Importance Of Vaccination

Together with water purifying and environmental sanitation, vaccinations are the preventive measure that has contributed most to improving the health of the population and increasing life expectancy. The World Health Organization (WHO) estimates that vaccinations prevent 2.5 million deaths a year worldwide. In this article, we will learn more about the Importance of vaccination.

Health experts constantly campaign for vaccination to the wider community. Because, vaccination is still the most powerful way to prevent the spread of infectious and dangerous diseases that adversely affect public health.

What is Vaccination?

According to Wikipedia, vaccination is the administration of vaccines into a person’s body to provide immunity to a disease. For example, a polio vaccine is administered to provide protection against polio disease. Vaccination is also often referred to as immunization.

Vaccination is an effort to gain immunity so that the body becomes immune to attacks of diseases caused by viruses and bacteria. The level of disease protection is obtained from the proper implementation of vaccination.

What is a vaccine?

A vaccine is a drug obtained from a microorganism. When administered to a healthy person, it causes the person to produce defences against it. If in the future this person came into contact with the microorganism against which he has been vaccinated, the defences would protect him and would not suffer the disease.

Vaccines can contain attenuated living organisms, killed or inactivated vaccines, or recombinant (containing only one part of the virus that plays an important role in the disease, then multiplied).

Most vaccines protect against a specific disease, but there are also other combined vaccines that protect against more than one disease, such as the triple viral vaccine (measles, parotitis and rubella) or the DTP vaccine (diphtheria, tetanus and whooping cough).

Why are vaccines so important?

Thanks to vaccines, many infectious diseases that produced large epidemics and deaths, such as smallpox, have been eradicated a few years ago. Other diseases, such as measles or Poliomyelitis, although not completely eradicated, have significantly reduced in number of cases.

If we stopped vaccinating, these diseases could spread again among the population.

Are Vaccines Safe?

Vaccines are safe and effective. When used in healthy population and in large quantities all vaccines are subject to a very thorough evaluation and following internationally proven protocols.

Although joint efforts by the Government and various stakeholders continue to be made to reassure the public not to be afraid of being vaccinated, because the vaccine has passed clinical trials and safety and efficacy, there are a small number of people who are still reluctant to be vaccinated and still get incorrect information about vaccines.

What can happen if we don’t get vaccination?

If we do not get vaccinated and when we come into contact with the microorganism that causes the infection, we can suffer from the disease. Some of these diseases can produce major effects or even death.

In some cases, in addition to suffering from the disease, we can pass it to other people and cause an epidemic outbreak.

Can vaccines cause serious side effects?

Vaccines are very safe medicines. However, some people may experience some side effect, usually mild, such as fever, inflammation, redness or pain in the injected area. Allergic reactions to vaccines or other serious side effects are very rare.

When should we be vaccinated?

Health authorities classify vaccines into “systematic” and “non-systematic.”

Systematic vaccines are those indicated for the entire population, starting from childhood age, and  they are applied in accordance with the Systematic Vaccination Calendar.

In addition, during adulthood we must be vaccinated in the following situations:

If during childhood we did not receive a vaccine because it was not yet available (for example the hepatitis A vaccine, if we have not been in contact with the virus and we do not have antibodies; for example women of childbearing age who intend to become pregnant should be vaccinated against rubella in case they were not vaccinated during childhood)

Certain population groups should be vaccinated against influenza

Non-systematic vaccines are not included in the vaccination schedule and only certain people (children or adults) or population groups are advised to be in specific circumstances that make them more vulnerable to certain infections. For example, workers from schools or health centres, travellers, etc.

Do vaccines contain aluminium?

Vaccines contain a small amount of aluminum (0.5 mg) that is not harmful to health. Daily it is estimated that we consumet 8 mg of aluminium through our diet without causing us any problems.

Why should we vaccinate for diseases that do not occur in our environment?

Thanks to the success of vaccinations there are diseases that have been eradicated and others that are in the process of elimination. However, it is very important to continue vaccinating since otherwise these diseases could resurface. The resurgence of measles in Europe in recent years is a good example of what can happen when vaccine coverage decreases.

Is it true that vaccines produce autism?

There is no relationship between autism and vaccines. This false relationship comes from a study that was later shown to be a fraud. Methodologically correct studies have found no relationship between vaccines and autism.

Are too many vaccines administered to children during the first year of life?

No, the vaccines included in the calendar of systematic vaccinations protect against the most frequent and serious diseases, and are administered at the recommended ages and with the optimum intervals to favour a correct immune response. It is a false myth that the administration of vaccines to very young children overloads the immune system or that there are more adverse reactions.

How should health care providers communicate about vaccines?

There is a lot of research that explains communication about vaccines, and researchers are still identifying what methods work well. Communication about vaccines takes place in a variety of ways, from private conversations with doctors and nurses, to wide-scale coverage such as billboards and radio ads.

What can make communication complicated is the decisions and behaviors of parents that vary, depending on for example, the type of vaccine. This happens when parents have negative behavior about vaccines, often it is based on misinformation or emotional narratives about adverse reactions from vaccines.

So, health care providers have a challenge to correct misconceptions about vaccine risk.

There are several strategies that health care providers can use when talking about vaccinations with parents who have doubts. It is important to discuss the specific concerns of parents. Doctors should discuss vaccines from a variety of perspectives, such as the benefits of vaccination (preventing disease for a person and others), as well as the risks if not vaccinated (susceptible to disease).

Research shows that adjusting conversations to parental concerns can positively affect the relationship between healthcare providers and the elderly, and nurture trust.

Healthcare providers should include accurate information about vaccine risks in conversations. Do not avoid discussions about possible negative side effects of vaccines, as risk communication is vital.
