Vaccines are proven to be an effective tool to slow down the spread of the Coronavirus around the world. The difference in popularity for each COVID variant requires a different spread of people vaccinated in that area. In order to limit the transmissibility
of COVID-19, scientists recommend that the vaccine coverage should be around 60%. Generally, the notion of a widely vaccinated population accounts for the minority groups of people who are unvaccinated. Due to this, vaccination itself is prevalently
regarded as a decision between personal benefit and societal loss, which necessarily involves in the discussion of justice and fairness.
Percentage of Vaccine Doses Administered by County (Elders over 65)
Due to the fact that older age groups are among the weaker population in combatting against the virus, particularly those who have chronic condition, an important aspect to control the spread of the virus is figuring out a way to disperse effective
vaccines to these vulnerable age groups. From the graph, we can clearly identify the ratio of elderly population who received the first dosage of vaccine in major cities around Taiwan. Cities that are under 60% of the expected vaccination
coverage are labeled in red, and those who are higher than 60% are labeled in blue.
A good indicator of the current COVID-19 trends is the average number of confirmed cases published by the official CDC of Taiwan. Due to various reasons, such as automatic calibration of information conducted by the government to manipulate perceptions
of the current trends, it is proven by multiple agencies around the world that a 7-day average number of confirmed cases is the optimal data to analyze the current trends, as it is least likely to be tampered by various factors.
From the data provided by the government, we’ve conducted analysis using a human pyramid that reflects the daily confirmed cases and categorizing them based on gender and age. Something that is worth mentioning is the idea that the number on the
human pyramid is number of confirmed cases, rather than a percentage. Ever since May of 2021, it is clear that the majority of confirmed cases lies underneath the older age groups, and as local cases decrease, there was less of a relationship
between gender and age.
Development Trend of Case Fatality Rate for Different Age Groups
For different age groups, the risk of mortality due to the coronavirus varies. Due to the fact that Elders with chronic conditions have the highest chance of mortality, we have separated different age groups and their respected mortality rates
and constructed them into a visible trend. From the diagram, the mortality rate of age 60 and above in Taiwan is clearly higher than the average mortality rate observed. Specifically, for patients aged 70 or above, nearly 20% to 25% of the
