- Inactivated vaccines. Inactivated vaccines use the killed version of the germ that causes a disease. Inactivated vaccines usually don’t provide immunity (protection) that’s as strong as live vaccines.
- Live-attenuated vaccines. Live vaccines use a weakened (or attenuated) form of the germ that causes a disease. Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response.
- Messenger RNA vaccines—also called mRNA vaccines. Researchers have been studying and working with mRNA vaccines for decades and this technology was used to make some of the COVID-19 vaccines.
- Subunit, recombinant, polysaccharide, and conjugate vaccines. Subunit, recombinant, polysaccharide, and conjugate vaccines use specific pieces of the germ—like its protein, sugar, or capsid (a casing around the germ).

Vaccines were first developed at the end of the 19th century. The practice of variolation (inoculating an uninfected person with pus from an infected person) was commonly used during the 18th century to prevent bacterial infections like smallpox, and it was also sometimes used for preventing diseases during outbreaks, such as typhoid, plague, and c...
There are 85 single and combination vaccines approved for use by the U.S. Food and Drug Administration (FDA).Among these are the many inactivated vaccines, also known as whole-killed vaccines, that protect against the following diseases: 1. Hepatitis A(given by injection in two doses) 2. Influenza (given as a flu shotannually) 3. Japanese encephali...
There are pros and cons to every vaccine. In many cases, there is only one version of a vaccine to choose from. Even so, understanding how inactivated vaccines work can help you understand why vaccine doses differ and why some cost more than others.
Vaccines are among the greatest achievements of medical science. Irrespective of their type, the benefits—in terms of prevention of disease, illness, and death—greatly outweigh the risks. The avoidance of vaccines not only places you or your child at risk but threatens the resurgence of diseases once thought eliminated. Such is the case with measle...
An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then killed to destroy disease-producing capacity.
Mar 17, 2021 · Inactivated vaccines are another form of vaccine, where the virus is inactivated during the process of making the vaccine. Inactivated vaccines are not strongly influenced by antibodies in the...
Inactivated vaccines have been used for over a century to induce protection against viral pathogens. This established approach of vaccine production is relatively straightforward to achieve and there is an augmented safety profile as compared to their live counterparts.

Sep 1, 2021 · The adjusted vaccine effectiveness in the fully immunized group of persons 60 years of age or older was 66.6% (95% CI, 65.4 to 67.8) against Covid-19 and was 85.3% (95% CI, 84.3 to 86.3) against...
May 8, 2024 · Inactivated vaccines are antigenic substances composed of inactivated material from a pathogen, such as a virus or bacterium. When administered, inactivated vaccines elicit protective...
