Why Discriminate Against Unvaccinated?

21 October 2021

Nowadays,   it is common for countries to restrict the movement of the unvaccinated.  Some do not allow unvaccinated to enter PUBs,  some,  to enter malls and public places. This has made many people very unhappy.   Some even take the matter to the street,  protesting against the Government for unfairness and discrimination, and for disrupting their daily and family life. This article will try to illustrate why there is such a rule using the available data provided by MOH of Singapore.

Singapore's New Covid Rule

Singapore changed its Covid rule on 9 October 2021.  The new rule allows only groups of up to 2 fully vaccinated persons to dine in at hawker centres and coffee shops, and to enter shopping malls and attractions.  The Authority did not elaborate much on the reasons for such a move when they first announced the new rule. 

 

Possible & Likely Reasons for such Move

The following are the possible and likely reasons:

1.  The number of those severely ill patients requiring oxygen support and ICU has risen exponentially;  most of these patients are unvaccinated and many of them are seniors;

3.  The existing and available medical facilities have almost been exhausted;  it is expensive and wasteful to increase the facilities unless it cannot be avoided.   

The Explanatory Charts

MOH has published several data and charts as shown in the appendix.   Among them,  only the following chart could explain and back up the reasons.  This chart shows that the Not-Fully-Vaccinated (NFV) are using up more than 50% of oxygen and ICU facilities at the present date.  But the number of unvaccinated at present is less than 10% of the population if we were to exclude those below 12 years old.

The following charts expanded from the MOH's data show the attack rate of those severely ill patients recently admitted to the hospital.      The rate is worked out based on this formula

The working of such a formula is explained in this wiki.

The chart shows  the % of people who become severely ill after  having exposed to Covid-19. 

1)  Attack Rate for Severely ill Vaccinated/Not-Fully-Vaccinated (NFV) Patients

2)  Number of Deceased

One can readily see from the above 2 charts that the attack rate of the unvaccinated and the number of death have risen significantly in recent weeks.  Most of the death are Not-Fully-Vaccinated patients (NFV).    They, unfortunately, loaded up the existing and available medical facilities.   This must-have prompted the Singapore Government to introduce the new Covid Rule as the first step to restrict the movements of the NFV.
