Decode 7 misconceptions people often think about vaccines

Turns out, vaccination is not only for yourself, but also for social responsibility.

An anti-vaccine person can store in their heads a series of 'scientific' arguments, to persuade someone to oppose their vaccinations. The tactic of these people is to touch emotions, spread unfounded fear of vaccines.

If not equipped with real scientific knowledge, perhaps many people will nod when they hear that the vaccine is a pathogen, they also contain aluminum and so the vaccine will be harmful.

But is it true? Let's decipher 7 anti-scientific perspectives that most anti-vaccine people talk about:

1. Vaccines are toxic because they contain "dangerous" chemicals like MSG, anticoagulants, phenol, formaldehyde, aluminum and lead?

In fact, toxicity is a quantitative concept, meaning it is determined by the dose and not the chemical itself. Only the dose that is sufficient to cause toxicity of substances is different.

For example, the filtered water also has toxicity, if you drink to a dose of 5 l / day, it will cause even hyponatremia. The more dangerous substances have a stronger toxicity, just because their toxic doses are lower. For example, with mercury, at a dose of 1mg / m3 the air is toxic.

Although there are many vaccines that contain chemicals such as aluminum, mercury and formaldehyde, the dosages of these chemicals are very small and small below toxic levels.

For example, the vaccine contains a small amount of aluminum to help make the shots more effective. But the dose of aluminum contained in a vaccine is only 0.125 mg, much lower than the daily safe consumption of 30 to 50 mg.

Mercury was once used, but since 2001, it has been removed from most vaccines for children.

2. Can the vaccine have the opposite effect, making you infected?

The vaccine does not weaken your immune system. As its definition, the vaccine boosts the immune system, and anything that can boost the immune system is called a vaccine.

Usually, the vaccine will contain a form of inactivated pathogen (not likely to cause disease). It is injected into the body to train the immune system to identify this pathogen, and to develop mechanisms to protect the body and fight off real germs in the future.

Anti-vaccine people often argue that older people and children are weak immune systems, so they can get the disease soon after the vaccine is injected into the body. But in reality, the elderly and children are the ones who need to be protected with the most vaccine, because their immune systems are vulnerable.

3. Allergic vaccines?

In 1997, scientists began to question whether the vaccine could cause allergies. Research since then has yielded a strong result, claiming that the vaccine has the opposite effect: they protect you from allergies.

4. Vaccines are not so effective that they are worth injecting into people

A birth vaccine can quell a pandemic, prevent millions of people, save their lives and risk permanent disability because of illness.

For example, a pandemic of smallpox in the 1960s caused millions of deaths. But only two decades later, smallpox was almost wiped out because of the vaccine. Today, it has been completely wiped out all over the world.

5. Vaccines that cause autism?

In the 1990s, a published scientific article showed the association between vaccines against measles, mumps and rubella (MMR). However, this study was later proven to be fraudulent. Many scientists have conducted many long-term and comprehensive studies to refute the relationship between vaccines and autism.

In addition, 10 of the 13 authors of the article from the 1990s rejected and retracted their original claims.

6. Is vaccination only a self-interest, not vaccination?

The vaccine not only protects your friends, but also helps protect the community, especially 2-5% of the weakest population. For example, as a cancer chemist, they cannot get the vaccine, but thanks to all the people around them who have been vaccinated, the germs cannot spread to them.

This is called population immunity, and it affects people's health - not just you. All healthy people are responsible for full immunization, because if the rate is increased to 95-98%, we will protect 2-5% of the most vulnerable population.

7. Are pharmaceutical companies hiding something dangerous to make money from vaccines?

Of course, pharmaceutical companies make money from vaccines, but that doesn't mean they have to hide something dangerous. In the United States, between 1994 and 2013, the vaccine saved for direct health care costs of $ 295 billion, and $ 1.3 trillion in social costs.

The pharmaceutical industry has been involved in many scandals related to concealing the side effects of drugs, but the vaccine is one of the medical tools with the highest protective effect on humans. A vaccine from research to use can take 10 to 25 years. After that, it continued to be carefully monitored.

In fact, the chance of you reacting to MMR vaccine is 1 / 1,000,000, 10 times lower than your chance of being struck by lightning. Clear odds give you an advantage, so vaccinate as needed.
