Dozens of coronavirus vaccines entered clinical trials during 2020, and now, a handful have been authorized forin various countries — meaning the shots can be administered to the public while their developers continue to collect data on their safety and efficacy. Should they meet all the necessary criteria, these vaccines could be fully approved in the future, and in some places, they already have been.
Here's a quick guide to the COVID-19 vaccines now in use around the world.

The vaccine developed by Pfizer and German biotechnology company BioNTech isat preventing COVID-19, a large study found. The vaccine is administered in two doses, given three weeks apart, and it must be stored at minus 94 degrees Fahrenheit (minus 70 degrees Celsius). On Dec. 11, 2020, the Pfizer-BioNTech vaccine became the first COVID-19 vaccine to be by the U.S. Food and Drug Administration (FDA).
Several other countries have also authorized the vaccine for emergency use, including the U.K., Argentina, Chile and Singapore, and the European Union followed suit on Dec. 21,. Bahrain, Canada, Saudi Arabia and Switzerland have fully approved the vaccine.
The One COVID Symptom Everyone Gets Most
A new study joins earlier research in suggesting that one symptom of coronavirus (COVID-19) is most common: Fever.In a study published Nov. 9 in The Journal of Emergency Medicine, scientists looked at nearly 12,000 people who were tested for COVID-19 at emergency rooms around New York City. In that group, the most common symptoms that accompanied a positive COVID test were: fever (74%), shortness of breath (68%), and cough (65%). Read on, and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus.
The shot uses a molecule called mRNA as its base. A molecular cousin of DNA, mRNA contains instructions to build specific proteins; in this case, the mRNA in the vaccine codes for the coronavirus spike protein, a structure that sticks off the virus's surface and is used to infect human cells. Once inside the body, the vaccine instructs human cells to build this protein, and the immune system learns to recognize and attack it.
The vaccine developed by U.S. biotech company Moderna and the National Institute of Allergy and Infectious Diseases (NIAID) also uses mRNA as its base and isat preventing COVID-19. Like the Pfizer-BioNTech vaccine, it's delivered in two doses, but the doses are given four weeks apart, rather than three. Another difference is that the Moderna vaccine can be stored at at minus 4 F (minus 20 C), rather than requiring deep-freezing like the Pfizer shots.
Dr. Fauci Just Said How to Avoid COVID This Winter
According to Dr. Fauci you can avoid COVID this winter by "Wearing masks, keeping physical distances, avoiding crowds in congregate settings."Fauci told Zuckerberg "we're not in a good place." "When you look at the numbers almost every day, either breaks a record or ties a record of cases, to have a baseline of between one and 200,000 cases a day is extraordinary. When you look at the number of deaths they have between 1,000 and 2,000, we now over 90,000 hospitalizations, the total of the outbreak is over a quarter of a million deaths, 266,000 deaths. And over 13 million cases.
The FDAfor emergency use on Dec. 18, and Israel and the European Medicines Agency, an agency of the European Union, both authorized the shots for emergency use in January, according to the Times. Canada fully approved the vaccine on Dec. 23.
The vaccineand pharmaceutical company AstraZeneca is estimated to be about 70% effective at preventing COVID-19 — that said, in clinical trials, adjusting the dose seemed to boost this efficacy.
In people given two full-size doses, spaced 28 days apart, the vaccine was about 62% effective; in those given a half-dose followed by a full dose, the vaccine was 90% effective,. However, clinical trial participants who got half-doses did so by mistake, and some scientists have questioned whether those early results are representative.
and Argentina authorized the Oxford-AstraZeneca vaccine for emergency use in late December, and India and Mexico authorized the vaccine for emergency use in January, according to the Times. The shots contain a weakened version of adenovirus, a common cold virus that naturally infects chimpanzees. Scientists modified the virus so it cannot replicate in human cells and then added genes that code for the coronavirus spike protein. Inside the body, the vaccine enters cells and delivers these spike protein genes, which the cells use to build the spike protein itself. The presence of spike proteins triggers an immune response.
The CDC Just Announced Who Should Get the COVID Vaccine First
A CDC panel voted 13-1 to recommend health care workers and residents of long term care facilities will be the first recipients of the Covid-19 vaccine when it becomes available. Wolf Blitzer discusses with CNN's Nick Watt and Dr. Sanjay Gupta.
Sinopharm (Beijing Institute of Biological Products)
Sinopharm, the state-owned China National Pharmaceutical Group, and the Beijing Institute of Biological Products developed a vaccine from an inactivated coronavirus, meaning a modified version of SARS-CoV-2 that cannot replicate. In late December,that the vaccine, called BBIBP-CorV, is more than 79% effective, according to preliminary data from late-stage clinical trials — that said, the company has not published said data.

