This is a Scriptable iOS widget script that shows the current COVID-19 vaccination status including an estimated herd immunity date for your country of choice.

Based on marco79's great script.

To set it up for you country do the following:

1. Change the population variable to the population in your chosen country.
2. Change the herdImmunityPercentage if you want.
3. Go to the list of countries, open one, tap the Raw button, copy the URL in the address bar and set it for the dataUrl variable in the script.

Take note that the script assumes each person must get 2 vaccination doses, before they are vaccinated, as is the case with the BioNTech and Moderna vaccines.

Extended Vaccination Status.js

// Change the following constants to your country of choice
const population = 5837213;

// Go to https://github.com/owid/covid-19-data/tree/master/public/data/vaccinations/country_data and find the raw URL for your country
const dataUrl = "https://raw.githubusercontent.com/owid/covid-19-data/master/public/data/vaccinations/country_data/Denmark.csv";

Got this error :
Error on line 56:25: TypeError: null is not an object (evaluating 'result.cumsum_latest.toLocaleString')

The data got malformed and there’s a 60- minute cache in the script that held onto the malformed data. Could you try again now?

All good👌🏼
Thank you very much for sharing your great script 🙏🏼
