Global summit on COVID-19 effect on supply of drugs and vaccines


Vaccines and Immunization

When a Vaccine is injected into the body is called as Vaccination. The reaction of the body after administration of vaccine is Immunization. The vaccine stimulates the immune system, recognizes the diseases, protects the body from infection and prevents the spread of diseases to others. Actually, the Vaccination and Immunization meanings are not same but they are often used interchangeably.

Human Vaccines-Infectious and Non Infectious

Human vaccines are used for infectious diseases in order to increase the immunization rate in host organism and helps in preventing the disease from the population. Shingles vaccines are used for eradicating the painful skin rash. There are many immunization schedules regarding preventing infectious diseases in infants and adults. DNA vaccines are used to treat non infectious diseases like allergy and cancer.

Vaccination for pregnant women

Vaccines protect both pregnant women and their baby from vaccine preventable diseases. Killed viruses vaccines can be given during pregnancy. Live viruses vaccines are not preferred for pregnant women. Mainly the pregnant women need to get vaccinated against the flu and whooping cough. In case of travelling abroad recommended vaccines are Hepatitis A and Hepatitis B vaccines. Some of the vaccines which is not preferred during pregnancy are Chickenpox (Varicella) vaccine, Measles-mumps-rubella (MMR) vaccine and Shingles (Varicella-zoster) vaccine.

HIV Vaccines

Vaccine teaches the body’s immune system to recognize and defend against harmful bacteria or viruses. Vaccines given before infected are known as preventive vaccines. Examples of preventive vaccines are such as polio, chicken pox, measles, mumps, rubella, influenza, hepatitis A and B, HPV. Actually vaccine does not exist for HIV but scientists are working to develop vaccine for HIV/AIDS. Vaccine for HIV can be either preventive or therapeutic.

Diabetes Vaccines

Diabetes Vaccines endeavor to prevent the T cells from attacking the body’s very own cells since because Type 1 diabetes is an autoimmune disease. The regular maintenance of Vaccines is especially significant for individuals with diabetes, as they are at an expanded hazard for medical issues and complications from vaccine-preventable diseases. Majorly, there are five vaccines for people with Diabetes such as Influenza vaccine, Tdap vaccine, Zoster vaccine, Pneumococcal vaccine and Hepatitis B vaccine.

Vaccine Adjuvants and Delivery Technologies


A vaccine made from dead or weakened germs contains natural adjuvants and help the body to produce a strong protective immune response. Due to adjuvants vaccines work effectively. Nowadays, vaccines contain small components of germs such as their proteins instead of entire bacteria or virus. From 1930s aluminum gels or aluminum salts are used as ingredients in vaccines. Due to addition of small amount of aluminums in vaccines, body builds stronger immunity against germs.

Vaccines for Immune mediated Disease

Patients with safe immune mediated inflammatory diseases (IMID), for example, RA, IBD or psoriasis, are at expanded danger of contamination, in part as a result of the disease itself, however for the most part in view of treatment with immune modulator or immunosuppressive medications. Regardless of their raised hazard for antibody preventable disease, immunization inclusion in IMID patients is shockingly low. Notwithstanding their raised hazard for antibody preventable ailment, inoculation inclusion in IMID patients is shockingly low. Clinical proof shows that inoculation of IMID patients doesn't build clinical or research facility parameters of illness action. Live antibodies are contraindicated in immune suppressed people, yet non-live immunizations can securely be given.


Immunotherapy is a method that involves in hindering or enhancing of the immune system. Immunotherapy is a type of cancer treatment and it is also called as biologic therapy. It is a type of treatment that uses substances made from living organisms to treat cancer. Types of immunotherapy used to treat cancer are such as Immune checkpoint inhibitors, T-cell transfer therapy, Monoclonal antibodies and Immune system modulators. Immunotherapy can be administered via Intravenous, Oral, Topical and Intravesical

Veterinary Vaccines

Veterinary vaccines are most powerful tools in keeping animals healthy and also protecting public health. Examples of such type of vaccines are rabies vaccines and rinderpest vaccines. In spite of human vaccines, animal vaccines can be developed and licensed quickly. Veterinary vaccines increase safe food supplies and preventing animal to human transmission of infectious diseases. To improve new advancements and technologies in veterinary vaccines there should be continuous interaction between animal and human researchers and health professionals.

Travel Immunization

While travelling, getting vaccinated will keep you safe and healthy. Travelling to some countries require proof of vaccination for certain diseases like yellow fever or polio. In case of pregnant women, additional vaccines are needed to protect from ongoing illness or weakened immune system. It is required to get vaccinated at least 4-6 weeks before you travel.


