Immunity and Vaccination

by

Immunity is disease resistance and is of following two types:-

  1. Natural or Innate Immunity:- It is present from birth and is inherited from birth by the offspring from the mother.In this form of immunity the response from the organism against the pathogen is immediate in the form of non-specific immune response without the need of recognizing the pathogens.
  2. Acquired or Adaptive Immunity:- It is non- Inherited and is acquired as an enhanced response to a disease during the lifetime of an organism. It takes time to develop and can be more effective in the next encounter with the said Pathogen.The Process of adaptive immunity is the basis of vaccination.

 

Vaccination or immunization:-

  • Vaccination or immunization is based on the property of the memory of the immune system. In vaccination an inactivated on weaknd pathogen is introduced into the body. Vaccine helps in generating the primary immune response whereby immunological memory is established in the body. Vaccine generate memory cell that quickly identifies the pathogen on subsequent exposure and produces a robust secondary immunity response quickly including mass production of antibodies during the actual infection of pathogen.
  • Immune memory formation of antibodies occur on 1st exposure to a specific antigen and secondary response occur after the second exposure to the same antigen. It began very quickly.

Active immunity :-it is immunity which is developed by the person own body either in the form of antibodies or memory cells in response to exposure to living or dead microorganisms. While when preformed antibodies are directly inducted into the body to obtain temporary immunity is called passive immunity.

For example:-The yellow fluid colostrol secreted by mother during the initial days of lactation has abundant antibodies to protect the infant.

Examples of antimicrobial resistance

  1. Increase number of cases of the hospital acquired infection
  2. Multidrug resistant tuberculosis

It was launched in India in collaboration with World Health Organisation to directly observed treatment short course for the complete services monitoring diagnosis and provision of the second line anti TB drugs under the supervision of dedicated health circles

 

Types of Vaccines:-

Conventional Vaccines- These vaccines use live attenuated(Ex SABIN) or killed Pathogen(IPV) in Vaccine

Recombination Vaccines:-They use Antigen,Dna or Part of genetic material of pathogen as vaccine like hepatitis B vaccine.

Internet Protocol version 6

by

Internet Protocol version 6 (IPv6) is a version of the Internet Protocol (IP). It is designed to succeed the Internet Protocol version 4 (IPv4). While IPv4 allows 32 bits for an Internet Protocol address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128 (approximately 340 undecillion or 3.4×1038) addresses. This expansion allows for many more devices and users on the internet as well as extra flexibility in allocating addresses and efficiency for routing traffic. It also eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.
IPv6 also implements additional features not present in IPv4. It simplifies aspects of address assignment (stateless address autoconfiguration), network renumbering and router announcements when changing Internet connectivity providers.
The Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks.
The Internet Protocol (IP) is the principal communications protocol used for relaying datagrams (packets) across an internetwork using theInternet Protocol Suite. Responsible for routing packets across network boundaries, it is the primary protocol that establishes the Internet.

However, the communication with the satellite was lost on 29 August 2009 and the mission was declared over. It lasted for 312 days and achieved 95 percent of its objectives.

Chandrayaan-1 was selected by the American Institute of Aeronautics and Astronautics (AIAA) as one of the recipients of its annual AIAA SPACE 2009 awards for contributions to space science and technology.

Solar Dynamics Observatory (SDO)

by

SDO is a NASA mission launched on February 11, 2010 which will observe the sun for over five years. The observatory is a part of the living with a star program. SDO’s goal is to understand the sun’s influence on earth and near-earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously. It will find out how the sun’s magnetic field is generated, structured and converted into violent solar events such as turbulent solar wind, solar flares and coronal mass ejections.
