Dear Lauren Leatherby,

In your article, you told the readers about the relation between the delta virus and vaccines. I especially like the part where you use the animation to show the result: although the number of people who are vaccinated but still got covid19 is larger than those who aren’t, that situation only appears in the community with a higher rate of vaccination. Simply because there are many more people who are vaccinated. In a community with a low rate of vaccination, with the same number of people as the other one, the total number of patients is much higher. Furthermore, the rate of those who are hospitalized is much higher in the second community.

Though some people may not like the vaccines for fear of side effects, in the view of the countries or the world, I think people should take the vaccines. Most of the people who are vaccinated will gain protection against the virus. Even if one gets covid19, there will only be a very small possibility that it will be serious.

I think that another reason people should be vaccinated is because this virus is easy to mutate. The theory is that the virus will be like a flu more and more– which means covid19’s symptoms will be milder and easier to spread–as they mutate. But the reality is hard to predict. The delta virus is an exception. It is nearly twice as contagious as previous variants and some data shows the delta variant causes more severe illness. We don’t know when or where another variant more intense may come. We only know that this situation is more likely to happen when more people get covid19. So in order to stop this from happening, we have to be vaccinated.

Thank you for writing this article to initiate people’s concern of the effect when communities aren’t having enough vaccinations.

Sincerely, Ya Han Hsu
