Track 8: vaccine
What is vaccine?
Vaccines a straightforward, safe, and efficient method of preventing against dangerous diseases before they are contracted. It utilises the body's own defences to develop resistance to certain pathogens and strengthens the immune system.
Vaccines condition the immune system to produce antibodies, exactly as it does when exposed to a disease. Vaccines include only inactivated or weakened versions of pathogens, such as viruses or bacteria, so they do not cause disease or increase the risk of its complications.
How does vaccine work?
Vaccines lessen the likelihood of contracting a disease by bolstering the body's natural defenses. When you acquire a vaccine, your immune system responds. It:
- Identifies an invading pathogen, such as a virus or bacteria.
- Produces antibodies. Antibodies are proteins that the immune system produces spontaneously to fight disease.
- Recalls the sickness and its treatment. In the event that you are exposed to the pathogen in the future, your immune system can promptly eliminate it before you become ill.
Therefore, the vaccine is a safe and ingenious technique to generate an immune response in the body without producing illness.
Our immune systems are intended to recall. Once exposed to one or more doses of a vaccine, protection against a disease often lasts for years, decades, or a lifetime. This is the reason why immunizations are so effective. Rather of treating an illness after it occurs, vaccines protect us from being ill in the first place.
Why should I get vaccinated?
Diseases like measles, meningitis, pneumonia, tetanus, and polio pose a danger of severe illness and disability in the absence of immunizations. Many of these disorders are potentially fatal. WHO estimates that immunizations for children alone save approximately 4 million lives annually.
Although some diseases have become uncommon, the pathogens that cause them continue to circulate in some or all regions of the globe. Today, infectious diseases can readily transcend international borders and infect anyone who is unprotected.
Two primary reasons to get vaccinated are for our own protection and for the protection of people around us. Because not everyone can be vaccinated, including very young infants, people who are gravely ill, or those with severe allergies, they rely on others getting vaccinated to protect them from vaccine-preventable illnesses.
What diseases do vaccines prevent?
Vaccines offer protection against numerous diseases, including:
•Cervical cancer
•Cholera
•COVID-19
•Diphtheria
•Ebola virus disease
•Hepatitis B Virus Vaccine
•Measles Japanese encephalitis
•Meningitis \Mumps
•Pertussis
•Pneumonia
•Polio \Rabies
•Rotavirus
•Rubella
•Tetanus \Typhoid \Varicella
•Viral fever
Several other vaccinations, including those that protect against the Zika virus and malaria, are now being developed or tested, although they are not yet widely available worldwide.
In your country, not all of these immunizations may be required. Some vaccines may only be administered prior to travel, in high-risk areas, or to those in high-risk vocations. Consult your healthcare provider to determine which immunizations you and your family require.

Are vaccines safe?
Vaccination is risk-free, and any adverse reactions are typically modest and transient, like a painful arm or a low-grade fever. Though they are relatively rare, more severe side effects are conceivable.
Before being authorised for use, every licenced vaccine undergoes extensive testing over several trial phases, and it is routinely reviewed after being made available. Additionally, researchers are continually looking at data from many sources for any indication that a vaccine may have negative health effects.
Remember, a vaccine-preventable disease is much more likely to cause serious harm to you than a vaccine. For instance, measles can result in encephalitis (a brain infection), which can result in blindness, while tetanus can result in severe pain, muscle spasms (lockjaw), and blood clots. Numerous diseases that are prevented by vaccination can potentially be fatal. Without vaccines, there would be a lot more illnesses and fatalities because the advantages of vaccination far outweigh the risks.
