It’s been well over a year since the COVID-19 pandemic started. You’ve had to follow strict instructions, you’ve probably had all sorts of emotions, and you’ve tried to keep busy in many different ways.
Now, there’s something else to think about: vaccines.
Since they’re on everyone’s mind these days, let’s take some time to review a bit of vaccine vocabulary.
Read the passage below, then scroll down to check your understanding!
Scientists began trying to develop a COVID-19 vaccine as soon as the pandemic started. Now, a variety of vaccines are available from pharmaceutical companies. Some countries are already providing them to citizens, while others are still planning their vaccine rollouts.
The best way to eliminate the coronavirus is to vaccinate as many people as possible. If enough people get immunized, populations can achieve herd immunity, which will make everyone safer.
It’s common to be anxious about getting an injection—whether you’re afraid of having an adverse reaction or just don’t like needles, there are several reasons for vaccine hesitancy. But that doesn’t mean you shouldn’t get the vaccine if you’re able to. Coronavirus is very serious and can bring major complications, including chronic health problems.
While certain people don’t want the COVID vaccine, others believe it should be mandatory. Many countries are likely going to require that people carry vaccine passports to prove that they’re immune . . . what do you think about that?
