In the province of Buenos Aires, the most populated in Argentina, 25% of those over 18 years old had not signed up to be vaccinated against covid-19 until a month ago, according to official figures.
Now that indicator has dropped to 10%, which is equivalent to 2 million people.
The provincial government organized a house-to-house operation for them.
We accompany the "hunters" in this mission that goes through businesses, squares and homes to find those who have not yet received the vaccine.
