccine is a drug. Like any drug, vaccines have benefits and risks, and even when highly effective, no vaccine is 100 percent effective in preventing disease or 100 percent safe in all individuals.

How do they weaken a virus for vaccines?

Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick. There are four ways that viruses and bacteria are weakened to make vaccines: Change the virus blueprint (or genes) so that the virus replicates poorly.

Is polio A virus?

Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. Polio is more common in infants and young children and occurs under conditions of poor hygiene.

What is the key symptom of polio?

Paralysis is the most severe symptom associated with polio, because it can lead to permanent disability and death.

Can you recover from polio?

People who have milder polio symptoms usually make a full recovery within 1–2 weeks. People whose symptoms are more severe can be weak or paralyzed for life, and some may die. After recovery, a few people might develop “post-polio syndrome” as long as 30–40 years after their initial illness.

Which vaccines have live viruses?

Currently available live attenuated viral vaccines are measles, mumps, rubella, vaccinia, varicella, zoster (which contains the same virus as varicella vaccine but in much higher amount), yellow fever, rotavirus, and influenza (intranasal).

What are the two types of active immunity?

There are two types of immunity: innate and adaptive.

What really caused polio?

Causes. Share on Pinterest Polio is caused by the poliovirus. The polio virus usually enters the environment in the feces of someone who is infected. In areas with poor sanitation, the virus easily spreads from feces into the water supply, or, by touch, into food.

When was polio at its worst?

In the United States, the 1952 polio epidemic was the worst outbreak in the nation’s history, and is credited with heightening parents’ fears of the disease and focusing public awareness on the need for a vaccine. Of the 57,628 cases reported that year, 3,145 died and 21,269 were left with mild to disabling paralysis.

How does a vaccine activate the body’s immune system?

A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

Are vaccines Biopharmaceuticals?

Different from totally synthesized pharmaceuticals, they include vaccines, whole blood, blood components, allergenics, somatic cells, gene therapies, tissues, recombinant therapeutic protein, and living medicines used in cell therapy.

Why was polio worse in the summer?

Each summer, polio would come like The Plague. Beaches and pools would close — because of the fear that the poliovirus was waterborne. Children had to say away from crowds, so they often were banned from movie theaters, bowling alleys, and the like.

What is the difference between a drug and a vaccine?

A way to broadly classify therapeutic interventions is through their timing in administration: Vaccines are classically administered to prevent the appearance of a medical problem, while drugs are generally administered to treat a medical problem.
