To put an end to the COVID-19 pandemic, vaccines were developed against the virus and people eligible to receive these are encouraged to get vaccinated. How do these vaccines work? * The vaccine will not cause the disease, but will help develop the body’s first line of defense. The vaccine mimics the virus that causes the disease and triggers the creation of antibodies. No answer The presence of the virus in the vaccine will improve the innate immune response of the body. The vaccine causes a mild infection that will trigger the production of antibodies against the virus.

The world has been greatly affected by the pandemic caused by COVID-19. Countries all over the world are in constant roll-out for vaccines to be administered to its people. Between vaccines and people, what is limited and what is in excess? How can we lessen the number of excess?
From: "Towards a universal flu vaccine" Researchers are trying to create a universal influenza vaccine - one that can confer %3D immunity to all, or nearly all, strains of influenza virus. The universal vaccine will target a stable antigen that is present on all influenza viruses that does not readily mutate to different forms. The target researchers are focusing on as a universal stable antigen is on the... The H spike head. O H spike neck N spike O Viral envelope
A number of vaccines against the SARS-CoV-2 virus (which causes COVID) are currently in use. Based on what you learned about the immune system and vaccines, this vaccine should provide immunity against this virus because: a Vaccines bind to the variable region of immunoglobulins, and prevent the antibody-antigen interactions required for the virus to be released from cells. b Vaccines elicit a primary immune response and resulting memory cells specific to the viral antigens can persist in the body c Vaccines block clonal expansion of helper T cells which are required for the virus to infect cells d Vaccines block the production of cytokines e Vaccines induce cytotoxic T cells to produce antibodies specific to antigens on the virus
From: "Towards a universal flu vaccine" Each year, the flu vaccine includes antigens from two strains of Influenza A and two strains of Influenza B. These antigens are from the head of the H spikes an area that sticks out from the virus and so, is very easy for human immune cells to detect. However, the problem with using the head of the H spike as an antigen is... O The H spike head mutates very rapidly, so quickly changes to forms not recognized by human immune cells. O The H spike head is exposed on the surface of the virus for only a short period of time. Viruses quickly pull the H spikes back inside the virus, shiclding them from human immune cells. O The H spike head is often too big for the human immune cells to attack. O The H spike head is often too small for the human immune cells to bind to.
How do vaccines work in the body? How do they utilize adaptive immune response? Also, kindly give an example (i.e., COVID vaccines).
The majority of vaccines work by eliciting pathogen-specific antibodies that circulate in our bodies and protect us in the event that we are later exposed to that specific pathogen. For most viruses and bacterial toxins that we are vaccinated against, these pre-existing antibodies are protective because They induce mucus production that helps flush the toxin or virus out of the body They bind to the virus or toxin and carry it to the liver where it can be degraded O They neutralize the virus or toxin, preventing it from attaching to and entering our cells They bind to epithelial cells and induce the production of antimicrobial peptides
All of the following are true about neutralizing antibodies, except: Group of answer choices Bind to the spike protein Bind to the ACE2 receptor binding domain Prevents virus from replicating in cells Have emergency approval use for use as treatment in COVID19 Allows viruses to enter cells and replicate

A new vaccine is about to be launch anytime soon for HIV as prophylaxis using mRNA Moderna technology used in the development of Covid vaccine. If this will be successful , it will be a great breakthrough in the field of Pharmacology to help humanity fight this dreadful HIV virus. Give your thoughts about it.
How would a baby benefit from a nursing mother receiving a vaccine for COVID-19? (Make sure you cover at least two types of the mechanism of immunity involved, ) Please talk about after birth breastfeeding, not before.

When people get vaccinated for the COVID-19, which of the following will occur to them in response to the vaccine? epitopes that the immune system can recognize macrophages specific for the COVID-19 pathogen O major histocompatibility (MHC) molecules that can present an antigen O different receptors that recognize the COVID-19 pathogen O lymphocytes with receptors that can bind to the COVID-19 pathogen MacBook Pro
A researcher performs an experiment where he infects 2 mice (Mouse A and Mouse B) with herpes simplex virus (HSV). To measure the cytotoxicity of CD8+ T cells from Mouse A, he isolates CD8+ T cells from Mouse A and co-cultures them with a mixture of HSV-infected spleen cells from Mouse B. A day later, he checks the co-culture, but none of the infected spleen cells from Mouse B have been killed. What could explain this observation? a.Mouse B does not express the invariant chain (Ii) b.Mouse A and Mouse B express different MHC alleles c.Mouse A does not express TLR2/6 d.HSV immunoevasins block MHC-II expression
