A new vaccine that can help fight diverse strains of the flu and protect one against flu have been found, claims a research. You can't get the flu from the shot because the vaccine contains viruses that are inactivated or severely weakened.
The vaccine at the health department covers the two type-A strains and two type-B strains expected to be circulating this year.
The idea is to use an ancestral form of the influenza virus in a vaccine.
"The flu shot is safe, free, widely available, and is proven to reduce the number of doctor visits, hospitalizations and deaths related to flu", Kim Presta, a manager in the health unit's clinical services division, said in a release. They are antigenically similar to the strain of vaccine. "When we compared that to a traditional flu vaccine either flu mist or flu zone we got superior protection and the mice were able to survive against 7 out of 9 lethal influenza challenges", Weaver said.
The egg method allows for large-scale manufacturing but is unreliable. Those that received higher doses of the vaccine didn't even get sick.
"Some of the hospitals in York Region have developed their own in-house campaign and have accessed our staff to support them in providing infection prevention and control education on the importance of influenza immunizations", the email said. The molecule is a type of sugar, hence the reason it's being called a glycosylation site. When we're exposed to the proteins that form the outer layer of a killed flu virus, we generate antibodies that are ready to attack flu viruses whenever they reappear. The vaccine is made from an inactivated virus that can not transmit infection. It takes about two weeks after vaccination for the immune system to become protected.
"Our experiments suggest that influenza virus antigens grown in systems other than eggs are more likely to elicit protective antibody responses against H3N2 viruses that are now circulating", Hensley said. That's because current H3N2 viruses "don't grow well in chicken eggs, and it is impossible to grow these viruses in eggs without adaptive mutations", Scott Hensley, Ph.D., an associate professor of microbiology at Penn, said in a statement.