In the summer of 2020, China gave Sinopharm authorization to vaccinate construction workers, diplomats and students with one of its two COVID-19 vaccine candidates, including BBIBP-CorV,. Nearly 1 million people had received the vaccines by November, according to the company's chairman.
The United Arab Emirates authorized BBIBP-CorV for emergency use in September and then fullyin December. Bahrain and China also fully approved the vaccine in December, and Egypt authorized it for emergency use in January 2021, . The vaccine is given in two doses spaced three weeks apart.
Fauci Issues COVID Vaccine Allergy Warning
"What the Pfizer people are saying is that if you have a history of a severe allergic reaction, you should not take this vaccine," said Fauci.In clinical trials, the vaccine was tested on 44,000 people and found to be safe and 95 percent effective. It has been authorized for emergency use and is rolling out to healthcare workers across the country. Pfizer had previously warned that people who've experienced severe allergic reactions, like anaphylaxis—a swelling of the throat that impairs breathing and can be fatal if not treated—may want to avoid it.
Sinopharm (Wuhan Institute of Biological Products)
Sinopharm's second vaccine candidate, developed by the Wuhan Institute of Biological Products, also uses an inactivated coronavirus as its base. The vaccine has been authorized for emergency use in China and the U.A.E., but little is known about its efficacy.
, in collaboration with the Beijing Institute of Biotechnology, developed a COVID-19 vaccine using a weakened adenovirus, but one that naturally infects humans, not chimpanzees. Late-stage clinical trials with the vaccine are still ongoing, and its efficacy is not yet known. The shot is given in a single dose.
In June 2020, the CanSino vaccine was given approval to be used by China's military,.
The Chinese company Sinovac Biotech developed a vaccine from an inactivated version of SARS-CoV-2. The vaccine, called CoronaVac, is given in two doses 14 days apart,. China authorized the vaccine for emergency use in July.
Estimates vary as to how well the vaccine protects against COVID-19, and an official estimate has not yet been issued. One clinical trial in Brazil suggested that the vaccine was about 78% effective in one small subgroup of patients, but across all people, the efficacy may be closer to 63%,, a Brazilian news outlet.
The Indian company Bharat Biotech, along with the Indian Council of Medical Research and the National Institute of Virology developed a vaccine from an inactivated coronavirus, called Covaxin,. The vaccine is given in two doses, spaced four weeks apart, and has been authorized for emergency use in India. It's efficacy has not been publicly reported.

Gamaleya Research Institute
The Russia Ministry of Health's Gamaleya Research Institute developed a coronavirus vaccine candidate called Sputnik V, in reference to the world's first artificial satellite, launched during the, . The vaccine contains two common cold viruses, or adenoviruses, that have been modified so they don't replicate in humans; the modified viruses also contain genes that code for the coronavirus's spike protein.
In November, Russia announced that the vaccine is more than 91.4% effective in preventing COVID-19, according to early data from clinical trials. (Full details of the trials have yet to be published in a scientific journal.)
In the same month, Russia began offering the vaccine to its citizens as part of a mass vaccination campaign, according to The New York Times. Russia had already approved the vaccine for limited use in August, when very little data from human trials was available,.
Since November, Belarus, Argentina and Serbia have also authorized the vaccine for emergency use, the Times reported.
In October 2020, Russia granted "regulatory approval" to a second vaccine, one developed by the Vector Institute, a Russian biological research center,. The vaccine contains coronavirus peptides, which are small portions of proteins found in the virus. Like Sputnik V, the vaccine earned approval in Russia before large-scale clinical trials had been conducted. As of now, its efficacy is still unknown.
