That’s a screenshot from a pseudoscientific conspiracy website with questions over its true provenance and funding:

This is not a reputable site - it claims that masks are not only ineffective, but can increase the risk of COVID. This has been debunked.
Some people can’t get the vaccine for medical reasons. That’s why it is important that others do, so that those people are protected.
Vaccines are not just about protecting ourselves, they are about providing protection on a societal level - they slow the spread of the virus, the slow the risk of mutation the greater the number of people who are vaccinated, and on average they reduced the severity of symptoms for those who still catch a current strain of COVID even if fully vaccinated.
There is a lot of vaccine misinformation swimming around and it’s easy to get sucked in.
As one epidemiologist recently put it, by mixing large numbers of vaccinated people without any care or caution with unvaccinated people, we are creating a perfect test ground for vaccine mutation.
