Success against smallpox and near-success against polio sit beside harder targets such as HIV and a universal flu shot. A public rabies vaccination of Joseph Meister becomes a founding legend of the lab-vaccine era. (5)
Decades of lipid-nanoparticle and mRNA work meet a pandemic; emergency authorizations arrive in December. A first encounter — infection or vaccine — recruits innate cells that display antigen to lymphocytes in lymph nodes.

Success against smallpox and near-success against polio sit beside harder targets such as HIV and a universal flu shot. A public rabies vaccination of Joseph Meister becomes a founding legend of the lab-vaccine era.
Decades of lipid-nanoparticle and mRNA work meet a pandemic; emergency authorizations arrive in December. A first encounter — infection or vaccine — recruits innate cells that display antigen to lymphocytes in lymph nodes.
Clones that fit the antigen expand. Some become short-lived effectors; some become memory. Boosters restimulate that file. Inactivated, live-attenuated, subunit, viral-vector and mRNA platforms differ in how antigen is shown, not in the idea of memory.
Most encounters with vaccines are appointments, not emergencies. The useful household skill is keeping a record and knowing where local advice lives. Everyday talk should separate mild expected reactions from reasons to seek care — a clinician draws that line for a person.
This is education from the atlas. It does not diagnose and does not prescribe a dose. It does not replace the full topic page.
