What Are Vaccines and How Do They Work?

Vaccines are biological preparations that provide immunity to specific diseases. They work by stimulating the body’s immune system to recognize and combat pathogens, such as viruses or bacteria, without causing the disease itself.

The main points about vaccines include:
1. Types of vaccines
2. Mechanism of action
3. Importance of herd immunity
4. Vaccine hesitancy
5. Recent advancements in vaccine technology

Understanding vaccines further reveals their complexity and impact on public health.

  1. Types of Vaccines:
    Types of vaccines include live-attenuated vaccines, inactivated vaccines, subunit/purified vaccines, and messenger RNA (mRNA) vaccines. Live-attenuated vaccines contain weakened forms of microbes, such as the measles vaccine. Inactivated vaccines contain killed pathogens, like the polio vaccine. Subunit vaccines include only parts of the pathogen, as seen in the hepatitis B vaccine. mRNA vaccines, like those developed for COVID-19, use genetic material to instruct cells to produce a harmless piece of the virus, prompting an immune response.

  2. Mechanism of Action:
    The mechanism of action of vaccines involves identifying pathogens and eliciting a suitable immune response. When vaccinated, the immune system recognizes the antigen—an inactive form of the pathogen—and produces antibodies. These antibodies remain in the bloodstream. If the body encounters the actual pathogen later, these antibodies trigger a swift response, preventing illness. A study by Plotkin (2020) emphasizes that this ability to ‘remember’ pathogens is essential in providing long-term immunity.

  3. Importance of Herd Immunity:
    The importance of herd immunity lies in protecting those who cannot be vaccinated. Herd immunity occurs when a significant proportion of a community is immune to a disease, thereby reducing its spread. The World Health Organization states that vaccination rates must reach about 95% for diseases like measles to provide herd immunity. This protects vulnerable populations, including infants and immunocompromised individuals, by hindering the disease’s transmission.

  4. Vaccine Hesitancy:
    Vaccine hesitancy refers to the reluctance to vaccinate despite availability. Factors contributing to vaccine hesitancy include misinformation, safety concerns, and distrust in healthcare systems. The WHO identifies vaccine hesitancy as one of the top threats to global health. An article by Larson et al. (2014) notes that addressing misinformation and engaging with communities effectively can help to improve vaccination rates.

  5. Recent Advancements in Vaccine Technology:
    Recent advancements in vaccine technology offer new methods for preventing infectious diseases. mRNA technology, utilized in COVID-19 vaccines, allows for rapid development and production.
