If vaccines are safe, why is there an age limit on some? If vaccines are safe, why would they harm someone with a weakened immune system? If you have a weakened immune system, will you know it BEFORE you get the shot?
Bonus question - why do they give the Hep B vaccine the day you're borne, even though the risk of Hep B is primarily in the IV drug user and prostitute community?
Second bonus question - do you feel happier thinking of yourself in a government herd or as an individual? Explain in 50 words or less.
“If vaccines are safe, why is there an age limit on some? If vaccines are safe, why would they harm someone with a weakened immune system? If you have a weakened immune system, will you know it BEFORE you get the shot?”
Vaccines work by stimulating the immune system to respond, in the same/similar way it would respond to the actual illness being vaccinated against (creating antibodies, etc.). If the immune system is not fully developed (e.g., in very young babies), or is compromised, that immune response may not happen. So, it’s not necessarily that vaccines are not safe for babies and people with compromised immune systems, just that they are not effective (or as effective) for those people.
