Chapter 10: Smallpox, Measles, and the Anti-Vaccine Debate

These flashcards will help you understand key terms and concepts discussed in Chapter 10 about smallpox, measles, and the anti-vaccine debate.

Smallpox

A highly contagious and dangerous viral disease caused by the Variola major virus, leading to high mortality and disfiguring scars.

Variolation

The predecessor to vaccination, where pus from a weak smallpox case was introduced to a non-immune person to induce a mild case of smallpox.

Vaccinia

The virus used in the smallpox vaccine, originally believed to be cowpox, but identified as a different virus altogether.

Ring Vaccination

A strategy for controlling disease outbreaks by vaccinating all individuals exposed to an infected person and those in surrounding areas to create a firewall.

Interferons

Proteins secreted by human cells to signal infection and inhibit viral replication, targeted by poxviruses to evade immune response.

Epidemiology

The study of how diseases spread and can be controlled in populations.

Measles Virus (MV)

A highly infectious virus that primarily infects humans, causing serious illness and lifelong immunity in survivors.

Herd Immunity

The protection from disease that occurs when a sufficient percentage of a population is immune, reducing transmission even among non-immune individuals.

Monkeypox

A viral disease similar to smallpox, causing renewed interest in smallpox vaccines due to its transmission and mortality risks.

Moral Debate

Discussions regarding the ethical implications of vaccination practices, including variolation and modern vaccination mandates.

Polio Wards

Hospitals or healthcare facilities specifically for treating polio patients, notably less common due to successful vaccination efforts.

Public Health Campaigns

Organized efforts to promote health measures, including vaccination campaigns during outbreaks to control disease spread.

Bifurcated Needle

An inexpensive needle designed to deliver the smallpox vaccine efficiently through the skin.

Autism Controversy

The debate surrounding alleged links between vaccines, particularly the MMR vaccine, and autism, largely debunked by scientific studies.

Vaccine Hesitancy

Reluctance or refusal to vaccinate despite availability of vaccines, influenced by various social and cultural factors.
