Vaccine shedding is a form of viral shedding [1] [2] which can occasionally occur following a viral infection caused by an attenuated (or "live virus") vaccine. Illness in others resulting from transmission through this type of viral shedding is rare. [3] [4] The idea of shedding is a popular anti-vaccination myth. [5]
The term is variously used to refer to viral particles shedding from a single cell, from one part of the body into another, [2] and from a body into the environment, where the virus may infect another. [3] Vaccine shedding is a form of viral shedding which can occur in instances of infection caused by some attenuated (or "live virus") vaccines.
Flattening the curve is a public health strategy to slow down the spread of an epidemic, used against the SARS-CoV-2 virus during the early stages of the COVID-19 pandemic. The curve being flattened is the epidemic curve, a visual representation of the number of infected people needing health care over time. During an epidemic, a health care ...
“The updated vaccine is closer to JN.1 than our old vaccine,” Dr. Russo says. “The hope is that, even if we see more cases with JN.1, the updated vaccine will protect against severe disease.”
And, of course, if you develop symptoms of the virus, it’s a good idea to test yourself to see if you have the virus so you can lower the odds you’ll spread it to others.
Children are much more infectious than adults and shed virus from just before they develop symptoms until two weeks after infection. [1] [2] The transmission of influenza can be modeled mathematically, which helps predict how the virus will spread in a population. [3] Influenza can be spread in three main ways: [4] [5]
“You may be starting to feel symptoms because your immune system is activating, but the virus might not yet be high enough in your nose to cause a test to turn positive," Mina says. In this ...
An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). [1] Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. [2] These vaccines contrast to those produced by "killing" the pathogen ...
