While shots in the U.S. are initially going only to those who meet specific criteria, there are various plans throughout different countries to ensure that citizens -- particularly those at higher risk for health complications -- are safely administered the vaccine.
Among those that have received the vaccination are a few stars. Here's a look at the public figures -- from movie and TV stars to British royalty -- who have begun their vaccination process.
Jonathan Van Ness
The reality star, who is HIV positive, met the criteria of being able to receive the first dose and urged others to "please check your states guidelines to see if you’re eligible and get vaccinated against covid-19!"
In regards to side effects, Van Ness stated, "This was my first shot and other than minor soreness in my arm had no side effects and will get my second shot in a few weeks."
"I cannot tell you how emotional I was and still am right now," said Kloots, 38, on Instagram. "I had [son] Elvis beside me and Live Your Life playing in the car. THANK YOU to the National Guard that was here today volunteering since 5:30am administering the Pfizer vaccine to willing arms."
"I have been terrified since Nick has passed, as a single mother, of getting this virus and now I am one step closer to safety," Kloots continued.
Heavy metal legend and former Black Sabbath vocalist Ozzy Osbourne, 72, received the first dose of the COVID-19 vaccine in mid-February.
Appearing on the "Loose Women" talk show alongside wife Sharon, 68, Ozzy opened up about receiving the shot and revealed how painful it was initially.
"It felt like I was being stabbed," he said laughingly. "My arm was sore yesterday, but I'm glad I got it, you know?"
"As soon as I got it, I felt relieved," he added.
Prince Charles and Camilla, Duchess of Cornwall
The Prince of Wales, 72, and the Duchess of Cornwall, 73, have received the first dose of the COVID-19 vaccine, Clarence House confirmed to People magazine in early February.
The members of the royal family are within the age range of people who the U.K. is currently vaccinating. Citizens over the age of 80 and health workers are also in the process of getting vaccinated.
The news comes nearly a year after the Prince of Wales tested positive for the coronavirus, though he only experienced "mild symptoms."
"THANK YOU http://PublicHealth.LACounty.Gov CHA Hollywood Presbyterian Medical Center, and my dear friend, Dr. Maria Teresa Ochoa. Light at the end of the tunnel (after one year of self imposed quarantine)," the Oscar-winner wrote on Twitter.
The actor celebrated his 83rd birthday on Dec. 31. During the pandemic, he's been spending the pandemic entertaining his cat by playing the piano.
"Niblo is making sure I stay healthy and demands I entertain him in exchange… cats," Sir Anthony wrote on social media.
"Analyze This" actor Billy Crystal, 72, received the first dose of the COVID-19 vaccine in late January, which he announced on "The Late Show with Stephen Colbert."
"I got the injection and a free scarf," Crystal jokingly recalled. "I was glad to get this first step toward hugging my kids and my grandchildren again — and I do have a pre-existing, underlying condition, which is terror. So, that was good that I got that [vaccine]."
"The Terminator" actor and former Republican governor of California announced on Twitter in January that he'd received a vaccination shot.
"Today was a good day. I have never been happier to wait in a line," Schwarzenegger wrote alongside a video on himself getting an injection. "If you’re eligible, join me and sign up to get your vaccine."
In reference to a famous line from "The Terminator," he added: "Come with me if you want to live!"
The 73-year-old actor said in a follow-up tweet that Los Angeles Mayor Eric Garcetti checked him in at a vaccination site at Dodger Stadium, which he called "a crazy surprise."
The legendary comic, 75, revealed on Twitter in January that he'd also received his vaccination, in part because of his age.
"Good news/Bad news. Good news: I just got vaccinated! Bad news: I got it because I’m 75. Ha!" he said on Sunday. "The operation in NYC was smooth as silk (sorry about the cliché @BCDreyer!) and hosted to perfection by the US Army and National Guard. Thank you all, and thank you science."
When a fan asked Martin how he signed up for it, the "Planes, Trains, and Automobiles" star said he signed up online.
