Answer:
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.

A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Answer:
Different vaccines are now available in various countries. In the United States, vaccines need approval from the Food and Drug Administration (FDA).
First, they need to pass through three phases of tests to prove that they are safe and effective. The last stage, phase 3, involves tens of thousands of participants.
At the time of writing, two vaccines have FDA approval for use in the U.S.:
the Pfizer-BioNTech COVID-19 vaccine
the Moderna COVID-19 vaccine
The Pfizer-BioNTech vaccine, developed in Germany, received FDA approval in the form of an emergency use authorization on December 11, 2020.
In a phase 3 trial involving more than 43,000 people, around half received a placebo and half received two doses of the vaccine, 21 days apart. The results showed that the vaccine was 95% effective at protecting against COVID-19.
The Moderna vaccine, developed in Cambridge, MA, received approval for emergency use in the U.S. on December 18. In a phase 3 trial, 30,000 volunteers received either a placebo or two doses of the vaccine, 28 days apart. The results indicated that the vaccine was 94% effective.
Other vaccines
Other vaccines that have approval for use in various countries include:
The Oxford AstraZeneca vaccine, in the United Kingdom
Coronavac, developed by Sinovac, in China
The Sputnik V vaccine, in Russia
Covaxin, developed by Bharat Biotech, in India
Meanwhile, the Novavax vaccine is currently undergoing phase 3 trials, as is Janssen’s COVID-19 vaccine. Both were developed by companies based in the U.S.
A person can keep up to date with the latest vaccine developments in the country using the Regulatory Affairs Professionals Society’s COVID-19 vaccine tracker.
Are the vaccines safe?
A vaccine needs to pass through several stages of trials before the manufacturer can apply for approval from a country’s health authority. In the U.S., the FDA gives this approval, and the Centers for Disease Control and Prevention (CDC) also work to ensure public safety.
Vaccine trials involve ever-larger numbers of people. The last stage, phase 3, includes tens of thousands of participants.
At first, the specific long-term effects of any new medical treatment, including a vaccine, are unknown. The key is to balance the potential risks of getting a vaccine that has undergone extensive testing with the known dangers of developing COVID-19.
In the short term, a person who has had a COVID-19 vaccine may experience flu-like symptoms and other side effects, including:
pain at the injection site
swelling at the injection site
fatigue
headache and muscle pain
a fever
The side effects may be worse after the second dose of the vaccine because the body’s immune response will be intensified.
The CDC encourage people to use a smartphone-based health checker called V-safe to inform the authorities about any side effects. This helps them monitor the impact of the vaccine and do ongoing work to ensure public safety.
It is essential to receive the vaccine from a licensed healthcare professional and follow every instruction, including getting a second dose. A person may get the vaccine at a local health department, hospital, clinic, or pharmacy.
Anyone with a history of allergies to vaccines or other injectable medications should tell the healthcare worker before they administer the vaccine. Anyone who has an allergic reaction after receiving the vaccine should receive emergency care. Call 911
