Can COVID-19 Vaccination Damage Our Immune System?

Does COVID-19 vaccination permanently damage our immune system, and prevent us from getting protection against other viruses?

Take a look at the viral claim, and find out what the FACTS really are!


Claim : COVID-19 Vaccination Damages Our Immune System!

A WhatsApp message has gone viral, claiming that the UK government has admitted that COVID-19 vaccination permanently damages our immune system!

The claim is rather long, so just skip to the next section for the facts…


UK Government admit that the vaccines have damaged the natural immune systems of the double jabbed.

The British government has spilled the beans about that fact that once you get double jabbed, you will never again be able to acquire full natural immunity against Covid variants – or possibly any virus.

So let’s watch the ‘real’ pandemic begin now!


Truth : COVID-19 Vaccination Will NOT Damage Immune System

This is yet another example of FAKE NEWS created by anti-vaxxers to scare people, and here are the reasons why…

Fact #1 : UK Government Did Not Say Vaccines Damage Immune Systems

The UK government did not say that “vaccines have damaged the natural immune system of the double jabbed“. That is a complete lie.

Fact #2 : COVID-19 Vaccination Boosts Natural Immunity

The claim that COVID-19 vaccination prevents “full natural immunity” against COVID-19 variants is NONSENSICAL.

COVID-19 vaccination may provide different levels of protection for different variants, but it does NOT prevent you from gaining “full natural immunity”, if you get infected anyway.

In fact, it is YOUR OWN immune system that makes those antibodies, not the COVID-19 vaccination. That’s your natural immunity at work.

COVID-19 vaccination only kickstarts the process, so you will have those antibodies before you get infected.

Fact #3 : COVID-19 Vaccination Do Not Prevent Immunity From Other Viruses

The claim that COVID-19 vaccination prevents you from acquiring full natural immunity from other viruses is also FALSE.

COVID-19 vaccination merely teaches your immune system to identify the real SARS-CoV-2 virus, and learn how to make antibodies against it.

It is IMPOSSIBLE for any COVID-19 vaccine to prevent you from acquiring immunity against other viruses.

Fact #4 : Quote Is In Page 23, Not Page 24

The viral message wrongly asks you to read Page 24 of the COVID-19 Vaccine Surveillance Report (Week 42).

Based on how often the message is being shared, it looks like that NO ONE actually opened the report to read Page 24.

Instead, they all forwarded the viral message, WITHOUT READING and certainly, without first verifying the information.

Fact #5 : Roche N Assay Only Detects Post-Infection Antibodies

In Page 19 of the surveillance report, it is clearly stated that Roche N (nucleoprotein) assay only detects “post-infection antibodies“.

That’s because COVID-19 vaccines used in the UK only produce S (spike) antibodies, so any N antibodies detected would be from actual COVID-19 infections.

Hence, it’s being used to determine how many people who have antibodies from a COVID-19 infection, instead of a COVID-19 vaccine.

Fact #6 : Report Was Gauging Population Exposure To COVID-19

The quote actually refers to the prevalence of S (spike) and N (nucleoprotein) antibodies in UK blood donors, as a way to gauge the population’s exposure to COVID-19. It does not refer to the person’s immunity to COVID-19.

The full section (quote in bold) clearly refers to the surveillance of blood donors, not their immunity to COVID-19.

Seropositivity estimates for S antibody in blood donors are likely to be higher than would be expected in the general population and this probably reflects the fact that donors are more likely to be vaccinated.

Seropositivity estimates for N antibody will underestimate the proportion of the population previously infected due to:

(i) blood donors are potentially less likely to be exposed to natural infection than age matched individuals in the general population

(ii) waning of the N antibody response over time and

(iii) recent observations from UK Health Security Agency (UKHSA) surveillance data that N antibody levels appear to be lower in individuals who acquire infection following 2 doses of vaccination.

Fact #7 : N Antibody Levels Should Be Lower In Vaccinated People

Fully-vaccinated people produce S antibodies that attach to the SARS-CoV-2 virus, physically blocking it from attaching to our cells and infecting them.

N antibody levels are naturally expected to be lower in vaccinated people, as the S antibodies from the vaccine reduce the viral load and the need for the immune system to produce N antibodies.

The viral message claims that this is a sign of your immune system failing. That’s utter nonsense.

This is actually evidence that the S antibodies produced by the COVID-19 vaccine have effectively reduced infections by the coronavirus.

Fact #8 : N Antibodies Do Not Block Attachment

Most COVID-19 vaccines target the S (Spike) protein, because that is what the SARS-CoV-2 virus uses to infect our cells.

The S antibodies they produce attach to the virus’ spike protein, physically blocking it from attaching to our cells, therefore blocking the infection.

N antibodies, on the other hand, will attach to the nucleocapsid (protein shell) of the coronavirus, which may not block attachment since the spike proteins remain exposed.

That is why inactivated virus vaccines like the Sinovac CoronaVac vaccine are far less effective than vaccines that target the spike protein, like the AstraZeneca or Pfizer vaccines.

Fact #9 : Spike Mutations Will Evade Natural Immunity Too

The claim that natural immunity is superior to COVID-19 vaccination is nonsense.

Any spike mutations that evade vaccine-produced antibodies will also evade antibodies produced through COVID-19 infection in unvaccinated people. That’s because our immune system produces antibodies according to what the virus presents to the body.

For example, if you are unvaccinated and get a natural infection by the Delta variant, your body will produce S and N antibodies specific to the Delta variant.

If you then get infected by the Omicron variant, the Delta-specific S and N antibodies already produced by your body may not attach to the Omicron variant virus as well as it would to a Delta variant virus.

Fact #10 : Unvaccinated Will NOT Get Lasting Protection From Infection

Lest it is not clear enough – a natural COVID-19 infection will NOT necessarily impart lasting protection against future COVID-19 infections. Neither will it protect you against new variants like Omicron and beyond.

Unvaccinated people who had already survived a COVID-19 infection can get reinfected. Some have even died after being reinfected with COVID-19.

  • 1%-10% of people infected with COVID-19 do NOT develop detectable neutralising antibodies.
  • Individuals with mild / asymptomatic infections tend to have lower antibody levels.
  • Some studies have shown that waning of antibody levels occurs within several months after infection.

It is therefore folly to rely on “natural” COVID-19 infections to obtain protection. That is like going to war with an alien species without going to boot camp first.

COVID-19 vaccination is a self defence class for our immune system. It prepares our immune system for battle, so get vaccinated for the best outcome against COVID-19!
