Vaccines, that’s why women have more side effects

If you are female and you go for the flu vaccine with your partner-brother-child and you get a low-grade fever and maybe even pain in your arm and instead the males seem unscathed, don’t worry. Because not only is it biologically normal but it is also an advantage for women. An advantage that has been granted to females of any species on the planet to ensure the survival of the species itself.
