time to develop h1n1 vaccine

"We are moving things around to accommodate this and getting our raw materials ready and having our scientists ready.

DNA and mRNA vaccines are chemically synthesized as these types of candidates don’t require the virus to be replicated. First, it has been identified that the SARS-CoV-2 virus behind the COVID-19 does not replicate in such eggs.

Coronavirus has thrown a challenge before the human intelligence and a prompt, as well as effective retaliation, must come in the form of COVID-19 vaccine. That's because flu-vaccine production — whether for swine or seasonal flu — is time-consuming and laborious, requiring vaccine makers to grow millions of copies of the flu virus in chicken eggs, then purify those bugs into a ready-to-inject formula safe for patients. Data showed 477 deaths with lab-confirmed 2009 H1N1 flu in the U.S. had been reported to CDC as of August 8, 2009.

(The SNS, maintained jointly by the Department of Homeland Security and the Department of Health and Human Services, is the nation's emergency medicine chest, containing critical drugs and medical equipment to be used in a public-health emergency.)

COVAXIN co-maker Bharat Biotech is testing an inactivated virus. While it takes years of research and testing to produce a vaccine, scientists are coming up with new methods in order to expedite the development process of COVID-19 vaccine. Using this method, a vaccine for the 2009 H1N1 virus could be in production in 10 to 12 weeks, rather than the usual four to six months. The science of vaccine development has advanced since the 2009 outbreak of H1N1 or swine flu. The company stands ready to try its strategy against swine flu if needed. Although the stockpiled antiviral drugs can treat existing cases of flu, a vaccine is the only way to protect people who are uninfected and halt further spread of the virus.The CDC, the only agency that possesses the virus needed to make a vaccine, says it is still "looking very intently" at a swine flu vaccine, but it has not yet given the green light to scale up production. "As long as we get the genetic sequence of some viral proteins, it doesn't matter where the virus came from — human, swine or bird," says Singhvi.

(But even if the CDC's seed stock of virus were to be released to vaccine makers today, it would take the companies anywhere from four to six months before the first inoculation could be ready for public use.

After the immunization program was terminated nine months after it began, government officials paid $90 million in damages to patients who were injured by the vaccine. It had adopted a 70-year-old technique of injecting a flu virus into a fertilised hen’s egg. Richard Besser, acting director of the Centers for Disease Control and Prevention (CDC), said the agency has begun cultivating the seed stock of virus needed for a swine flu vaccine. Around the world, researchers are working on more than 165 potential Coronavirus vaccines, out of which around 27 have managed to reach the different stages of human trials. Nevertheless, Cary is confident: "We have two plants that both have the capability of producing what the U.S. market demand is for the seasonal and swine influenza vaccine," she says. For example, Oxford-AstraZeneca’s Coronavirus candidate is DNA-based while Moderna’s is mRNA-based. This is the same way the recently developed vaccine against human papilloma virus, Gardasil, works. These antibodies are robust enough to fight off the actual virus should an immunized person become infected. Serum, which has tied up with Oxford-AstraZeneca to mass-produce the potential vaccine COVISHIELD in India, has received approval from the Drugs Controller General of India to conduct Phase II and III human clinical trials in the country.During the swine flu (H1N1) pandemic, Serum was asked to develop a vaccine. Subsequently, the egg acts as hot helping the growth of the virus and replicated virus is developed.
