  The creator of AstraZeneca's coronavirus vaccine is a mum to triplets. Her children participated in the trial. AstraZeneca and the University of Oxford announced Monday that their COVID-19 vaccine was 70% effective, on average. The vaccine's creator, Sarah Gilbert, had faith in its efficacy from the start: Her triplets participated in the UK trial. "This vaccine should do what we always wanted it to do," Gilbert said on Monday. "We wanted a vaccine for the world, not just for high-income countries."

However, a COVID - 19 vaccine may not be available for young children until more studies are completed. CDC is working with partners across the country to make sure people have the information they need to be confident in deciding to get vaccinated .

Facts First: It remains unclear if those already infected with the virus are immune to any reinfection. Additionally, it' s unknown how long any sort of immunity would "Yes, the grand majority of people that have had Covid - 19 do develop an antibody response," Gordon said. "However, although the scientific

COVID-19 cases continue to hit daily records in the U.S., and vaccines are on the horizon.

Pfizer/BioNTech and Moderna are the leaders in creating FDA-approved vaccines, with Pfizer's showing a 95 percent efficacy rate and Moderna's at 94.1 percent. No vaccine has been approved in the U.S. as of December 1, but both developers applied for emergency use authorizations through the Food and Drug Administration (FDA) in late November. Both companies said their vaccines will require an initial dose and a booster a few weeks later.

The Question

Now that vaccines appear imminent, people are asking if being vaccinated is needed if they already have been diagnosed with COVID-19.

In China, nearly 1 million people have reportedly already gotten a coronavirus vaccine

  In China, nearly 1 million people have reportedly already gotten a coronavirus vaccine China’s emergency vaccine program is a risky proof of concept for large-scale Covid-19 vaccine deployment.The vaccinations have occurred as part of an emergency use program that began in late July, though few details about it have been revealed by the Chinese government. What we do know is that as part of the program, China’s State Council authorized high-risk groups including medical workers, customs officials, and transportation workers to start receiving one of three Chinese-made vaccines — two from Sinopharm and one produced by Sinovac. But some Chinese cities have also been offering the vaccines to members of the public.

Russia has over 20 years of experience in developing technology for producing vaccines . This helped to create the unique Covid - 19 vaccine in a very short period of Having a technological platform and understanding of what is transmitting the virus , you can design a vaccine against almost any disease.

Since COVID - 19 coronavirus vaccines are still under development, now is the time to set vaccine To stop the pandemic, the number of new infections per day needs to drop to zero, or at least to a So, when 5% of the population has already been infected with the virus , the best that you can do is

Since the initial coronavirus outbreak in the U.S. earlier this year, approximately 13.6 million cases have been reported across the nation, according to the Centers for Disease Control (CDC). But are coronavirus antibodies strong enough to give an individual previously diagnosed with COVID-19 immunity from the virus?

The CDC's website suggests that early evidence proposes the idea that the antibodies of the coronavirus "may not last very long." However, they cannot comment on the issue until a vaccine is provided and they are given recommendations by the Advisory Committee on Immunization Practices (ACIP).

The Facts

On December 2, Operation Warp Speed (OWS), which is a government public-private partnership put together to facilitate development, manufacturing and distribution of 300 million safe doses of COVID-19 vaccine by January, held a briefing regarding the coronavirus pandemic.

Dr. Moncef Slaoui, scientific head of OWS, referred to the current vaccine trials and how they have affected those participating.

"Here are the facts. In the trials, people were recruited on the basis of not having had COVID, clinical COVID disease, so symptoms, etc.," Slaoui said. "On that basis they were recruited, it turns out anywhere between 5 and 10 percent of the subjects recruited were zero positive to COVID-19. In other words, they most likely had asymptomatic or very mildly symptomatic disease and didn't notice it.

"So what we know is that the vaccines are safe in these populations, and quite significant numbers of zero positives have been immunized and their immune responses are being analyzed."

Dr. Mark Siedner, an infectious disease clinician and clinical epidemiologist at Massachusetts General Hospital, agreed that there is not enough evidence to know if the vaccination benefits those with prior infection.

"On one hand, we know that some people, and particularly those with poor immune systems, appear to remain at risk for re-infection," Siedner told Newsweek. "But on the other hand, re-infection appears to be an incredibly rare phenomenon. There are only a handful of cases in the literature."

The first batch of coronavirus vaccines, once approved, are expected to be enough for 20 million people, less than the amount of frontline and high-risk individuals in the country.

"The decision whether or not to vaccinate those previously infected has completely different implications for the top two groups on the vaccination priority list: older individuals in long-term care facilities and healthcare workers," Siedner said. "For the former, vaccination primarily serves the purpose of preventing severe disease. But for the latter, vaccination is most important for prevention of transmission to others."

How Australia's planned COVID-19 vaccine rollout compares to United Kingdom, United States and Russia's coronavirus response

  How Australia's planned COVID-19 vaccine rollout compares to United Kingdom, United States and Russia's coronavirus response How does Australia place in its planned COVID-19 vaccine rollout compared to the rest of the world? Here's where some of the prominent global players and our closest neighbours stand. AustraliaThe Federal Government says it is prioritising the safety of Australians, as it waits on four vaccine candidates to pass certain stages in their approval process.The Australian Government has signed a deal to take 10 million doses of the Pfizer vaccine, which will cover 5 million people based on the two doses needed.

That is a major reason why the uncertainty of the effect the COVID-19 vaccines might have on those who have previously contracted the virus is a crucial question that needs to be answered, Siedner said.

"We need to remember that many of those infected previously are those who have been in the trenches, at the front line of the epidemic as healthcare workers, grocery workers, first responders, other essential workers, and under-represented minorities in geographic locations without sufficient healthcare access," he said.

"Deciding to exclude these individuals from a beneficial public health response program should not be taken lightly or it might only exacerbate many of the healthcare inequities that the COVID-19 epidemic has only illuminated."

The Answer


The lifespan of the coronavirus antibodies has not yet been identified, but how long a vaccine is effective also is unknown, experts said. The vaccine might protect people for weeks, months or years, but no one knows how long it will fight the virus, said Dr. James Yoon, an infectious disease specialist at New York-Presbyterian Hospital.

Once a vaccine is approved and distributed, experts recommend that everyone is vaccinated, beginning with high-risk individuals and front-line workers.
