What are Vaccines?

Vaccination is a simple, safe, and effective way of protecting people against harmful diseases before they come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger.

Why are vaccines so important?

Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.

Most vaccines are given by injection, but some are given by mouth or sprayed into the nose.

How effective are vaccines?

Vaccination is a safe and effective way to prevent disease and save lives. Today there are vaccines available to protect against at least 20 diseases, such as diphtheria, tetanus, pertussis, influenza, and measles. Together, these vaccines save the lives of up to 3 million people every year.

When we get vaccinated, we aren’t just protecting ourselves, but also those around us. Some people, like those who are seriously ill, are advised not to get certain vaccines – so they depend on the rest of us to get vaccinated and help reduce the spread of disease.

During the COVID-19 pandemic, vaccination continues to be critically important. The pandemic has caused a decline in the number of children receiving routine immunizations, which could lead to an increase in illness and death from preventable diseases.

 Vaccines reduce the risks of getting a disease by working with your body’s natural defenses to build protection. When you get a vaccine, your immune system responds.

1. Recognizes the invading germ, such as the virus or bacteria.

2. Produces antibodies. Antibodies are proteins produced naturally by the immune system to fight disease.

3. Remembers of the disease and how to fight it. If you are then exposed to the germ in the future, your immune system can quickly destroy it before you become unwell.

The vaccine is therefore a safe and effective way to produce an immune response in the body, without causing illness.

Our immune systems are designed to remember. Once exposed to one or more doses of a vaccine, we typically remain protected against a disease for years, decades, or even a lifetime. This is what makes vaccines so effective. Rather than treating a disease after it occurs, vaccines prevent us in the first instance from getting sick.

Vaccines work by training and preparing the body’s natural defenses – the immune system – to recognize and fight off viruses and bacteria. If the body is exposed to those disease-causing pathogens later, it will be ready to destroy them quickly – which prevents illness.

When a person gets vaccinated against a disease, their risk of infection is also reduced – so they’re also less likely to transmit the virus or bacteria to others. As more people in a community get vaccinated, fewer people remain vulnerable, and there is less possibility for an infected person to pass the pathogen on to another person. Lowering the possibility for a pathogen to circulate in the community protects those who cannot be vaccinated (due to health conditions, like allergies, or their age) from the disease targeted by the vaccine.

Herd immunity, also known as population immunity is the indirect protection from an infectious disease that happens when immunity develops in a population either through vaccination or through a previous infection. Herd immunity does not mean unvaccinated or individuals who have not previously been infected are themselves immune. Instead, herd immunity exists when individuals who are not immune but live in a community with a high proportion of immunity, have a reduced risk of disease as compared to non-immune individuals living in a community with a small proportion of immunity.

In communities with high immunity, the non-immune people have a lower risk of disease than they otherwise would, but their reduced risk results from the immunity of people in the community in which they are living not because they are personally immune. Even after herd immunity is first reached and a reduced risk of disease among unimmunized people is observed, this risk will keep falling if vaccination coverage continues to increase. When vaccine coverage is very high, the risk of disease among those who are non-immune can become similar to those who are truly immune.

Herd immunity through vaccination, not allowing disease to spread through a population, as this would result in unnecessary cases and deaths.

COVID-19, the new disease-causing a global pandemic, newly developed vaccines have demonstrated safety and efficacy against disease. The proportion of the population that must be vaccinated against COVID-19 to begin inducing herd immunity is not known.

Herd immunity is an attribute of vaccines against polio, rotavirus, pneumococcus, Haemophilus influenzae type B, yellow fever, meningococcus, and numerous other vaccine-preventable diseases. Yet it is an approach that only works for vaccine-preventable diseases with an element of person-to-person spread. As an example, Tetanus is caught from bacteria in the environment, not from other people, so those who are unimmunized are not protected from the disease even if most of the rest of the community is vaccinated.

Vaccination is safe and side effects from a vaccine are usually minor and temporary, such as a sore arm or mild fever. More serious side effects are possible, but extremely rare.

Any licensed vaccine is rigorously tested across multiple phases of trials before it is approved for use. Scientists are also constantly monitoring information from several sources for any sign that a vaccine may cause health risks.

You are far more likely to be seriously injured by a vaccine-preventable disease than by a vaccine. For example, tetanus can cause extreme pain, muscle spasms (lockjaw) and blood clots, measles can cause encephalitis (an infection of the brain), and blindness. Many vaccine-preventable diseases can even result in death. The benefits of vaccination greatly outweigh the risks, and many more illnesses and deaths would occur without vaccines.

Like any medicine, vaccines can cause mild side effects, such as a low-grade fever, or pain or redness at the injection site. Mild reactions go away within a few days on their own.

Severe or long-lasting side effects are extremely rare. Vaccines are continually monitored for safety, to detect rare events.

Scientific data shows that giving several vaccines at the same time has no negative effect. People are exposed to several hundred bacterias and viruses every day.

Scientists from around the world conduct ongoing monitoring to make sure that vaccines continue to be safe.
