We know what happens when you get the COVID-19 vaccine, but what about the people who don't take it? What could lie ahead in their future?

For all those who have already been vaccinated, or will be getting the COVID-19 shot soon, we know from the science that you'll gain nearly full protection from the virus.

However, there are those who will choose not to get vaccinated, and Dr. John Swatzberg from UC Berkeley knows exactly what will happen. According to newstimes.com, here's what he had to say:

"We know what will happen to them. With a virus that is as contagious as this one and becoming more contagious due to variants, people who decide not to get vaccinated are likely over time to get infected. Ultimately, the people who choose to not get vaccinated will contribute to herd immunity by the fact that they got infected. From a societal standpoint, people who skip the vaccine could compromise the safety of others."

Herd immunity is a term we're hearing a lot of lately because it makes it difficult for the virus to spread when enough people are protected either from the vaccine or because they already have the antibodies from having COVID-19.

We need to get to herd immunity to protect those people who can’t get vaccinated. They’re delaying the safety for all of us. I hear everyone saying deciding to get vaccinated is an individual choice, but the calculus in that choice is twofold — one is to vaccinate yourself and the other is protect others. I think we have a responsibility to protect our communities.

You may be one of those who's not sure about the vaccine due to a number of reasons, but there are some rumblings including here in Connecticut where going to a concert, taking a flight on any of the major airlines, or even going to a sporting event may not be possible for those who don't have proof of being vaccinated with a 'COVID Passport Card'.

Here's what Connecticut Governor Ned Lamont had to say on NPR recently about the Coronavirus Passport:

These are the ways that people are beginning to think about the nature of a vaccination passport, or vaccination authentication, we've got to make sure we do it respecting civil liberties and people's privacy, but I think you are going to see a lot of innovative ideas coming out of it.

It will give a lot more people an incentive to get vaccinated. If you are a white male Republican and you feel a little grumpy about getting vaccinated, maybe NASCAR says you've got to be vaccinated to come in and see a race.

There are also other reasons people may want to consider getting the vaccine. According to fox19.com Rutgers University says it will require that all students be vaccinated for the coronavirus before arriving for classes in the fall. The university said in statement Thursday that assurances from the federal government of vaccine supply for all Americans prompted them to make the decision.

There's also the doughnut chain Krispy Kreme who's offering free doughnut's to anyone who got the vaccine, however to be fair, there's also some offers popping up from business owners who understand there are people that are reluctant to get the vaccine. One in particular is a New Jersey gym who is offering a "free membership" to anyone who doesn't get the vaccine.

Despite the massive push to get vaccinated, there are people who want the vaccine but due to limited supply, can't get it. But as supplies increase, the narrative will shift to those who can get it, but refuse it.

Those numbers have shifted dramatically in the last few months. According to national reserch more people say they will take the vaccine then people did back in January when the vaccine was first rolled out to the public.

This debate may continue through the next few months, but right now there are still no plans to make the vaccine mandatory. Dr. Paul Offit who's a professor at the University of Pennsylvania, and coinventor of the rotavirus vaccine said it may take a little more time to get those skeptical vaccinated.

The weather is getting better and more people are getting vaccinated. We are going to reach a time in the summer when we’re going to feel good, then by fall or even by next winter when it gets cold and everyone goes back inside, you’ll see if you’ve vaccinated enough of the population to stop the spread.