"I signed up ON line through an NYC dot gov website (sorry I don’t have the exact site), and waited IN line at the Javits Center," he recalled and joked he was having no "fide resects."
The 87-year-old country star's vaccination was announced on Facebook by Family Hospital Systems.
It shared a photo of Nelson giving a thumbs up while wearing a face mask.
"Getting your COVID vaccine is Willie cool!" the organization joked in the caption. "Thank you Willie Nelson for helping Family Hospital Systems slow the spread of COVID-19."
Another icon of the country music industry, 88-year-old Lynn announced on Instagram that she's gotten her shot as well.
The "Coal Miner's Daughter" singer shared a pair of photos: one of herself smiling and another close-up of a sticker reading "I got my COVID-19 vaccine!"
"Well, I bundled up and Peggy Jean and I rolled out of Hurricane Mills so I could get this vaccine," she said in the caption. "I’m sure glad to get it and am sure ready to put Covid in the rear view mirror! And I enjoyed the mom daughter time, too!"
A similar message made it to Twitter, featuring the photo of the sticker.
"I did it," Lynn captioned the pic. "You can, too!"
Dench, 86, announced her vaccination as well.
"I have [had the coronavirus vaccine]. I had one a week ago so I think my next is something like 11 weeks' time, that's a great start!" she told BBC in January, per the Daily Mail.
She also said that she felt "joy" and "relief" at having been administered the vaccine, as she can now pick up where she left off when it comes to acting.
At 94 years old, it stands to reason that the classic crooner would receive a dose of the vaccine early in the rollout.
Bennett took to Twitter on Jan. 13 to share that he'd received an injection.
"I received the first dose of the Covid 19 vaccination this week and am doing fine and encourage you to do the same!" he said alongside a photo of himself smiling.
On Jan. 11, the home goods mogul, 79, shared a video of herself prepping to be injected with the vaccine.
"I was vaccinated today in a designated vaccine pod near the Martha Stewart Center for Living at Mount Sinai Downtown I am so proud of and grateful to the doctors, nurses and medical staff who are wading through the red tape and confusion of the distribution of these very important vaccines," she captioned the post, in part.
The star said she was "excited to have received" the vaccine, and claimed that Mount Sinai had received 10,000 applications for administration.
"Here’s to the advancement of science and a heartfelt thanks to those working on the vaccines. We are all hoping for an end to this pandemic," she concluded. "To allay your concerns that I jumped the line know that I am in the approved age group for this batch of vaccines and I waited in line with others."
The 87-year-old "Dynasty" icon said on Instragram she was "delighted" to have received her first dose in January. Her post included a photo of herself with a medical professional administering the shot.
She later spoke to "Good Morning Britain" about the procedure.
"I just really want to tell anybody who is worried about it: There is nothing to worry about," she urged. "It was the easiest thing, it was just like a little scratch and there was no pain at all. I had no after-effects and I felt absolutely fine.
In fact, Collins said that she "went home and I had a drink, even."
Queen Elizabeth II and Prince Philip
Britain's highest royals were also able to obtain vaccines.
"The Queen and The Duke of Edinburgh have today received Covid-19 vaccinations," the announcement states.
A royal source confirmed the vaccinations were administered "by a household doctor at Windsor Castle," where the royal pair have been living amid the global health crisis.
Queen Margrethe II
More royals were able to obtain treatment as well.
Denmark's Queen Margrethe II, 80, received her vaccination not long after the rollout began.
"Her Majesty The Queen has been vaccinated against COVID-19 today," the Amalienborg Palace announced on its website on New Year’s Day.
"The Queen will receive a follow-up vaccination in approximately three weeks," the statement revealed.
Actor, writer, producer and director Tyler Perry is among those to have received the treatment and will discuss his vaccination experience on the BET program, "Covid-19 Vaccine and the Black Community: A Tyler Perry Special."
