Artificial active immunity is achieved through vaccination. This means introducing a weakened or inactive form of a pathogen (or its components) into the body to stimulate an immune response. Here are some examples:
Vaccines for common diseases:
* Measles, Mumps, Rubella (MMR) vaccine: A live, attenuated virus vaccine that protects against these highly contagious diseases.
* Diphtheria, Tetanus, Pertussis (DTaP) vaccine: A combination vaccine containing inactivated toxins and bacteria to protect against these serious diseases.
* Polio vaccine: Available in two forms: inactivated poliovirus vaccine (IPV) and oral poliovirus vaccine (OPV), both offering protection from polio.
* Hepatitis B vaccine: A vaccine that protects against infection with the Hepatitis B virus, which can cause serious liver disease.
* Influenza (flu) vaccine: A yearly vaccine containing inactivated influenza viruses to protect against seasonal flu strains.
* Human Papillomavirus (HPV) vaccine: A vaccine that protects against infection with HPV, a virus that can cause cervical cancer.
* Meningitis vaccines: Various vaccines are available to protect against different types of bacterial meningitis.
* Pneumococcal vaccine: A vaccine that protects against infections caused by Streptococcus pneumoniae bacteria.
Newer vaccine technologies:
* mRNA vaccines: Like the COVID-19 vaccines, these utilize messenger RNA to instruct the body to produce viral proteins, triggering an immune response without using the actual virus.
* Recombinant protein vaccines: These vaccines use genetically engineered proteins to trigger an immune response.
* Viral vector vaccines: These vaccines use harmless viruses as carriers to deliver genetic material encoding viral antigens, stimulating the immune system.
These are just some examples, and there are many other vaccines available to prevent various infectious diseases.
Important note: While vaccines are highly effective in preventing diseases, they are not 100% guaranteed to prevent infection. It is still important to maintain good hygiene practices and follow other health recommendations.
