As COVID-19 continues to infect others around the world and no slowdown is seen, hope rests on the dozens of imaginable vaccines that are developing recently.
Like the annual influenza vaccine or MMR vaccine (measles, mumps and rubella), an effective COVID-19 vaccine would provide some form of immunity and prevent the virus from spreading further, but it remains to be noted whether this is imaginable, as well as when .
Here’s what you want to know about the newest COVID-19 vaccines in progression and how they work.
What is a vaccine?
A vaccine is formulated to prepare the framework’s immune formula to fight a destructive virus or bacteria. An edition of the virus is introduced through the vaccine so that the immune formula can be reported to defeat it, regularly by forming antibodies.
How many vaccines are being developed for COVID-19?
There are 38 other vaccines that are being tested lately in human clinical trials, nine of which are in development phase 3, that have passed early protection trials and are now part of giant clinical trials with thousands of participants; at least another 93 are being tested lately. in animals, according to the New York Times.
What are the most promising?
There are several encouraging applicants around the world, and the United States has invested in at least seven corporations to help fund its trials. While any vaccine can be used in the United States, the government will first have to reach an agreement with the vaccine manufacturer. Two U. S. -funded corporations, Pfizer and Moderna, are in Phase 3 clinical trials and appear to be the most powerful candidates for the United States.
Pfizer’s vaccine, a collaboration with The German company BioNTech and the Chinese company Fosun Pharma, worked well in the first tests with only minor side effects such as fever and fatigue, the Times reported. volunteers in the United States, Argentina, Brazil and Germany. A senior Pfizer executive said the company will likely know through October if the vaccine is effective and will produce more than 1. 3 billion doses by the end of 2021.

The Moderna vaccine is a component of a partnership with the National Institutes of Health and began human clinical trials in March. His vaccine also looks promising and Moderna is conducting trials in 30,000 Americans. So far, more of the volunteer component have had side effects, however, they were also minor, such as fatigue, chills, headaches and muscle aches, CNN reported.
In any of the vaccine trials, some of the 30,000 participants gained a placebo injection of salt water than a real dose of the vaccine. This allows researchers to see how other people who are vaccinated against those who are not reacting.
Another promising vaccine, from AstraZeneca and the University of Oxford, initiated Phase 3 trials in Brazil, England, India, South Africa and the United States after initial trials showed that it produced antibodies opposed to COVID-19 without serious side effects. On September 8, AstraZeneca had to suspend global testing after a player developed inflammation; However, this is not an unusual practice in vaccine testing, while researchers whether the player’s reaction is due to the dose of the vaccine or an unrelated problem, and WHO Chief Scientist Dr. Soumya Swaminathan said he is not “too discouraged” because “these things happen,” CNBC reported.

Will the vaccine be safe?
Yes, extensive and lengthy clinical trials underway are all components of the extensive steps vaccine brands are taking to make your product absolutely safe. On September 8, nine major vaccine brands, adding Pfizer and Moderna, signed a promise to meet “high moral standards” and not rush vaccine production until proven effective.
Corporations stated that they would “submit for emergency use approval or authorization after demonstrating protection and effectiveness through a Phase 3 clinical examination designed and conducted to meet the needs of qualified regulators such as the FDA,” CNN reported.

The promise comes after President Donald Trump asked the CDC to prepare to start distributing a COVID-19 vaccine on November 1, two days before the 2020 election, and before the idea of the experts it would be ready.
Pfizer CEO Albert Bourla said today that corporations have created this commitment because of “growing public considerations about the processes we use to expand those vaccines and, more importantly, the processes that will be used to compare these vaccines. that “the only rival here is the virus. “
Who will get the vaccine first?
The CDC has formed a federal advisory committee on who deserves to get the vaccine first. According to the Washington Post, others in high-risk populations, adding fitness care and other essential workers, the elderly, others living in – long-term care services, and others with severe fitness disorders – are likely to take precedence.
Can other people who have already had COVID-19 not get vaccinated?
No, while the one who has already recovered from the virus hopefully has antibodies, not everyone has antibodies, and experts still don’t know if they’ll be offering immunity against it again. In addition, coVID-19 antibodies are not known to last.
