Pros and cons of vaccination

The vaccination is one of the topics of heated discussions during these days.   This is in light of the fact that, although vaccination is regarded as to be one of the most important and effective methods that keep a number of dangerous diseases at bay, several studies revealed that they are not 100% risk-free. However, risks of vaccines never outweigh the risks of the diseases they prevent, especially among old, infants and pregnant women, whose immune system is very weak. All the same, having a vaccination is an individual choice or a decision of the parent.

What is vaccination?

Vaccination can be described as the method of producing a state of immunity to a certain infectious disease by introducing a weakened version of a virus or bacteria of that particular disease to one' s body. Usually, vaccination does not bring about any symptom of that disease because the pathogen that is introduced is too feeble to bring about symptoms.

What happens once the vaccination is given to a person?

Once vaccination is given to a person,  the body of the person will able to detect the virus and will start to fight against it and eliminate it from the system by producing antibodies. These antibodies make it possible for the body’s immune system to fight off the same virus in the future.  

Who all can be vaccinated?

Generally, we can say, all individuals aged 6 months and older are eligible for getting vaccinated. However, one's age, health conditions, history of allergies, and many more factors determine if one should get a particular vaccine. This is because vaccines differ in their constituents. Some of these constituents can bring about allergic reactions and other health issues. Therefore, individuals with a compromised immune system (immune system that is not capable to get rid of the infections. Example individuals with weakened immune systems, such as those with asthma, chronic illness, or undergoing treatment for cancer) are usually advised to wait till their immune system comes back to normal. People who have experienced allergic reactions to a particular vaccine are not allowed to take the follow-up doses.

What is herd immunity?

Herd immunity is a concept that highlights a view that when the vaccination of a major portion of a population takes place, they will act as a barrier to the outbreak of that particular disease. This is in the light of the fact that they will not spread the disease as they are immune to that disease. This will, therefore, effectively provide immunity for the minor portion of the population who have not taken that vaccine due to various reasons.

                                                

What are the pros and cons of vaccination?

Pros:

Vaccination prevents illness: Prevention is better than cure. Prevention of illness is one of the most significant benefits of vaccination. Vaccination helps in preventing and eradicating several life-threatening diseases.

Vaccination saves your life: People can be protected against several diseases that once injured or rubbed off thousands of the population. Many of those life-threatening diseases have been eliminated completely and others are nearing extinction all because of effective vaccines. Polio and smallpox are examples of diseases eliminated through vaccination.

Vaccination is relatively safe and highly effective: Vaccines are developed after long research and studies that covers almost all aspects of its impact on an individual's health. It also undergoes rigorous safety testing preceding the FDA approval and are continually monitored for safety. This makes vaccines safe and effective.

Vaccination protects your dear ones: Vaccination not only protects your family but also your dear ones and friends who may not be able to receive certain vaccinations due to some vital reasons like severe allergies, weakened immune systems due to health conditions like leukemia, etc. Therefore, it is important to ensure you and your family who are able to get vaccinated are fully immunized.  This not only protects your family but also helps prevent the spread of these diseases to your friends and loved ones (herd immunity).

Vaccination saves your time and money: Some vaccine-preventable diseases can result in prolonged disabilities which cannot be rectified and can take a financial toll on you looting away the money and time. Besides, It is always cheaper to prevent a disease than to treat it. Vaccination costs less when compared to the hospital charge and medication charge you need to find to treat the vaccine-preventable disease. Vaccination, thus, not only save lives, they save money too.

Cons:

Health issues with newborns: Newborns can become vulnerable to some health issues if the mothers have used intravenous vaccination. Babies are found to catch diseases like hepatitis if their mothers have been using such vaccination.

Immunity through Vaccination may not last long: Immunity through Vaccination may not stay forever as the natural immunity does. Natural immunity has a long-term, or sometime, lifelong effect on one’s body.

 There are chances of inducing toxic through vaccine: Vaccination poses a risk of inducing harmful and toxic chemicals to the body. Some people, especially, the children may react severely to these chemicals. Mercury, aluminium, and Formaldehyde are some of the chemicals that can trigger a reaction.
