anti-vaxxers common anti vaccination arguments

Why do I need vaccinations if you already have them?

The short answers to this are:

  • Herd Immunity
  • Immunocompromised (EG Cancer patients undergoing Chemo)
  • Carrying illnesses

Herd Immunity

Herd immunity (also called herd effect, community immunity, population immunity, or social immunity) is a form of indirect protection from infectious disease that occurs when a large percentage of a population has become immune to an infection, thereby providing a measure of protection for individuals who are not immune. In a population in which a large number of individuals are immune, chains of infection are likely to be disrupted, which stops or slows the spread of disease. The greater the proportion of individuals in a community who are immune, the smaller the probability that those who are not immune will come into contact with an infectious individual.

Anti-vaxxers are doing vast damage to our herd immunity. This in turn is allowing completely preventable diseases to return. This is also damaging for those who are immunocompromised/immunosuppressed.

Immunocompromised: having an impaired immune system.

Immunosuppressed: Deliberately induced immunosuppression is generally done to prevent the body from rejecting an organ transplant, treating graft-versus-host disease after a bone marrow transplant, or for the treatment of auto-immune diseases such as rheumatoid arthritis or Crohn’s disease.

Patients who are undergoing treatments such as chemotherapy have an impaired immune system.  An Immunocompromised person may be particularly vulnerable to opportunistic infections, in addition to normal infections that could affect everyone.

Anti-vaxxers have put many people in danger due to the misinformation they have spread.


An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has contracted an infectious disease, but who displays no symptoms. Although unaffected by the disease themselves, carriers can transmit it to others.

Any person you meet could be carrying any number of communicable diseases without displaying symptoms themselves. Therefore it is wise to have vaccinations for everything that is preventable.

Catching the Virus is better than immunisation (Pox Parties/Virus Parties)Anti-Vaxxer Measles

At one point to help build immunity people used to hold things like “Chicken Pox Parties” to ensure their kid got chickenpox when they were young. Chickenpox is very dangerous for adults but generally (as in not always) quite safe for children.

However, paediatricians have warned against holding pox parties, citing dangers arising from possible complications associated with chickenpox, such as encephalitis, chickenpox-associated pneumonia, and invasive group A strep. Although such complications are not common, they can cause brain damage or death. Before the chickenpox vaccine became available there were 100 to 150 deaths from chickenpox among children in the U.S. annually.

Would you rather go the anti-vaxxer route and risk your child’s death, or take a perfectly safe vaccine?

Other viruses like the measles or mumps are far more dangerous. Consider for a moment what you would like done to you. Take a vaccine which is proven to be safe and work, or follow the anti-vaxxers and risk death and/or deformity.

Imagine if we applied this to other areas of our life. Let’s infect our computers with loads of viruses so they can build natural immunity!*


*Of course, this is an absurdism, computers do not build immunity whereas humans do, however, consider it this way.

Operating systems (OS) can and do change to help prevent various trojans and viruses, this takes a programmer to actually implement these things, but that is similar to your body’s response.

We also have a digital form of a vaccine, in the case of antivirus software, along with anti-malware, firewalls etc. These companies have a primary focus of protecting your computer from these nasty bits of code, and it can take much longer for the OS to be coded in a more protective way.

This is basically the vaccine and the immune response explained. The vaccine gives you more instantaneous protection, your immune system takes time to respond. Like a computer, much damage can be done if there is no protection in there in the first place.

  • Thanks Jared, for pointing out that my absurdism might be lost on some and should be expanded on!
