With Covid vaccinations underway, many people are wondering about travel.

The C.D.C. has recommended that Americans, even those who have been fully vaccinated, not travel yet. Case numbers have been rising in the U.S., and variants are spreading. But the reality is that many people who have received the vaccine are booking flights and trips again.

Though this summer likely won’t see travel at prepandemic levels, and many places remain closed, “bookings for almost everything are up,” Tariro Mzezewa, a Times reporter who covers travel, told me.

“Travel will go beyond the road trips of last summer,” she says. “Vaccinated people will be more comfortable being around other people.”

Expect to show some sort of proof — either of a negative test or of vaccination — when traveling. “You should be planning on showing your negative test or staying home if you don’t have one,” Tariro says.

The European Union, for example, has announced plans for the Digital Green Certificate, a so-called vaccine passport that countries can use to verify a person’s health status and allow free travel across the bloc.

The concept of a vaccine passport isn’t new: To travel to certain countries, for example, you already need inoculations against yellow fever and other diseases.

The travel industry and tech companies have been working on ways to streamline digital credentials for years, and during the pandemic some have started to repurpose that technology to show proof of vaccination. “It isn’t far off in the future,” Tariro says.

Countries are approaching travel differently. The Biden administration has said that it will leave the development of a vaccine passport in the U.S. to the private sector. At least 17 initiatives are underway, The Washington Post reported.

“Some think a coordinated, nationwide vaccine passport system could help us get back to a semblance of normal life and speed up economic recovery,” Rebecca Heilweil wrote in Recode. “But this seems unlikely.”

In Britain, Prime Minister Boris Johnson has said that vaccine passports would “definitely” play a role in the future for international travel. China has already introduced its own digital certificate, which shows a person’s vaccine and testing history, and South Korea recently announced it would issue vaccine passports to immunized citizens using a mobile app.

In Israel, a possible vision of the postpandemic future is on display. More than half of Israelis have received both vaccine shots, and cases have dropped by 90 percent. The economy has reopened with help from a “Green Pass,” an entry ticket to society.

The pass isn’t being widely used for international travel — Israel is still closed to foreign visitors out of fear of variants — but it offers access to restaurants, concerts and more. Newspapers and commercials in Israel are already advertising summer getaways for the fully vaccinated in countries that have agreed to take them, including Greece, Cyprus and Georgia, according to Isabel Kershner, a Times correspondent in Jerusalem.

Lives Lived: Bibian Mentel was a six-time Dutch snowboarding champion when she lost a leg to cancer. She was soon back on the slopes, competing against able-bodied snowboarders, and she won a gold medal seven months after her surgery. Mentel has died at 48.

The most noteworthy thing about this season of Major League Baseball, which began yesterday, is that it’s somewhat normal. After the pandemic forced major changes last year, including a 60-game schedule, the league is returning to a standard 162 games and fans are back in the stands.

Here are three things to watch for this year.

Lots of home runs. For the past five years, home runs have been flying into the stands in record numbers, and pitchers aren’t happy. To address it, the league has introduced a baseball that is less springy. Still, during spring training, batters hit it out of the park at the highest rate yet, according to The Ringer.

The best get better. The Los Angeles Dodgers have been to three of the last four World Series, and won it last year. And they seem to keep getting stronger: Over the winter they added pitcher Trevor Bauer, who won the National League Cy Young Award last year. Bill Plaschke of The Los Angeles Times has high expectations: “This season they’re going to be the best team in baseball history.”

Pandemic disruptions. The league has already postponed a game because of Covid — the opening day matchup between the Mets and the Nationals. As the season goes on, expect the virus to complicate things: Players could miss days, and teams may have to reschedule games.
