In the months after she first got sick with COVID-19 in March 2020, Jennifer Minhas developed a cluster of mysterious symptoms.

"I had profound fatigue," she says, along with brain fog, headaches and a rapid heartbeat, especially when she changed positions from lying down to standing up.

In the early months of the vaccination campaign, Internet access was essential to the search for a vaccination appointment.

But given that more than 14 million people in the U.S. lack reliable access to high speed Internet, technology has been a barrier for some Americans.

The Centers for Disease Control and Prevention says people who are fully vaccinated do not need to wear a mask when they're outdoors unless they're in a crowd, such as attending a live performance, sporting event or parade. People are considered fully vaccinated two weeks after receiving the second dose of the Pfizer or Moderna vaccines, or two weeks after the single dose of the Johnson & Johnson shot.

A political debate has erupted over the idea of requiring proof of COVID-19 vaccination for entry into certain settings. While politicians argue over equity and privacy concerns, some businesses and institutions are moving ahead and developing apps for people to prove their status easily and securely.

When students return to Cornell University for the fall semester, for example, they'll be required to be vaccinated with exemptions for medical or religious reasons.

The Centers for Disease Control and Prevention has updated its guidance for schools. On Friday, the agency announced it "now recommends that, with universal masking, students should maintain a distance of at least 3 feet in classroom settings."

If you long to see loved ones or dip your toes in the sand, you're not alone.

It's been over a year since the pandemic locked down most of the U.S., and despite guidance from the Centers for Disease Control and Prevention to avoid nonessential travel, more Americans are now on the go — booking flights and planning vacations.

The Centers for Disease Control and Prevention has issued new guidance for vaccinated people, giving the green light to resume some pre-pandemic activities and relax precautions that have been in place.

COVID-19 vaccines are akin to liquid gold these days. As more people become eligible, the demand continues to outstrip current supply. And while states aim to manage their weekly allotments of the Pfizer and Moderna vaccines to ensure there are enough shots for second doses, there are scattered reports of snafus and postponed appointments.

As coronavirus cases surge around the country, President-elect Joe Biden says voters have given him a mandate to take action.

"Daily cases are skyrocketing," Biden said in remarks Friday evening in Wilmington, Del., as the nation waited for the election to be called. "I want everyone — everyone — to know on Day 1, we're going to put our plan to control this virus into action."

As Election Day nears, the pandemic looms large. Amid a surge in new cases, the coronavirus has changed the way we live, work and — perhaps — how some Americans will vote.

As President Trump makes the case that his leadership has saved lives in the pandemic and ushered in record-fast vaccine and therapeutics development, Joe Biden has described Trump's handling of COVID-19 as "totally irresponsible" and points to American's health as the nation's top domestic issue.

Pfizer announced this week that it has received FDA approval to enroll children as young as 12 years old in its COVID-19 vaccine trial. The expansion is aimed at understanding whether the vaccine would be safe and effective for adolescents.

Until now, children under 16 have not been included in any of the COVID-19 vaccine trials in the U.S., and the average age of participants has skewed much older.

As we get closer to a COVID-19 vaccine, it's exciting to imagine a day when the virus is gone. But a vaccine will not be a magic bullet. In fact, it may be only about 50% effective.

Dr. Anthony Fauci, chief of the National Institute of Health and Infectious Disease, has tried to set realistic expectations when discussing the importance of a vaccine. "We don't know yet what the efficacy might be. We don't know if it will be 50% or 60%," Fauci said during a Brown University event in August.

As students return to the campus of University of Illinois at Urbana-Champaign this month, they will be tested for COVID-19. And, then they'll be tested, again.

"We are requiring testing two times per week for access to campus facilities. This is for students, faculty, and staff," explains Rebecca Lee Smith, an associate professor of epidemiology.

As schools across the country grapple with bringing kids back into the classroom, parents — and teachers — are worried about safety. We asked pediatricians, infectious disease specialists and education experts for help evaluating school district plans.

What we learned: There's no such thing as zero risk, but certain practices can lower the risk of an outbreak at school and keep kids, teachers and families safer.

Parents, teachers and students across the country are gearing up for the new school year. But what school will look like is still a mystery.
