Live attenuated vaccines

0

When given, these injections mimic an initial infection by causing an immunological action comparable to that caused by the infection, without ever previously triggering the disease or its problems.

Live subcutaneous injections have been available since the 1950s and are prepared from contagious DETAILS representatives that are deteriorated (attenuated) with appropriate therapies and laboratory treatments.

Live injections: what are the risks of transmission of infection by injection?

Thus attenuated, the microorganisms retain their shape, but are no longer capable of triggering the disease. Vaccines, when administered, simulate a first infection: they trigger, in vaccinated persons, an immunological response comparable to that generated by the infection, without however causing the disease or its consequences.

Since online compromised vaccines create a reaction in human beings extremely similar to that caused by a natural infection, they are considered to be good teachers for the body’s immune system and are therefore extremely reliable.

In fact, they produce excellent immunological memory, which is the ability of the body’s immune system to remember microorganisms we have encountered in the past and react quickly. Examples of live attenuated injections:

  • Injection against measles, mumps and rubella (MMR);
  • Chickenpox injection;
  • The rotavirus vaccine

Influenza vaccine given with the nasal spray (the single shot flu vaccine does not include live viruses).

Le vaccin antirotavirus

Although they are extremely effective, not everyone can be vaccinated with this type of vaccine. Children with damaged immune systems, such as those undergoing chemotherapy or immunosuppressive therapy (which minimizes the body’s immune system’s ability to respond to stimuli), cannot be immunized with live mined injections

  • Lately, there has been talk of the risk of contagiousness of vaccinated children, or the threat that vaccinated children transmit the infection contained in the vaccination to other people.
  • In fact, anyone who undergoes any type of inoculation does not send the disease for which they are vaccinated.

This applies to all vaccines, even live attenuated vaccines. The only exception is the varicella vaccine for which 11 cases have been reported worldwide in which immunized people became ill and transmitted a very mild form of varicella.

This extremely rare form of transmission occurs with the vesicles that may contain the infection: just cover them (with long sleeves, pants or a patch) when they come into contact with children or non-immune people or immunocompromised. COVID-19 injections.

Vaccines – news

Since the genetic series of SARS-CoV-2 infection was published on January 11, 2020, scientists, industries and various other companies around the world have been interacting to quickly create safe and effective vaccines against COVID-19.

Some injections use the same innovation (or “system”) as the injections currently in use, others are made using new techniques or strategies recently used in the development of SARS and Ebola vaccines.
