There is a quadrivalent flu shot that can be given to children as young as 6 months old. Flucelvax Quadrivalent is now approved for people 6 months and older. Influenza Vaccine Products for the Season. The quadrivalent nasal spray vaccine is approved for use in non-pregnant individuals, 2 years through 49 years old.
People with certain medical conditions should not receive the nasal spray influenza vaccine. Different influenza flu vaccines are approved for use in people in different age groups. In addition, some vaccines are not recommended for certain groups of people. There are many vaccine options to choose from, but the most important thing is for all people 6 months and older to get a flu vaccine every year. If you have questions about which vaccine is best for you, talk to your doctor or other health care professional.
All flu vaccine for the season is quadrivalent. Abstract Seasonal influenza vaccination is one of the most common medical procedures and yet the extent to which it activates the immune system beyond inducing antibody production is not well understood.
Introduction Influenza is a viral respiratory pathogen that causes substantial morbidity and mortality worldwide. Cells and stimuli Freshly isolated human whole-blood was collected into heparinized vacutainers BD and used intact or washed with room temperature RPMI media Life Technologies 2—3 times to generate plasma-depleted whole-blood. Open in a separate window. Figure 1. Figure 2. Figure 3. Influenza protein derived immune complexes are responsible for SV induced activity ex vivo While investigating the mechanisms through which SV stimulates human immune cells, it was observed that SV could not stimulate peripheral blood mononuclear cells PBMCs under standard tissue culture conditions Figure 4A.
Figure 4. Figure 5. Influenza vaccine formulations vary in proteomic responses We evaluated if SV induced cytokine secretion was also dependent on human serum using luminex Figure 6A. Figure 6. Discussion Blood transcriptional activity induced by in vivo SV immunization is detectable within hours and peaks a day after vaccination [ 15 ]. Supplementary Material supplement Click here to view.

High-dimensional proteomic profiling of human whole-blood using Cytometry by Time-of-Flight CyTOF was used to compare signaling pathway activation and cytokine production between the split influenza vaccine and a prototypical TLR response ex vivo.
This analysis revealed that the split vaccine rapidly and potently activates multiple immune cell types but yields a proteomic signature quite distinct from TLR activation.
