I haven't seen that kind of backlash for the vaccines measles, mumps, rubella fever, small pox, bird flu, swine flu, hepatitis A or Hepatitis B, Chicken Pox, shingles, or even the AIDs vaccine.
You're saying "they always blame vaccine etc" but have only provided information about what you say people do.
Provide ARTICLES that massively talk about the failures of any of the vaccines above... Because I've been around since 1978 and don't recall any of the backlash you're talking about, for any vaccine that has came out.... Except for the COVID vaccines.
