Adults 65 years of age and older can have a weaker immune response to flu vaccines, making them more likely to get sick with the flu or get flu complications even when vaccinated, according to the ...
During the worldwide Spanish flu pandemic of 1918, "Pharmacists tried everything they knew, everything they had ever heard of, from the ancient art of bleeding patients, to administering oxygen, to developing new vaccines and serums (chiefly against what we call Hemophilus influenzae – a name derived from the fact that it was originally considered the etiological agent – and several types ...

A 2021 study found the common flu vaccine provided immunity to the flu in 58% of recipients. [6] The measles vaccine fails to provide immunity to 2% of children that receive the vaccine. However, if herd immunity exists, it typically prevents individuals who are ineffectively vaccinated from contracting the disease. [ 7 ]
Denaturing the protein may 'disarm' its function but allow the immune system to have an immune response thus creating an immunity without harming the patient. Cross reactivity has implications for flu vaccination because of the large number of strains of flu, as antigens produced in response to one strain may confer protection to different ...