"I was skeptical because if you look at our history in this country with the Tuskegee experiment, Henriette Lacks, things like that, it raises flags for us as African-American people," Perry said on "CBS This Morning."
Grady Health System suggested that administering the vaccine to the 51-year-old star would help send a message of safety to the public, and Perry ultimately agreed.
"I’m not taking this vaccine because I want you to take it, I want to give you the information so you make your own choices," he added. "I think that’s what it’s about, education and information."
Movie star and humanitarian Sean Penn has also received the treatment.
The 60-year-old actor star shared a photo of himself getting vaccinated on Twitter.
"I’m a lucky man. Lucky to work alongside the @LAFD & our great frontline @CoreResponse staff, our partners at Carbon Health, USC, & Curative Lab," he wrote in the post. "We test & vaccinate thousands per day. We need your support to get more people lucky. Text CORE to 707070 to donate."
"It's Not Unusual" crooner Tom Jones revealed that he's been injected during an appearance on the 'Jools Holland's Annual Hootenanny' show, per Daily Mail.
"I've had my jab already," he said. "That's one good thing about being 80, you're first in line for the jab."
The shot didn't seem to bother him at all.
"It was fine, it was like getting the flu jab," said the singer.
Broadway icon Joel Grey received a shot in January.
The 88-year-old star said that he "got the vaccine because I want to be safe. We've lost so many people to COVID. I've lost a few friends. It's heartbreaking. Frightening. Like boxing with the enemy. What's been helping me is a solid belief that there is an end. I want to live. I love life," according to People.
Another British icon has been vaccinated.
Patrick Stewart, 80, announced on Instagram in January that he'd received an injection by sharing a video from the drive-through site.
"How do we say thank you to the health workers and scientists for their sacrifice and service? Receive the vaccine as soon as one can to lessen their load and keep wearing a mask to protect fellow citizens," he captioned the post. "In my 80th year, I am grateful and hopeful for better days ahead."
"Orange Is the New Black" star Kate Mulgrew also shared online that she'd been vaccinated.
"Got my Covid-19 vaccine in the wee hours of Monday morning! Consider this an order from your Captain - continue to mask up & register to receive your vaccine ASAP," she wrote alongside a photo of herself showing off the bandage on her arm. "Here in the US, check the website for your individual state of residence (NY for me!) for when you can sign up."
The 65-year-old star added in a follow-up tweet: "We will beat this, but only if we all work together. Stay safe, my friends, and trust in science!"
Samuel L. Jackson
Film icon Samuel L. Jackson revealed that he'd also received a dose in January.
"At The Forum getting that 1st jab!!" the 72-year-old captioned a post on Instagram, alongside a photo of himself waiting in a parking lot of the Inglewood, Calif., arena to receive the treatment.
He added: "gogitchyoursigotmine."
The famed "Lord of the Rings" star, 81, received his vaccination in December.
"I really hope that, as more people get vaccinated, we will move further along the path back to a more normal way of life," he said, per a tweet from NHS England and NHS Improvement.
The message contained images of McKellen with a sleeve rolled up speaking with a medical professional and giving a thumbs up.
"It’s a very special day, I feel euphoric. I would have no hesitation in recommending it to anyone. I feel very lucky to have had the vaccine," read another tweet from the NHS quoting McKellen.
English actor Patrick Mower, 82, is also one step closer to being safe from the virus.
"Getting my COVID vaccination was incredibly simple & painless," he said in a tweet shared by Lincolnshire NHS. "I feel incredibly lucky to have had it & would like to thank all the wonderful NHS staff for making it happen."
The tweet was published on Dec. 16.
British actor and choreographer Lionel Blair announced on "Good Morning Britain" that he'd been injected as well.
"I'm feeling fine. It was the best birthday present I could have because I was 92 on December 12 and on that day they said I can have my first one, which I did, my first appointment," he told the outlet, according to Daily Mail.
During the television appearance earlier this month, the star added: "Yesterday I had my second."
