What is vaccine and vaccination??
Vaccination is an safe, and effective way to protect people from harmful bacteria before they become infected. It strengthens the immune system by activating our body's own antibodies to create resistance to specific diseases. A Vaccines can save millions of lives each year. Vaccines work by training and preparing the body’s natural defences to recognize and fight off the viruses and bacteria they target. Vaccines train our 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 people at risk of its complications.
How the vaccines work?
When we get a vaccine, our immune system responds and will recognizes the invading germ, such as the virus or bacteria. After that our immune system produces antibodies. This antibodies are proteins produced naturally by the immune system to fight disease. Lastly, our immune system will remembers the disease and how to fight it. If we are then exposed to the germ in the future, our immune system can quickly destroy it before we become unwell.
Vaccines is important to take?
During the COVID-19 pandemic, vaccination continues to be critically important. 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. 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.
Who can take this vaccines?
Community who can vaccinated
Nearly everyone can get vaccinated. However, because of some medical conditions, some people should not get certain vaccines, or should wait before getting them. These conditions can include:
Chronic illnesses or treatments (like chemotherapy) that affect the immune system;
Severe and life-threatening allergies to vaccine ingredients, which are very rare;
If you have severe illness and a high fever on the day of vaccination.
These factors often vary for each vaccine. If you are not sure should get a particular vaccine for you and your family, you may conduct with doctor or health worker.
If you have questions about vaccines be sure to talk to your healthcare worker. He or she can provide you with science-based advice about vaccination for you and your family, including the recommended vaccination schedule in our country, Malaysia.
Are there side effects from vaccines?
Vaccination is safe and side effects from a vaccine are usually minor and temporary. 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 adverse events.
All the ingredients of a vaccine play an important role in ensuring a vaccine is safe and effective. Some of these include:
The antigen. This is a killed or weakened form of a virus or bacteria, which trains our bodies to recognize and fight the disease if we encounter it in the future.
Adjuvants, which help to boost our immune response. This means they help vaccines to work better.
Preservatives, which ensure a vaccine stays effective.
Stabilisers, which protect the vaccine during storage and transportation.
Vaccine ingredients can look unfamiliar when they are listed on a label. However, many of the components used in vaccines occur naturally in the body, in the environment, and in the foods we eat. All of the ingredients in vaccines – as well as the vaccines themselves - are thoroughly tested and monitored to ensure they are safe.