Vaccines Preclinical and Clinical Trials

Vaccines are biological pharmaceutical products which are used for prevention of hypothetical infection. Development of new vaccine involves several stages of long process. Safety of vaccines is important in all developmental phases. Preclinical trial is completed in lab measures and on animals. Clinical trial is at which the antibody is tried in people. It covers four phases of clinical trials from phase I to phase IV.

Immunization and Bioterrorism

Bioterrorism is a biological attack which intentionally releases viruses, bacteria or other germs that can kill or sicken people, livestock or crops. With bioterrorism diseases like measles, influenza, avian flu, smallpox, plague and hemorrhagic fevers have the possibility of transmission of disease from one person to another. The utilization of successful immunizations would prone to ensure lives and limit disease spread in a biological weapons emergency.

Vaccines for Unconventional Diseases

At the point when antibodies are referenced the vast majority consider vaccination against childhood infectious diseases. Be that as it may, as of late the utilizations to which antibodies are being put have drastically extended past conventional irresistible sickness applications. Antibodies right now in preclinical and clinical improvement target avoidance or treatment of a wide scope of non-irresistible infections including malignant growth, hypersensitivity, asthma, diabetes, rheumatoid joint pain, lupus, hypertension, coronary illness, corpulence, Alzheimer's disease, Parkinson’s disease and even nicotine and cocaine addiction.

Autoimmune and Inflammatory Diseases

If immune system mistakenly attacks your own body then it is called as autoimmune disease. Generally, the immune system protects body against bacteria and viruses. But in an autoimmune disease, the immune system releases autoantibodies that attack healthy cells in body. The most common autoimmune diseases are Rheumatoid arthritis, Psoriasis, Psoriatic arthritis, lupus, type 1 diabetes mellitus, Guillain Barre Syndrome, Hashimoto’s thyroiditis, Myasthenia gravis and Vasculitis.

Nanotechnology in Vaccine Delivery System

Vaccination plays a major role in controlling the infectious diseases. Nowadays, attention has been directed towards using nanoparticles as delivery vehicles for vaccines. The vaccine is either encapsulated within or onto the surface of nanoparticles. Due to their size, stability and degradation rate nanoparticles have been proved efficient.

Adaptive immune system


The adaptive immune system composed of highly specialized and systemic cells. It eliminates pathogens or prevents their growth. It is also known as Acquired immune system and specific immune system. The major functions of Acquired immunity are recognition of specific antigens, generating response and development of immunological memory.

Pediatric Vaccination

Pediatric Vaccination protects your child from savage sickness and also keeps other children safe by reducing serious illness that used to spread from child to child. Some of the recommended Pediatric Vaccines from birth to age 18 are DTaP (Diphtheria, Tetanus and Pertussis), Hepatitis A, Hepatitis B, Haemophilus Influenza Type b, Human Papillomavirus, Flu, Polio, MMR (Measles, Mumps and Rubella), Meningococcal, Pneumococcal, Rotavirus and Chickenpox.

Haematopoietic, Lymphoid Malignancies and Immune System Development

Haematopoietic and Lymphoid Malignancies are the tumors which affect the blood, bone marrow, lymph and lymphatic system. Since these tissues are connected through both the circulatory system and the immune system, if one tissue is affected and it will affect the other tissue also and it leads to myeloproliferation and lymphoproliferation. Our immune system protects people against germs and microbes. The essential lymphoid organs are the bone marrow and thymus. These are the locales at which haematopoiesis happens and immature lymphocytes develop, create and separate.


Immunogenetics is a branch of immunology concerned with the study of the genetic basis of the immune response. It deals with the interrelations of heredity, illness and the immune system with respect to the manner by which the hereditary data required to create the decent variety of antibodies required by the immune system which is stored in the genome, transmitted from one generation to the next and expressed in the organism.

How deadly is the Coronavirus?

Coronaviruses (CoV) are a large family of viruses that cause sickness from normal virus to serious ailments such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). An epic coronavirus (nCoV) is another strain that has not been recently recognized in people. Coronaviruses are zoonotic which means they are transmitted from animals to people. Common symptoms are respiratory side effects, fever, cough, brevity of breath and breathing challenges. In severe cases, it leads to pneumonia, severe acute respiratory syndrome, kidney failure and even it leads to death. Standard proposals to forestall contamination spread include hand washing, covering mouth and nose while coughing and sneezing, completely cooking meat and eggs.
