Why COVID-19 Vaccine Efficacy Does NOT Matter!

Spread the love

The public is obsessed over COVID-19 vaccine efficacy rates, but the truth is – they don’t actually matter!

Find out what COVID-19 vaccine efficacy really mean, and why they don’t matter.


Vaccine Efficacy vs Effectiveness : What’s The Difference?

Vaccine efficacy is the reduction in disease (in percentage) that occurs in a vaccinated group under optimal conditions, compared to an unvaccinated group.

Do not confuse it with vaccine effectiveness, which is the real world ability of the vaccine to prevent the disease.

Vaccine effectiveness may be lowered by underlying chronic conditions, medication, age, and even how the vaccine is stored and administered.

Why COVID-19 Vaccine Efficacy Does NOT Matter!


Vaccine Efficacy : What Does It Mean?

The Pfizer and Moderna mRNA vaccines passed their Phase 3 trials with 94% to 95% efficacy rates, but what does that mean?

The efficacy rate is actually a calculation of the vaccine’s ability to prevent symptomatic COVID-19 infection, based on the clinical trial data and the COVID-19 attack rate.

The public often miss the importance of the COVID-19 attack rate, and therefore misunderstand the vaccine efficacy rate.

For example, in a trial involving 100,000 vaccinated participants and a COVID-19 attack rate of 1%, here is the difference between perception and reality :

Efficacy RatePerceptionReality
95%5000 infections50 infections
90%10,000 infections100 infections
85%15,000 infections150 infections
80%20,000 infections200 infections
75%25,000 infections250 infections

While the public look at a 75% efficacy rate and think that it means 25% of those vaccinated will still get infected, the truth is only 0.25% of those vaccinated will get infected, with a 1% attack rate.

This is why we should leave the science to the professionals, and not pretend that a few hours of looking up Google will replace years of actual study and experience.

Vaccine Efficacy Blinds Us To What Matters More!

The public is obsessed over COVID-19 vaccine efficacy rates, but the truth is – they don’t actually matter!

To be clear, COVID-19 vaccine efficacy is important, just not to us. That’s because it refers to the vaccine’s ability to protect against any symptomatic COVID-19 infection.

Regulatory bodies around the world set a minimum threshold of 50% efficacy against symptomatic infection for the approval of any COVID-19 vaccine.

However, that has confused many people into thinking that the authorities are taking shortcuts in giving us vaccines that barely work.

Come on – 50% efficacy? That’s like rolling the dice at the roulette table, right? That’s really NOT the case.

We prepared this table to show you how misleading efficacy rates are.

Forget Efficacy, Focus On Severe Disease + Death!

The truth is all approved vaccines will protect you against severe disease, and prevent you from dying from COVID-19.

It would be really nice if you get a vaccine that protects you against even mild COVID-19, but not getting killed by it sounds pretty awesome to us!

Ultimately, whether we decide to get vaccinated should NOT depend on the vaccine’s efficacy, but its ability to protect us against severe disease or death.

Irrespective of what vaccine you receive, the table shows that they will protect you against DEATH and greatly protect you against severe COVID-19 disease.

So, instead of arguing over which COVID-19 vaccine is better, and demanding the right to choose, just take the FIRST vaccine you can get, and COMPLETE it!

Think of the COVID-19 vaccine as body armour. When you are in a firefight, do you really want to wait until you find the body armour you prefer, or would you rather wear the first one you come across?

No matter how “pathetic” or “ratty” the first body armour you find “looks” to you, it will definitely protect you better than a plain t-shirt, won’t it?

So take the first COVID-19 vaccine you are offered, and complete it. It will protect you against death and severe COVID-19 disease!
