TRAVEL INDUSTRY

The travel industry will have to "roll with the punches" as government requirements continue to evolve with the pandemic, Todd Handcock, President of Asia Pacific &Global Board Member Collinson International, told CNBC this week.

"The key thing is that the industry will remain in flux for the foreseeable future," he said, noting that testing and vaccinations will continue to be part of the process of travel for 2022 and possibly 2023.

Asked if verification of tests and vaccination statuses could be simplified for travel, Handcock said the goal is to have a digital, interoperable system that can be used globally. "We're still a long ways away" from that.

Raising vaccination rates around the world would also be good for anyone who travels, he said, adding that developed countries have raced ahead in offering booster shots, while much of the world hasn't been inoculated.

In addition, echoing the sentiments of experts such as those from the World Health Organization, Handcock said that COVID-19 variants will emerge as long as there are large, unvaccinated populations.

VACCINE EFFECTS

A new scientific study showed that vaccination can cause changes to the timing of menstruation, but the effects are temporary, more akin to a sore arm than a serious adverse event, reported the National Public Radio (NPR).

"I think it's reassuring and also validating," Alison Edelman, leader of the study and professor of obstetrics and gynecology at Oregon Health &Science University in Portland, Oregon, was quoted as saying.

The work appeared Thursday in the American Journal of Obstetrics and Gynecology. Despite the effects, Edelman and other experts stressed that individuals should get vaccinated, because the risks from COVID-19 remain high.

Clinical trials for COVID-19 vaccines looked for side-effects like headaches or fever, but when it came to reproductive health, the main focus was on pregnancy, not menstruation.

"The menstrual cycle is like the stepsister that gets ignored," Edelman said. "It's considered unimportant in the grand scheme of things, but it actually really is important to people day-to-day."
