Coronavirus Vaccine – Facts, Research, FAQs

To end this pandemic, we need to get vaccinated. A substantial part of the world needs to get protected from the virus. The different secure strategy to accomplish this is with a vaccine. Vaccines are the techniques that served humanity from various infectious conditions in the past.

In less than 12 months following the COVID-19 pandemic, several study organisations took up the charge of taking vaccines that shield against SARS-CoV-2, the virus that causes COVID-19.

The Coronavirus Vaccine Testing Process

Preclinical Testing: Scientists examine a new vaccine on cells and later test it on animals, like mice or monkeys to check if it offers an immune response.

Phase 1 Safety Trials: Scientists test the vaccine on a small group of volunteers for safety, dosage and to verify that it safeguards and increases immunity.

Phase 2 Expanded Trials: Scientists test the vaccine on hundreds of people divided into groups like children and the elderly, to check if the vaccine works and affects differently in them.

Phase 2 Efficacy Trials: Scientists test the vaccine on thousands of people and anticipate to check if people become infected, corresponded with volunteers who took a placebo vaccine. These examinations can decide if the vaccine shields us against the coronavirus, calculating what’s known as the efficacy rate. Phase 3 tests are also good enough to reveal evidence of comparatively rare side effects.

Early or Limited Approval: Various countries have plans for giving emergency permissions for vaccines, based on preliminary test proofs that these vaccines are safe and effective.

Approval: Governors evaluate the entire trial results and plans for a vaccine’s manufacturing, and choose whether or not to provide it full approval.

Combine phases: One method to speed up vaccine development is to combine phases.

Paused or Abandoned: If researchers witness troubling signs in volunteers, they can pause the trial. Following an investigation, the trial may continue or be abandoned.

COVID-19 vaccine Safety

Beyond 380 million doses of the COVID-19 vaccine have been produced in the United States from December 14, 2020, through September 13, 2021.

COVID-19 vaccines are secure and effective. COVID-19 vaccines were estimated in tens of thousands of partners in clinical tests. The vaccines met the Food and Drug Administration’s (FDA) severe scientific criteria for safety, effectiveness, and manufacturing quality required to recommend approval or support of a vaccine.

“Millions of People Have Safely Received a COVID-19 Vaccine”

Millions of people in the United States have got COVID-19 vaccines because they were approved for emergency use by FDA. These vaccines have experienced and will continue to undergo the most intensive safety screening in the U.S.

Now the difficulty is to get these vaccines available to people throughout the globe.

Results are promising

Results from vaccine safety monitoring forces are convincing. There are negative side effects. Others have listed typical side effects following COVID-19 vaccination, like

“42.6% of the world population has taken at least one dose of a COVID-19 vaccine.

5.82 billion doses have been administered globally.”

Chances of Severe Safety Problems

There are only two serious types of health problems after vaccination that are reported by the monitored system. These are anaphylaxis and thrombosis with thrombocytopenia syndrome (TTS) after vaccination.


A tiny number of people have reported having a severe allergic reaction (called “anaphylaxis”) after vaccination, which is rare. Anaphylaxis can trigger after any vaccination. If anaphylaxis is triggered, vaccination providers have drugs available to efficiently and immediately manage the reaction. After the vaccine shot you will be asked to stay for 15–30 minutes so you can be observed for allergic reaction and need immediate treatment.

Thrombosis with Thrombocytopenia Syndrome (TTS)

After taking COVID-19 Vaccine, there is a rare risk of blood clots with low platelets that is thrombosis with thrombocytopenia syndrome, or TTS.

This situation is rare, with the rate of 7 per 1 million vaccinated women between 18 and 49 years old. For women 50 years and older and men of all ages, this event is even rarer.

Frequently Asked Questions about COVID-19 Vaccination

Are COVID-19 vaccines Safe?

Although COVID-19 vaccines are developed rapidly, it has passed all the vaccine testing trials for safety and effectiveness so that it can be administered to people.

Can I get vaccinated if I have COVID-19?

No. People with COVID-19 should wait to be vaccinated until they have recovered.

COVID-19 vaccines ingredients?

Vaccine ingredients change from one manufacturer to another. No vaccines contain eggs, gelatin, latex, etc. Also are free from elements like iron, nickel, cobalt, lithium, microelectronics, electrodes, carbon nanotubes, etc.
