Children in whom the vaccine is 100% effective protect those few who have not been completely immunized -- lessening everyone's chance of exposure to the disease. Researchers found no consistent differences in antibody responses between participants that received ccIIV and those who received the egg-based IIV. 2008 Sep;110(3 Suppl 2):S4-7. Recombinant vector vaccines in vaccinology.
Advantages And Disadvantages Of Live Attenuated Vaccines highly specific delivery of antigens to target cells and high expression of antigen after vaccination often a single dose is enough to stimulate long-term protection.
