Influenza B virus. Influenza B virus is the only species in the genus Betainfluenzavirus in the virus family Orthomyxoviridae . Influenza B virus is only known to infect certain mammal species, including humans, ferrets, pigs, and seals. [ 4][ 5] This limited host range is apparently responsible for the lack of influenza pandemics associated ...
Polyvalent influenza vaccine. Polyvalent influenza vaccine is a type of influenza vaccine that provides immunity against more than one type of antigen. [1] In the second week after receiving the flu shot, the body's immune system is triggered by the antigens so the body starts producing antibodies. These antibodies help fight against influenza ...
Influenza, commonly known as " the flu " or just " flu ", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin one to four (typically two) days after exposure to the virus and last for about ...
Fluzone is typically administered in a single dose by intramuscular injection; [20] an intradermal injection is also available. [21] It is presented as a 0.25 ml syringe for pediatric use, as a 0.5 ml syringe for adults and children, as a 0.5 ml vial for adults and children, and as a 5 ml vial for adults and children. [20]
D04536. Influenza vaccines, colloquially known as flu shots, are vaccines that protect against infection by influenza viruses. [ 14][ 15] New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. [ 14] While their effectiveness varies from year to year, most provide modest to high protection against ...
The schedule for childhood immunizations in the United States is published by the Centers for Disease Control and Prevention (CDC). [ 1] The vaccination schedule is broken down by age: birth to six years of age, seven to eighteen, and adults nineteen and older. Childhood immunizations are key in preventing diseases with epidemic potential.
Example Polish call for vaccination against Diphtheria and Tetanus. Global vaccination coverage 1980 to 2019 among one year olds [1]. A vaccination schedule is a series of vaccinations, including the timing of all doses, which may be either recommended or compulsory, depending on the country of residence.
Recombinant live vaccine. Live recombinant vaccines are biological preparations that stimulate immune responses to a pathogen through the use of genetically modified live bacteria or viruses. These live pathogens are biologically engineered to express exogenous antigens in the cytoplasm of target cells, thereby triggering immune responses. [1]
