When will a vaccine against the coronavirus come? This is a complicated question that we cannot answer until the first vaccine found to be safe and effective has gone through the appropriate channels and oversights. While “vaccines” are reportedly given in China and Russia, any COVID vaccine you receive in the US must be FDA cleared.
Once a drug is approved, it will take time to manufacture and distribute – not everyone can get a vaccine right away.
The US could receive multiple vaccines by the end of the year, according to the Washington Post, according to Robert Wachter, chairman of the medical department at the University of California at San Francisco. That would be just a year after the discovery of SARS-CoV-2, the official name of the virus that causes COVID-19 disease. Vaccine development can often take decades.
Getting one or more vaccines through clinical trials for FDA approval, however, is only the first leg of the journey. The next thing is to convince people to take it. Sixty-three percent of adults in the United States have raised safety concerns about a coronavirus vaccine. 40 percent of those questioned expressly feared that its rapid development had taken place to According to an October 19 Harris poll, some people are reportedly concerned about possible side effects.
Track the coronavirus pandemic.
There are currently 59 coronavirus vaccines in various stages of clinical trials, a handful of which are almost ready to apply for approval. Most experts believe we will have several ready to distribute by early 2021, but life may not return to normal until 2022.
The FDA said in June it won’t approve a vaccine that doesn’t work at least half the time, but some scientists have questioned whether this is a sufficiently effective target. The hope is that out of a field of dozens of candidates, at least some will do better than half the time.

Important news about COVID-19 vaccines
The development of COVID vaccines is becoming increasingly important
Various acceleration efforts are currently underway, such as the White House’s Operation Warp Speed, which aims to cut red tape in order to speed up vaccine development and be ready to distribute vaccines once they get FDA approval. So far, the U.S. government has pledged over $ 10 billion to several vaccine manufacturers for a total of 800 million vaccine doses.
Vaccines typically take around 10 to 15 years to develop and approve. This is done in four phases, which include human experiments. Operation Warp Speed, however, allows approved vaccine projects to submit piece-by-piece data to the FDA rather than submitting all of the data from a four-phase study at once.
In the meantime, the program is also funding efforts to begin making cans while clinical trials are ongoing. That is, by the time these vaccines are approved there will already be a supply of doses that can be distributed nationally.
“I would hope that the companies will have delivered the promised hundreds of millions of doses by well into the second half of 2021,” said Dr. Anthony Fauci, director of the National Institute for Allergies and Infectious Diseases, told Forbes in August. As recently as October, Fauci seemed convinced of such a schedule.
Promising coronavirus vaccines from the UK, US and China
Here’s a quick look at some of the frontrunners in the race for a vaccine against COVID-19, including where the vaccines are located, where they will be tested, and how scientists believe that, if known, they are ready for widespread use.
Oxford University / AstraZeneca (Great Britain): AstraZeneca has resumed testing of its vaccine, which began with 100,000 volunteers in at least three countries. The lead researcher Dr. Sarah Gilbert originally said AstraZeneca was aiming for a fall 2020 release, and while that may be optimistic at this point, it doesn’t seem to have been significantly delayed.
Modern (USA): An apparent dispute with state regulators delayed large-scale human testing, but Moderna’s CEO has told Barron’s that he continues to expect the company to know if the vaccine is safe and effective by Thanksgiving. He says Moderna should be able to distribute it in early 2021 if it does.
Pfizer (USA): Although the four COVID-19 vaccine candidates are still in early human trials, two of them have been accelerated by the FDA. Pfizer’s goal is to distribute 100 million cans in 2020 and an additional 1.3 billion in 2021.

Vaccines, antibody tests, treatments: the science of …
SinoVac (China): The vaccine is currently being tested on around 10,000 volunteers in China and around 9,000 in Brazil. Tests are to be carried out on around 1,900 test subjects in Indonesia shortly. The CEO of BioPharma, SinoVac’s Indonesian partner, expects the vaccine to be ready in early 2021.
SinoPharm (China): The state-owned company is currently testing around 15,000 volunteers in the Middle East in a test that is expected to take three to six months. Initial results suggest that the drug is safe and at least reasonably effective. SinoPharm recently built a second facility to manufacture the vaccine and doubled its capacity to around 200 million doses per year.
CanSino Biologics (China): CanSino’s vaccine is slated to begin large-scale human trials this summer and has already been approved for the Chinese military. The vaccine is based on a modified cold virus that some experts warn may be less effective than other vaccine efforts.
Will there be only one vaccine for everyone?
We probably won’t know until next year, but Fauci has suggested that several different vaccines, made and sold by different laboratories, might be required to end the pandemic. This was published in an article published in Science magazine on May 11th. He has also said that he has different vaccines for different groups of patients. For example, one vaccine for elderly or other high-risk patients, another for healthy adults, another for children, etc.
What if we never find a coronavirus vaccine?
Coronaviruses are a large class of viruses and there are currently no vaccines for them. While there are promising early results, there is no guarantee of a vaccine until 2021. Statistically, only about 6% of vaccine candidates ever make it to market, according to an April Reuters report.
Early evidence suggests that the coronavirus doesn’t seem to mutate as quickly or frequently as the flu, and it is believed that the virus has not yet mutated significantly enough to disrupt vaccine development – although our knowledge may change.
The longer we go without a vaccine, the more likely the focus will be on treatments like that try antiviral drugs Medikament Remdesivir, which has reportedly shown promising results, and Dexamethason, a steroid that doctors say increases survival rates among the most serious of cases. With effective therapeutic treatments, many viruses that used to be fatal are no longer death sentences. For example, thanks to tremendous advances in treatment, patients with HIV can now expect the same life expectancy as non-HIV positive people.
Eventually, the world population may reach the rate required for 60% to 70% Herdenimmunität Protecting those who are not immune, which is the ultimate goal of a vaccine.
