Abstract

The first vaccine vial was developed a few centuries ago, and it has resulted in a significant reduction in infectious disease morbidity and mortality. According to the World Health Organization (WHO), the discovery of the novel virus and the disease, as well as its steady progression to a global pandemic with confirmed cases and reported deaths, was extremely catastrophic. This resulted in an unexpected need for preventative and cost-effective measures to mitigate the virus's devastating impact, followed by accelerated competition among pharmaceutical behemoths to manufacture and dispense vaccines at an exponential rate. Non-pharmaceutical medications, such as mandated face mask policies, travel restrictions, and widespread disinfectant use, were somewhat effective in mitigating the catastrophic effect.

Introduction

This pathogen's disease spectrum ranges from a mild self-limiting infection to potentially fatal disease, with inflated morbidity and mortality figures for individuals with coexisting morbidities like diabetes, obesity, and other lifestyle diseases, as well as poorer outcomes in patients with respiratory comorbidities like COPD.Non-pharmaceutical medications, such as mandated face mask policies, travel restrictions, and widespread disinfectant use, were somewhat successful in mitigating the catastrophic effect, but it was up to vaccination strategies and other medical interventions to combat and subdue this international health threat. However, the need to ensure current and future pandemic preparedness presents a number of challenges, including equitable vaccine access and a rising trend of vaccine hesitancy at the individual and international levels, which are beyond the scope of this discussion. With this review article, we hope to shed light on current virus variants, in-hand vaccine types, mechanism of action, effectiveness, and safety profile [1].

Literature Review

These are modified versions of viruses from a different genus that are used as vectors. It interacts with immune cells, assisting them in recognising and outwitting the pathogenic virus. When a foreign antigen is injected into the body, the immune cells activate an immune response by producing antibodyproducing B cells and T cells that seek out and destroy infected cells. T cells function by examining the storage of proteins expressed on cell surfaces. Because they can recognise the body's own proteins as'self,' when they come across a foreign protein, they initiate an immune response against the cell that is storing it. However, due to the increased risk of side effects, their use is restricted [2].

One of the most common and long-established vaccines are currently available in two forms: live attenuated and inactivated. The virus's genetic material is destroyed using chemicals, heat, and radiation to create inactivated vaccines. Because these vaccines are weak natural pathogens, the immune system activates a variety of defences, including killer T cells that recognise and destroy infected cells, helper T cells that support antibody production, and antibody-producing B cells that target pathogens. When they are introduced into the body, they elicit weak and short-lived antibody-mediated responses. As a result, they are always given with an adjuvant, and booster doses are frequently required [3].

Discussion

The pandemic was conceived as a massive threat not only to the general population, but also to a specific subset of the population, those with chronic diseases such as autoimmune conditions, those with ongoing immunosuppression, or those undergoing cancer treatment. Patients who are immunocompromised were not advised to use live attenuated vaccines because the risk of infection was higher in these patients. Similarly, while live vaccines were not recommended for cancer patients, vaccination against was recommended and deemed safe and effective for all cancer patients except those who are currently on anti-B cell therapies; in such patients, an interval of four to six months is advised for vaccination post medication cessation [4].

The immune response to the BNT162b2 vaccine has been reported to differ after the first dose. In comparison, the elderly had significantly lower levels of antibodies than younger people who had their first vaccination. According to reports, the older age group had lower neutralising titers. Infants under the age of one are at a higher risk of developing severe COVID-19; therefore, all infants over the age of six months should receive the COVID-19 vaccine. The elderly are also more likely to have adjunct comorbidities, which are a significant risk factor for developing severe COVID-19. Several clinical studies have found that vaccination benefits people with underlying medical conditions just as much as people without underlying medical conditions.

An important note about the rapidly mutating Omicron variant: while the currently available vaccines have reduced neutralising capacity to this VOC, its detection in South Africa, where vaccine coverage is only 7.5%, may indicate that the vaccines are still protective against it. In an area with less vaccine coverage, the variant is more likely to mutate and spread. Multiple preprints published around the world are quickly demonstrating that a two-dose regimen is ineffective against the Omicron variant. A three-dose booster regimen has been shown to be more effective at protecting against and reducing morbid disease in people who have been exposed to this VOC. Several countries began testing various vaccines.

When it comes to autoimmune diseases, specifically multiple sclerosis, vaccination is advocated primarily without treatment discontinuation, owing to the possibility of disease worsening or relapses following therapy discontinuation. Vaccination is recommended for all patients with irritable bowel syndrome (IBS), but live attenuated vaccines are not recommended, and for patients with acute presentations, a gap before vaccination is recommended when the patient is taking a lower dose of corticosteroids [5,6].

Conclusion

The availability of so many vaccines in such a short period of time represents a huge victory for medical science. Within a year of the emergence of SARSCOV2, vaccines were prepared, phase III trials were initiated, and data was available to develop vaccine administration strategies. So far, the efficacy and safety of various COVID vaccines have been encouraging, and they may be a step forward in halting this pandemic. The need to ensure current and future pandemic preparedness presents numerous challenges, including equitable vaccine access and an increasing trend of vaccine hesitancy at the individual and international levels, which are beyond the scope of this discussion.

The next challenge is to increase global vaccine uptake in order to reduce transmission. In this age of globalisation, no country is safe until the entire world population develops mass immunity. Putting in place border control measures can help in the short term, but for long-term protection, it is critical that vaccine uptake is high everywhere in the world, not just in developed countries, as this will support variant emergence and thus reduce vaccine efficacy. Despite mass production of vaccines, current stocks may not be sufficient to meet the demand. Work should be done to help low-income countries become as self-sufficient in vaccine production as possible. Finally, the resources and investment used to produce COVID vaccines, as well as the new vaccine technologies developed, should not be limited to COVID and should be replicated to combat other infectious diseases.
