The body has an immune system that protects it from pathogens and other infections. The system is efficient, but some pathogens can overwhelm it, causing serious illnesses. Vaccination is a way to teach the immune system to fight these pathogens before it is exposed. It means that vaccination prevents people from contracting specific diseases in the future.

Today, vaccination has become a rite of passage because most people are vaccinated at a tender age. However, not many people know the essence of these vaccines nor how they work. Some do not even know what to look out for before getting vaccinated.

1. How do Vaccines Work?

The immune system is designed to protect the body against pathogenic invaders. It comprises several types of cells that are designed to remove pathogens and recognize dangerous invaders. Vaccines are developed to help the body’s immune system recognize new invaders. It stimulates the body to produce antibodies against the new pathogens. They also ensure that the body’s immune system remembers the new pathogens if they attack the body again in the future.

Vaccines are developed to expose the body to a safe version of the new disease. They take various forms, such as:

Proteins that are similar to the genetic makeup of the pathogen
A pathogenic toxoid
An inactive pathogen
A dead pathogen

The body responds to the vaccines and initiates its immune response to fight the infection.

Vaccines are administered through injections, and they contain the antigen and the adjuvant. The adjuvant sends a message to the immune system to initiate the body’s immune response, helping it build immunity.

2. Who Ensures that Vaccines are Safe?

A vaccine must undergo various tests before it is approved in the United States. The CDC and FDA are the two organizations tasked with approving vaccines in the United States. The Food and Drug Administration (FDA) analyzes the various clinical studies conducted on the vaccines. These two organizations also evaluate the environment where the drug was manufactured.

The CDC and FDA continue to assess the vaccines after they have been approved. They must ensure that the vaccines do not have any severe side effects.

3. Are Vaccines Safe?

All vaccines are safe because they have been passed through various tests before they are disbursed. They must also undergo human trials to determine their effectiveness. The overwhelming research done on vaccines shows that they are safe and effective. For example, the new covid-19 vaccine is safe, and the FDA has approved it despite undergoing various tests in less than a year. People who refuse to get vaccinated are at risk of contracting different diseases. Their illness might be worse than the vaccines’ side effects.

4. How Effective Are Vaccines?

Vaccines are very effective, but they cannot be 100% effective. The effectiveness of each vaccine is different because each one requires ingredients.

For instance, flu vaccines effectively lower infections to as low as 40% to those who receive it. It may sound low, but these vaccines are designed to match the flu strain that sometimes is different in every season.

For the measles vaccine, it is 98% effective. Most childhood vaccines are 85 to 95 percent effective, and they must match the World Health Organization (WHO) standards.

5. What Are the Side Effects of Vaccines?

It is common for vaccines to have side effects. However, most side effects are mild, while others experience no side effects. The most common side effects include fever, fatigue, seizures, muscle weakness, memory loss and pain.

However, various risk factors increase the risk of experiencing these side effects. They include:

A weak immune system
Being sick when the vaccine is being administered
Having a family history of vaccine reactions

There are no life-threatening side effects of vaccines, and most people have a higher chance of contracting diseases if the appropriate vaccine is not administered.

6. What Are the Advantages and Disadvantages of Getting Vaccinated?

Vaccination has its advantages and disadvantages that help someone to decide whether to get it or not.

Advantages

They protect people from dangerous diseases that can lead to their deaths.
All vaccines are safe and effective. The FDA ensures that any vaccine administered to a patient is effective and does not aggravate their condition.
Vaccines also protect other people, especially those who cannot be vaccinated.

Disadvantages

People experience allergic reactions to the vaccine. They are developed using different elements, and each of these elements can affect someone differently.
Someone can still become sick even after getting vaccinated.
People with a lower immune system cannot be vaccinated.

Vaccines are essential, and if someone is not vaccinated, they are at risk of contracting diseases. The FDA and CDC are in charge of approving all vaccines, making them safe. Most vaccines are effective, despite them having several side effects. Each person should be vaccinated, but they must consult a doctor before the vaccine is administered.
