Vaccination is protection to people against various types of diseases. It prevent diseases, thereby prevent sickness or illness. For e.g. Covid Vaccination. In most cases, these diseases are dangerous and may even prove to be fatal. Vaccines are different in comparison to most medicines that treat or cure diseases.
In the field of medicine, the use of terms vaccines, vaccination, and immunizations often takes place. Vaccination is the act when a medical professional introduces a vaccine into the body. Immunization, on the other hand, refers to the process by which protection is given to an individual against dangerous types of diseases. The terms vaccination and immunization take place in an interchangeable manner. Vaccination and immunization are very important concepts for the welfare of humanity. More and more types of vaccines keep on coming up, thanks to advancements in the field of medical science.
Introduction to Vaccination
Vaccination and immunization is a global health success story. This is because the process of vaccination has led to saving millions of lives all over the world. For example, polio vaccination for babies has caused a massive downfall in this disease.
How do vaccines reduce the risks of the disease? Vaccines work with the natural defenses of the body to build protection. When you get a vaccine, a response takes place by your immune system.
As of now, vaccines help in the prevention of more than twenty life-threatening diseases. Vaccination helps people, belonging to all ages, to live longer and healthier. Vaccination and immunization are preventing up to 2-3 million deaths on an annual basis.
Immunization is an important part of primary health care. It prevents some of the most deadly diseases like influenza, diphtheria, measles, tetanus, and pertussis.
Due to its immense importance, many term it as an indisputable human right. It is one of the best health investments you can hope to purchase with money. Vaccines play a crucial role when it comes to the prevention and control of deadly outbreaks.
Unfortunately, despite the significant progress in the field of vaccination, a huge number of people around the world lack access to vaccines. In some countries, the situation is so bad that they have gone reverse on vaccination. Complacency may be responsible here and it may ruin all the part efforts.
Vaccines work by artificially activating the body’s immune system. This way, the protection of the body takes place against infectious diseases. Moreover, an immunogen causes activation by priming the immune system.
Immunization refers to the stimulation of the immune responses with an infectious agent. Furthermore, there are various ways of administering immunogens under vaccination.
Most administration of vaccines takes place before a patient gets a disease. This administration helps in increasing future protection. However, the administration of some vaccines takes place after the patient gets a disease.
For example, vaccines are administered after exposure to smallpox. This way, it either offers some protection from smallpox or diminishes the severity.
Louis Pasteur was the one to give the first rabies immunization to a child. A rabid dog had bitten this child.
Since its discovery, the rabies vaccine has been tested to be effective against rabies in humans. Its effect used to take place after its administration several times over 14 days. This administration took place along with rabies immune globulin and wound care.
Other notable vaccines examples include experimental AIDS, Alzheimer’s disease vaccines, and cancer. The aim of such immunizations is to trigger an immune response. Moreover, this response is more rapid and with fewer risks than natural infection.
Types of Vaccine
A vaccine chart would include various types of vaccines. Below are the several types of vaccines:
- Live-attenuated vaccines: They use a germ in a weakened form.
- Inactivated vaccines: They use a germ’s killed version.
- Subunit, recombinant, polysaccharide, and conjugate vaccines: Such vaccines use only germ’s particular pieces, like its casing, protein, and sugar.
- Toxoid vaccines: Their preparation takes place with a toxin made by the germ.
- mRNA vaccines: Such vaccines use messenger RNA. The messenger RNA provides instructions to the cells for how to make a germ’s protein.
- Viral vector vaccines: Such vaccines use genetic material. They provide instructions to the cells for making a germ’s protein.
Importance of Vaccination
The following points demonstrate the importance of vaccination:
- Saves lives: Experts recommend vaccines for infants due to their underdeveloped immune systems. This way vaccination help in protecting the lives of children.
- Prevents dreadful diseases: Vaccines prevent illnesses that are deadly in nature which can lead to severe problems. For example, polio can lead to paralysis, amputations, and may even prove fatal.
- Saves money: The cure of diseases can be very costly. Therefore, it is better to undertake vaccination before contracting these diseases. This is better rather than going through expensive medical treatment later on.
- Vaccines are safe: All the vaccines today, generally speaking, are reliable and safe for your child. In very rare cases, there may be a side effect of a vaccine. The chances of protection are much higher than in comparison to that of a side effect.
- Eradicates diseases: Vaccinations protect others besides the ones getting the vaccines. With a proper vaccination drive, a lot of deadly diseases will be eliminated in the future. For example, vaccinated children can help protect their siblings and friends from diseases.
- Vaccines help in the long run: When vaccination takes place, the immune system becomes really strong to fight germs. This way, a person does not fall prey to diseases so easily. Consequently, vaccination helps in the long run.
FAQs on Vaccination
Question 1: Are vaccines safe to be applied?
Answer 1:Vaccines are, generally speaking, safe for application. The determination of the safety of a vaccine takes place through extensive safety testing and evaluation. Once this happens, a vaccine becomes approved for public usage.
Special care is essential when it comes to vaccination for babies.
Question 2: What is meant by a vaccine schedule?
Answer 2: A vaccine schedule is a vaccine chart that lists the recommended vaccines for different groups of people. Furthermore, it also includes who are supposed to get the specific vaccines. Moreover, the required number of many doses they need is also a part of the vaccine schedule.
Question 3: What do you understand by community immunity?
Answer 3: Community immunity refers to the concept that vaccines facilitate in keeping the communities healthy. Normally, germs tend to travel quickly through a community and this way sickness can spread. An outbreak happens when a massive number of individuals fall prey to illness.
However, when the vaccination of enough people takes place against a certain disease, it’s harder for it to spread. This type of protection is what experts call as community immunity.
