The Pfizer booster shot is now available to eligible populations at various CVS locations, according to a release from CVS.

It’s becoming easier and easier to find an available COVID-19 vaccine, which for many, comes as a relief following a tough past year or so.

As distribution and administered shots continue, here are some key questions and answers surrounding the Pfizer vaccine. How long until a second dose is proven effective? A study in the New England Journal of Medicine found that after a second dose of the Pfizer vaccine, efficiency rose to 95% after seven or more days. Should you still get a second shot if you had side effects from the first shot? Only avoid a second shot if it’s recommended by a vaccine provider or doctor.

But for those who are waiting to get a COVID-19 vaccine, when is a good time to take that trip to paradise? Millions of people have been vaccinated in the United States, but there is still a long way to go until a majority of the country is fully vaccinated. The CDC still recommends that travel should only be something you do if it’s absolutely necessary, especially if you are not fully vaccinated. Now the question remains: What should you do once you are fully vaccinated? If you’re fully vaccinated and decide to travel, the CDC recommends you take all of the same steps to protect yourself from COVID-19 that an unvaccinated person would.
